RESUMEN
INTRODUCTION: Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used as part of multimodal analgesia in total knee arthroplasty (TKA). Selective cyclooxygenase (COX)-2 inhibitors (e.g., celecoxib) are believed to have fewer gastrointestinal (GI) adverse effects than nonselective NSAIDS. Meloxicam is less selective for COX-2 than celecoxib is and partially inhibits COX-1 at higher doses. Nonetheless, some surgeons prefer using nonselective NSAIDs because of their lower expense. METHODS: Four thousand nine hundred ninety-four patients who underwent TKA between January 2015 and February 2020 and took either celecoxib (n = 3,174), meloxicam 15 mg/d (n = 1,819), or meloxicam 7.5 mg/d (n = 451) were studied. Mutlimodal postoperative analgesia protocols were otherwise similar. GI bleeding and wound complication incidence were determined, as well as average 30-day prescription costs. RESULTS: GI bleeding incidence was similar in the three cohorts (P = 0.4). The incidence of wound complications did not significantly differ between the groups: 0.06%, 0.07%, and 0.22% in the celecoxib, meloxicam 15 mg/d, and meloxicam 7.5 mg/d groups, respectively (P = 0.06). Subsituting meloxicam for celecoxib results in an average savings of $183 per prescription. DISCUSSION: Meloxicam used at higher doses (15 mg/d) does not markedly increase the risk of GI or wound complications associated with COX-1 inhibition and is less costly for multimodal analgesia after TKA.

BACKGROUND: Multimodal analgesia has become the standard of care for pain management following total knee arthroplasty (TKA). Cannabidiol (CBD) is increasingly utilized in the postoperative period. The purpose of this study was to analyze the analgesic benefits of topical CBD following primary TKA. METHODS: In this randomized double-blinded placebo-controlled trial, 80 patients undergoing primary unilateral TKA applied topical CBD (CBD; n = 19), essential oil (EO; n = 21), CBD and essential oil (CBD + EO; n = 21), or placebo (PLA; n = 19) thrice daily around the knee for two weeks postoperatively. This supplemented a standardized multimodal analgesic protocol. Outcomes included visual analog scale (VAS) pain and numeric rating scale (NRS) sleep scores (collected on postoperative day [POD] 0, 1, 2, 7, 14, 42), and cumulative postoperative opioid use (42 days). RESULTS: Demographic characteristics were similar among the four cohorts. Preoperative VAS and NRS scores were similar among groups. The CBD cohort had a higher mean VAS pain score on POD 2 compared to the EO cohort (CBD: 69.9 ± 19.3 versus. EO: 51.0 ± 18.2; P = .013). No statistically significant differences existed for VAS scores at other times, and no statistically significant differences were observed for postoperative NRS sleep scores or postoperative opioid use at any time point. CONCLUSION: Utilization of topical CBD in supplement to multimodal analgesia did not reduce pain or opioid consumption, or improve sleep scores following TKA. These results suggest that the local effects of topical CBD are not beneficial for providing additional pain relief after TKA.

BACKGROUND: The use of preoperative patient-reported outcome measure (PROM) thresholds for patient selection in arthroplasty care has been questioned recently. This study aimed to identify factors affecting achievement of the minimal clinically important difference (MCID) and patient acceptable symptom state (PASS) after total knee arthroplasty (TKA) and determine the overlap between the two outcomes. METHODS: We identified 1,239 primary, unilateral TKAs performed at a single institution in 2015-2019. PROMs including the Knee injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS-JR) and 12-item Short Form Health Survey (SF-12) were collected preoperatively and 1-year postoperatively. The likelihood of attaining PASS as per attainment of MCID was assessed. A multivariable regression was used to identify predictors of MCID and PASS. RESULTS: In total, 71.3% achieved MCID and 75.5% achieved PASS for KOOS-JR. Only 7.7% achieved MCID but not PASS, whereas almost twice this number did not achieve MCID but did achieve PASS (11.9%). Poorer preoperative KOOS-JR (OR 0.925), better SF-12 physical (OR 1.025), and mental (OR 1.027) were associated with MCID attainment. In contrast, better preoperative KOOS-JR (OR 1.030) and SF-12 mental (OR 1.025) were associated with PASS attainment. Age, gender, race, ethnicity, body mass index, Charlson index, American Society of Anesthesiologists classification, and smoking status were not significant predictors. CONCLUSION: Preoperative PROMs were associated with achieving MCID and PASS after TKA, albeit some positively and some negatively. In the era of value-based care, clinicians should not only strive to help patients "feel better" but also ensure that patients "feel good" after surgery. This study does not support the use of PROMs in prioritizing access to care.

BACKGROUND: Progressive arthritis in the unresurfaced compartments of the knee is one failure mode after partial knee arthroplasty (PKA). While progressive arthritis after PKA is typically treated with revision to TKA (rTKA), staged bicompartmental knee arthroplasty (sBiKA) -the addition of another PKA - is an alternative. This study compared outcomes of sBiKA and rTKA for progressive arthritis after PKA. METHODS: A retrospective comparative study of non-consecutive cases at four institutions were performed in patients with an intact PKA, without loosening or wear, who underwent sBiKA (n = 27) or rTKA (n = 30), for progressive osteoarthritis. Outcomes studied were new Knee Society Function and Objective Scores (KSSF, KSSO), KOOS, Jr., ROM, operative times, length of stay, complication rates and the need for reoperations. RESULTS: Mean time to conversion was 7.4 ± 6 years for sBiKA and 9.7 ± 8 for rTKA, P = .178. Patient demographics and pre-operative outcomes were similar among cohorts. At an average of 5.7 ± 3 (sBiKA) and 3.2 ± 2 years (rTKA), KOOS, Jr. significantly improved, P < .001, by an equivalent amount. Post-operative KSSO and KSSF were significantly higher in the sBiKA cohort, respectively, (90.4 ± 10 vs 72.1 ± 20, P < .001) and (80.3 ± 18 vs 67.1 ± 19, P = .011). sBiKA patients had significantly greater improvement in KSSO (30.7 ± 33 vs 5.2 ± 18, P = .003). One sBiKA patient underwent reoperation for continued pain. CONCLUSION: SBiKA has equivalent survivorship, but greater improvement in functional outcomes as rTKA at short to midterm follow-up. Given the shorter operative times and length of stay, sBiKA is a safe and cost-effective alternative to rTKA for progressive osteoarthritis following PKA. Nevertheless, further follow-up is necessary to determine whether sBiKA is a durable option.

BACKGROUND: Poor surgical ergonomics and physiological stress have been shown to impair surgical performance and cause injuries. The prevalence of musculoskeletal pain among arthroplasty surgeons is inordinately high. This study compared surgeon stress and strain during robotic-assisted total knee arthroplasty (rTKA) and conventional TKA (cTKA). METHODS: Continuous cardiorespiratory and ergonomic data of a single surgeon were measured during 40 consecutive unilateral TKAs (20 rTKAs, 20 cTKAs) using a smart garment and wearable sensors. Heart rate (HR), HR variability, respiratory rate, minute ventilation, and calorie expenditure were used as surrogate measures for physiological stress. Intraoperative ergonomics were assessed by measuring cervical and lumbar flexion, extension and rotation, and shoulder abduction/adduction. RESULTS: Mean operative time was longer for rTKA (48.2 ± 9 vs 31.8 ± 7 min, P < .001). Calories expended per minute was lower for rTKA (2.53 vs 3.50, P < .001). Total calorie expenditure in rTKA cases 11-20 was significantly lower than the first 10 (107.1 ± 27 vs 137.6 ± 24, P = .015), and lower than cTKA (112.3 ± 37). Mean HR was lower for rTKA (81.5 ± 4 vs 90.1 ± 5, P < .001). Minute ventilation was also lower for rTKA (14.9 ± 1 vs 17.0 ± 1.0 L/min, P < .001). Mean lumbar flexion as well as the percentage of time spent in a demanding flexion position >20° were significantly lower during rTKA (P < .001). CONCLUSION: rTKA resulted in less surgeon physiologic stress, energy expenditure per minute, and postural strain compared to cTKA. Robotic assistance may help to increase surgical efficiency and reduce physician workload, but further studies are needed to determine whether these benefits will reduce musculoskeletal pain and injury among surgeons.

BACKGROUND: The cost-effectiveness of robotic-assisted unicompartmental knee arthroplasty (RA-UKA) remains unclear. Time-driven activity-based costing (TDABC) has been shown to accurately reflect true resource utilization. This study aimed to compare true facility costs between RA-UKA and conventional UKA. METHODS: We identified 265 consecutive UKAs (133 RA, 132 conventional) performed at a specialty hospital in 2016-2020. Itemized facility costs were calculated using TDABC. Separate analyses including and excluding implant costs were performed. Multiple regression was performed to determine the independent effect of robotic assistance on facility costs. RESULTS: Due to longer operative time, RA-UKA patients had higher personnel costs and total facility costs ($2,270 vs $1,854, P < .001). Controlling for demographics and comorbidities, robotic assistance was associated with an increase in personnel costs of $399.25 (95% confidence interval [CI] $343.75-$454.74, P < .001), reduction in supply costs of $55.03 (95% CI $0.56-$109.50, P = .048), and increase in total facility costs of $344.27 (95% CI $265.24-$423.31, P < .001) per case. However, after factoring in implant costs, robotic assistance was associated with a reduction in total facility costs of $235.87 (95% CI $40.88-$430.85, P < .001) per case. CONCLUSION: Using TDABC, overall facility costs were lower in RA-UKA despite a longer operative time. To facilitate wider adoption of this technology, implant manufacturers may negotiate lower implant costs based on volume commitments when robotic assistance is used. These supply cost savings appear to offset a portion of the increased costs. Nonetheless, further research is needed to determine if RA-UKA can improve clinical outcomes and create value in arthroplasty.

BACKGROUND: Orthopedic surgeons experience significant musculoskeletal pain and work-related injuries while performing total joint arthroplasty (TJA). We sought to investigate the impact of operative extremity and surgeon limb dominance on surgeon physiologic stress and energy expenditure during TJA. METHODS: This was a prospective cohort study conducted at a tertiary academic practice. Cardiorespiratory data was recorded continuously in 3 high-volume arthroplasty surgeons using a smart garment that measured heart rate (HR), HR variability, respiratory rate, minute ventilation, and energy expenditure (calories) during conventional total knee (TKA) and total hip arthroplasty (THA). RESULTS: Surgeon 1 and 2 (right-handed) performed 21 right TKAs, 10 left TKAs, 13 right THAs, and 10 left THAs. Surgeon 3 (left-handed) performed 6 right TKAs, 9 left TKAs, 16 right THAs, and 10 left THAs. While performing TKA or THA, limb laterality had no significant impact on operative time and no significant differences existed in HR, HR variability, respiratory rate, minute ventilation, or energy expenditure for any right-handed or left-handed surgeons, regardless of the operative limb laterality. While performing TKA, consistently standing on the side of hand dominance was associated with decreased strain and stress, compared to always standing on the operative side. CONCLUSION: This study suggests that surgeon hand dominance and operative limb laterality do not impact energy expenditure or physiologic strain during TJA. However, consistently standing on the side of hand dominance in TKA may lead to decreased physiologic strain and stress during surgery. Further study utilizing wearable technology during TJA may provide orthopedic surgeons with information about modifiable factors that contribute to differences in physiological parameters during surgery.

BACKGROUND: Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are physically demanding, with a high prevalence of work-related injuries among arthroplasty surgeons. It is unknown whether there are differences in cardiorespiratory output for surgeons while performing THA and TKA. The objective of this study is to characterize whether differences in surgeon physiological response exist while performing primary THA vs TKA. METHODS: This is a prospective cohort study including 3 high-volume, fellowship-trained arthroplasty surgeons who wore a smart garment that recorded cardiorespiratory data on operative days during which they were performing primary conventional TKA and THA. Variables collected included patient body mass index (BMI), operative time (minutes), heart rate, heart rate variability, respiratory rate, minute ventilation, and energy expenditure (calories). RESULTS: Seventy-six consecutive cases (49 THAs and 27 TKAs) were studied. Patient BMI was similar between the 2 cohorts (P > .05), while operative time was significantly longer in TKAs (60.4 ± 12.0 vs 53.6 ± 11.8; P = .029). During THA, surgeons had a significantly higher heart rate (95.7 ± 9.1 vs 90.2 ± 8.9; P = .012), energy expenditure per minute (4.6 ± 1.23 vs 3.8 ± 1.2; P = .007), and minute ventilation (19.0 ± 3.0 vs 15.5 ± 3.3; P < .001) compared to TKA. CONCLUSION: Surgeons experience significantly higher physiological strain and stress while performing THA. While scheduling THAs and TKAs, surgeons should consider the higher physical demand associated with THAs and ensure adequate personal preparation and sequence of cases.

BACKGROUND: Anterior cruciate ligament (ACL) deficiency is commonly considered a contraindication for unicompartmental knee arthroplasty (UKA). The purpose of this study is to compare the outcomes of UKA after prior ACL reconstruction (rACL cohort) to UKA with an intact native ACL (nACL cohort). METHODS: Forty-five patients from 3 institutions who underwent medial UKA after prior rACL were matched by age, gender, preoperative function scores, and body mass index to 90 patients who underwent UKA with an intact nACL. Primary outcomes were Knee Injury and Osteoarthritis Outcome Score for Joint Replacement, Oxford Knee Scores, Knee Society Functional Scores, and Kellgren-Lawrence scores in the unresurfaced, lateral tibiofemoral compartment. Secondary outcomes were postoperative complications and the need for revision to TKA. RESULTS: At a mean of 3.6 years, all PROMs improved significantly with no differences identified between groups. The incidence of revision TKA was similar between cohorts (P = 1.00); however, the mean time to revision for progressive osteoarthritis was 4.0 years in the nACL group and 2.2 years in the rACL group. Twenty percent of rACL patients had a postoperative complication compared to 8% in the nACL group. Despite presenting with a similar degree of lateral arthritis, a greater percentage of patients developed Kellgren-Lawrence scores of ≥3 in the rACL cohort (9%) than in the nACL cohort (0%). CONCLUSION: A previously reconstructed ACL does not appear to compromise the short-term functional outcomes of UKA; however, there is a higher rate of minor complications and progression of lateral compartment arthritis, which should be considered with patients in the shared decision process.

BACKGROUND: Preoperative coagulopathy is a risk factor for perioperative blood loss. The antifibrinolytic effects of tranexamic acid (TXA) could negate the association between preoperative coagulopathy and adverse outcomes in patients undergoing total joint arthroplasty (TJA). However, no studies have evaluated this relationship. This study compared the perioperative outcomes of coagulopathic patients undergoing TJA who did and did not receive TXA. METHODS: We retrospectively reviewed 2123 primary TJAs (975 knees and 1148 hips) performed in patients with a preoperative coagulopathy. Coagulopathy was defined as international normalized ratio >1.2, partial thromboplastin time >35 seconds, or platelet count <150,000/µL. TXA was administered in 240 patients and not administered in 1883 patients. Demographics, comorbidities, and surgical details including operative time, blood loss, and thromboprophylaxis agent were recorded. Multivariate regression was used to identify factors associated with 90-day outcomes. RESULTS: Patients who received TXA had less intraoperative blood loss and 2.3 times decreased risk of 90-day complications (odds ratio [OR] 0.43, 95% confidence interval [CI] 0.20-0.85, P = .021), especially cardiovascular (2.92% vs 12.1%, P <.001) and wound complications (0.0% vs 1.59%, P = .042). TXA was also associated with shorter length of stay (beta 0.74, 95% CI 0.67-0.82, P <.001) and decreased risk of nonhome discharge (OR 0.50, 95% CI 0.29-0.83, P = .009). There was no difference in mortality or 90-day readmissions between the groups. CONCLUSION: TXA administration decreased the incidence of perioperative complications and resource utilization in patients undergoing arthroplasty with a preoperative coagulopathy identified on preadmission testing. These findings support the broader adoption of TXA in patients undergoing TJA, particularly when the patient has a preoperative coagulopathy.

BACKGROUND: As a procedure with lower surgical morbidity, unicompartmental knee arthroplasty (UKA) may present a practical solution for elderly patients with unicompartmental arthritis. However, few studies have analyzed the results of UKA in the extreme elderly. This study compared the functional and perioperative outcomes between octogenarians and age-appropriate controls undergoing UKA. METHODS: Prospectively collected data of 44 patients aged ≥80 years who underwent unilateral UKA were analyzed. Each octogenarian was matched 1:3 with 132 patients aged 65-74 years using propensity scores adjusting for gender, body mass index, Charlson comorbidity index, and preoperative scores. Knee Injury and Osteoarthritis Outcome Score for Joint Replacement and Short Form-12 were collected preoperatively and 2 years postoperatively. Complications, reoperations, readmissions, and unplanned visits were recorded up to 1 year postoperatively. RESULTS: The mean age was 70.0 ± 2.7 years in the control group and 83.0 ± 3.0 years in the octogenarian group (P < .001). The percentage of outpatient procedures was comparable (control 50.0%; octogenarian 45.5%; P = .601). With the exception of poorer Short Form-12 physical scores in octogenarians at 2 years (39.4 ± 14.1 vs 44.9 ± 9.2, P = .028), there was no difference in final postoperative scores or improvement in scores between the groups. The rate of complications, reoperations, readmissions, and emergency room visits was also similar. The five-year survivorship was 97% in the control group and 93% in the octogenarian group (P = .148). CONCLUSION: Octogenarians undergoing UKA can experience clinical outcomes that are similar to those of their younger counterparts. The clinical trajectory outlined may help clinicians provide valuable prognostic information to elderly patients and guide preoperative counseling.

BACKGROUND: Optimizing surgical trays to improve operating room efficiency and reduce costs in instrument processing is an under-appreciated strategy for cost containment. This study aimed to assess the economic impact of instrument tray optimization in total joint arthroplasty. METHODS: Thirty-five randomly selected elective primary total knee arthroplasty and total hip arthroplasty performed by 4 fellowship-trained surgeons were analyzed. Type and number of instruments used as well as timing of different steps in the sterilization process were recorded by an independent observer. Using Lean methodology, surgeons identified redundant or underutilized instruments and agreed upon the fewest number needed for each tray. Instrument utilization rates and processing time were analyzed before and after tray modifications. Annual cost savings were calculated based on a processing factor of $0.59-$11.52 per instrument. RESULTS: Only 45.5% of instruments opened for total knee arthroplasty were utilized. After optimization, 28 of 87 (32.2%) instruments were removed and the remainder could be stored in one tray. Mean set-up time decreased from 20.7 to 14.2 minutes, while 40-75 minutes were saved during the sterilization process. For total hip arthroplasty, only 36.0% of instruments were utilized. Using Lean methods, 46 of 112 (41.1%) instruments were removed and tray count was reduced to 2 trays. Mean set-up time decreased from 27.9 to 18.6 minutes, while 45-150 minutes were saved during processing. Average annual savings amounted to $281,298.05. CONCLUSION: Lean methodology can be used to eliminate redundant or underutilized instruments in total joint arthroplasty, improving surgical efficiency and generating substantial cost savings.

BACKGROUND: With the recent removal of total knee arthroplasty (TKA) from the Centers for Medicare and Medicaid Services (CMS) Inpatient Only list, facility reimbursement for outpatient TKA now falls under the Outpatient Prospective Payment System at the same rate as unicompartmental knee arthroplasty (UKA). The purpose of this study was to compare true facility costs of patients undergoing outpatient TKA with those undergoing UKA. METHODS: We reviewed a consecutive series of 2310 outpatient TKA and 231 UKA patients from 2018 to 2019. Outpatient status was defined as a hospital stay of less than 2 midnights. Facility costs were calculated using a time-driven, activity-based costing algorithm. Implants, supplies, medications, and personnel costs were compared between outpatient TKA and UKA patients. A multivariate analysis was performed to control for confounding medical and demographic variables. RESULTS: When compared with patients undergoing UKA, outpatient TKA patients had higher implant costs ($3403 vs $3081; P < .001) and overall hospital costs ($6350 vs $5594; P < .001). Outpatient TKA patients had a greater length of stay (1.2 vs 0.5 days; P < .001) and greater postoperative personnel costs ($783 vs $166; P < .001) than UKA patients. When controlling for comorbidities, outpatient TKA was associated with a $803 (P < .001) increase in overall facility costs compared with UKA. CONCLUSION: Despite equivalent reimbursement from CMS as UKA, outpatient TKA has increased facility costs to the hospital. Although implant costs can vary greatly by institution, CMS should consider appropriately reimbursing outpatient TKA for the additional personnel costs when compared with UKA.

BACKGROUND: Recent evidence has demonstrated that formal physical therapy (PT) may not be required for most patients undergoing total hip (THA) and knee (TKA) arthroplasty. This study compared the differences in costs and functional outcomes in patients receiving formal PT and those who did not follow primary THA and TKA. METHODS: We queried claims data from a single private insurer identifying patients who underwent primary THA or TKA from 2015 to 2017 in our practice. Demographics, comorbidities, number, and cost of PT visits in a 90-day episode of care were recorded. Outcomes were compared between patients using self-directed home exercises, home PT, outpatient PT, or both home and outpatient PT. A multivariate analysis was performed to identify significant predictors of outcomes. RESULTS: Of the 2971 patients included in analysis, patients using both services had higher 90-day PT costs (mean $2091, P < .001) than those using home PT alone ($1146), outpatient PT alone ($1356), or no formal PT ($0). Home PT had the greatest cost per visit for both private insurance patients ($177/visit) and Medicare Advantage patients ($157/visit), but patients using both home PT and outpatient PT services had the greatest overall PT cost, $2091 for private insurance and $1891 for Medicare Advantage. Patients who used home PT were at significantly higher risk of both complications (odds ratio = 3.21; 95% confidence interval, 2.1-4.9; P < .001) and readmissions (odds ratio = 3.4; 95% confidence interval, 2.1-5.5; P < .001). CONCLUSION: Participation in formal PT accounts for up to 8% of the episode of care following THA and TKA. The role of formal PT for most patients should take into account the cost-effectiveness of the intervention.

BACKGROUND: Web-based physical therapy (WBPT) is a potential means to reduce costs following total knee arthroplasty (TKA). Although outcomes data support the use of self-directed therapy after TKA, there is a paucity of literature evaluating its cost-effectiveness. This study aimed to determine utilization trends of either outpatient physical therapy (OPPT) or WBPT after TKA, assess the outcomes of patients based on their use of WBPT, OPPT, or both, and evaluate OPPT costs based on the amount of WBPT used. METHODS: A retrospective review of 701 patients (731 TKAs) was performed. Patients were given a prescription for OPPT and access to a self-directed WBPT program. Functional scores were obtained preoperatively and 6 months postoperatively, and the rate of manipulation under anesthesia (MUA), range of motion, and PT costs were recorded. RESULTS: About 49.8% of patients utilized WBPT, 34.7% of patients utilized WBPT and OPPT, and 23% of patients utilized neither source of therapy. Patients that utilized both WBPT and OPPT demonstrated the lowest rates of MUA. There were no differences in postoperative outcomes based on the number of WBPT logins. Overall, PT cost was 3.4× higher for those that underwent MUA. Subgroup analysis of patients that utilized WBPT revealed that the cost and number of PT visits decreased as the number of logins increased. Patients younger than 65 utilized more WBPT and OPPT while demonstrating worse outcomes (lower Knee Injury and Osteoarthritis Outcome Score for Joint Replacement postoperative scores and more MUAs). CONCLUSION: WBPT can be an effective option to offset costs associated with OPPT, without compromising outcomes.

BACKGROUND: Controlling postoperative pain and reducing opioid requirements after total knee arthroplasty remain a challenge, particularly in an era stressing rapid recovery protocols and early discharge. A single-shot adductor canal blockade (ACB) has been shown to be effective in decreasing postoperative pain. The purpose of the present study is to compare the efficacy of an anesthesiologist administered ACB and a surgeon administered intraoperative ACB. METHODS: Patients undergoing primary total knee arthroplasty were prospectively randomized to receive either an anesthesiologist administered (group 1) or surgeon administered (group 2) ACB using 15 mL of ropivacaine 0.5%. Primary outcomes were pain visual analog scale, range of motion, and opioid consumption. RESULTS: Thirty-four patients were randomized to group 1 and 29 to group 2. Opioid equivalents consumed were equal on postoperative day (POD) 0, 1, and 2. Patients in group 1 had statistically less pain on POD 0, but this did not reach clinical significance and there was no difference in pain on POD 1 or 2. Patients in group 1 had significantly increased active flexion POD 1, but there was no difference in active flexion on POD 0 or 6 weeks postop. There was no difference in patient satisfaction with pain control or short-term functional outcomes. CONCLUSION: Surgeon administered ACB is not inferior to anesthesiologist administered ACB with respect to pain, opioid consumption, range of motion, patient satisfaction, or short-term functional outcomes. Surgeon administered ACB is an effective alternative to anesthesiologist administered ACB.

BACKGROUND: Currently, the decision to resurface the patella is often made irrespective of the presence of patellar arthritis. The purpose of this study is to utilize the existing literature to assess cost-utility of routinely vs selectively resurfacing the patella. METHODS: Prospective randomized studies of patella resurfacing vs non-resurfacing in total knee arthroplasty (TKA) were identified through literature review. Data from these studies represented probabilities of varied outcomes following TKA dependent upon patella resurfacing. Using previously validated utility scores from the McKnee modified Health Utilities Index, endpoint utility values were provided for each potential outcome. RESULTS: Literature review yielded a total of 14 studies with 3,562 patients receiving 3,823 TKAs, of which 1,873 (49.0%) patellae were resurfaced. Persistent postoperative anterior knee pain occurred in 20.9% vs 13.2% (P < .001) and patella reoperation was performed in 3.7% vs 1.6% (P < .001) of unresurfaced and resurfaced patella, respectively. In studies excluding those with arthritic patellae, the incidence of anterior knee pain was equivalent between groups and reoperation decreased to 1.2% vs 0% (P = .06). Patella resurfacing provided marginally improved quality-adjusted life-years (QALY) for both selective and indiscriminate patella resurfacing. When including all studies, the incremental cost per QALY was $3,032. However, when analyzing only those studies with nonarthritic patellae, the incremental cost per QALY to resurface the patella increased to $183,584. CONCLUSION: Patellar resurfacing remains a controversial issue in TKA. Utilizing data from new prospective randomized studies, this analysis finds that routinely resurfacing arthritis-free patellae in TKA are not cost-effective.

BACKGROUND: While some advocate for unicompartmental knee arthroplasty (UKA) for isolated medial compartment osteoarthritis (OA), others favor total knee arthroplasty (TKA). The purpose of this study was to compare the functional outcomes of UKA and TKA performed for patients with unicompartmental arthritis (OA). METHODS: A study was performed on 133 patients that met strict criteria for UKA, but who underwent either medial UKA or TKA for isolated medial compartment OA based upon physician equipoise. The primary outcome-New Knee Society Score (KSS)-was assessed preoperatively and at 2 years postoperatively. A propensity score weighted regression was used to balance the groups on several key covariates, including age, gender, body mass index, and baseline KSS. RESULTS: After propensity weighting, there were no significant differences between UKA and TKA in overall baseline KSS or KSS after 2 years postoperatively. While TKA patients had demonstrated a significantly greater improvement in the symptoms KSS subscale, UKA patients had a significantly greater improvement in the function subscale. Expectations were significantly more likely to be met after UKA, but there were no differences in patient satisfaction. CONCLUSION: UKA and TKA are both highly successful options for treating patients with medial compartment OA, although functionality increased more, and expectations were more likely to be met, after UKA in this study. Given equivalent patient satisfaction after both TKA and UKA, surgeons should consider factors such as clinical experience, individual preference, cost of care, surgical risk, and recovery needs, when making treatment decisions regarding this clinical entity.

In both unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA), compared with conventional techniques robotic technology has been shown to optimize the precision of bone preparation and component alignment, reducing outliers and increasing the percentage of components aligned within 2° or 3° of the target goal. In addition, soft tissue balance can be quantified through a range of motion in UKA and TKA using the various robotic technologies available. Although the presumption has been that the improved alignment associated with robotics will improve function and implant durability, there are limited data to support that notion. Based on recent and emerging data, it may be unreasonable to presume that robotics is necessary for both UKA and TKA. In fact, despite improvements in various proxy measures, the precision of robotics may be more important for UKA than TKA, although if system costs and surgical efficiencies continue to improve, streamlining perioperative processes, reducing instrument inventory, and achieving comparable outcomes in TKA may be a reasonable goal of robotic surgery.

Semiautonomous robotic technology has been introduced to optimize accuracy of bone preparation, implant positioning, and soft tissue balance in unicompartmental knee arthroplasty (UKA), with the expectation that there will be a resultant improvement in implant durability and survivorship. Currently, roughly one-fifth of UKAs in the US are being performed with robotic assistance, and it is anticipated that there will be substantial growth in market penetration of robotics over the next decade. First-generation robotic technology improved substantially implant position compared to conventional methods; however, high capital costs, uncertainty regarding the value of advanced technologies, and the need for preoperative computed tomography (CT) scans were barriers to broader adoption. Newer image-free semiautonomous robotic technology optimizes both implant position and soft tissue balance, without the need for preoperative CT scans and with pricing and portability that make it suitable for use in an ambulatory surgery center setting, where approximately 40% of these systems are currently being utilized. This article will review the robotic experience for UKA, including rationale, system descriptions, and outcomes.
