RESUMEN
BACKGROUND: Numerous studies have reported the incidence and outcomes of injuries in the men's and women's National Basketball Association (NBA and WNBA, respectively). PURPOSE: To synthesize published data regarding the incidence and outcomes of all injuries in the NBA and WNBA in a comprehensive review. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we searched 3 electronic databases (PubMed, MEDLINE, Embase) for studies of all levels of evidence since 1990 pertaining to injuries sustained by active players in the NBA and WNBA. Studies were excluded if the cohort of interest included ≤3 active players. RESULTS: The initial search of the 3 databases yielded 1253 unique studies, of which 49 met final inclusion criteria for this review. Only 4 studies included athletes in the WNBA. Based on the mean annual incidence, the 5 most common orthopaedic sports injuries sustained in the NBA were concussions (9.5-14.9 per year), fractures of the hand (3.5-5.5 per year), lower extremity stress fractures (4.8 per year), meniscal tears (2.3-3.3 per year), and anterior cruciate ligament tears (1.5-2.6 per year). Cartilage defects treated using microfracture, Achilles tendon ruptures, and anterior cruciate ligament injuries were 3 injuries that led to significant reductions in performance measurements after injury. CONCLUSION: With advances in sports technology and statistical analysis, there is rapidly growing interest in injuries among professional basketball athletes. High-quality prospective studies are needed to understand the prevalence and effect of injuries on player performance and career length. This information can inform preventative and treatment measures taken by health care providers to protect players and guide safe return to play at a high level.

PURPOSE: There has been an increase in the use of unlinked constrained condylar knee (CCK) prostheses in primary total knee arthroplasty (TKA) for cases with significant deformities that cannot be adequately balanced in flexion and extension. However, the literature on its outcomes is limited. The goal of this study is to evaluate whether there are any clinic or radiographic outcome differences for a primary, non-stemmed, unlinked constrained TKA as compared to a control group of posterior-stabilized (PS) TKA using the same implant design. METHODS: Clinical and radiographic outcome measures for 404 cemented, non-stemmed, primary TKAs performed by two surgeons at the same institution were retrospectively reviewed. All patients underwent primary, non-stemmed components; 241 used CCK inserts and 163 used PS inserts. Preoperative deformity, knee society scores (KSS), range-of-motion (ROM), radiographic data and revision rates were compared between the CCK and PS groups. RESULTS: Both groups had comparable demographics and preoperative ROM and KSS. At similar mean follow-up times (6.1 ± 1.0 years for the CCK group and 6.3 ± 1.2 years for the PS group), no significant difference was found in ROM, KSS or radiographic outcomes. Revision rates were higher for the CCK group (2%) as compared to the HF-PS (0.6%) group (n.s). CONCLUSIONS: The particular design of cemented, primary, non-stemmed, unlinked CCK-TKA examined in this study provided similar clinical and radiographic outcomes to that of PS-TKA at midterm follow-up. LEVEL OF EVIDENCE: III.
