RESUMEN
Introduction Anterior cruciate ligament reconstruction (ACLR) with autografts has been available for decades; however, the choice of graft is still debated. Here, we compared the functional outcomes of the two most widely used autografts, bone-patella tendon-bone (BPTB) and quadruple-stranded semitendinosus/gracilis (ST/G) autografts, at six months following ACLR. Materials and methods This prospective study was performed in the Department of Orthopedics of Yenepoya Medical College and Hospital located in Mangalore, Karnataka, India, a tertiary care institute over a period of 18 months (November 2018 to April 2020). The study included 38 adult patients who underwent ACLR and were randomly divided into two groups: BPTB autograft (n=19) or ST/G autograft (N=19). The patients were followed up at one-, three-, and six months. Postoperatively, surgical morbidity, knee stability functional outcome on Lysholm score, and knee range of motion (ROM) were assessed. Results The groups were homogenous and comparable regarding age, sex, side of ACL affected, duration of tear to treatment, and muscle wasting (all p-values > 0.05). At six months, the majority of the patients had a tibial translation of 0-2 mm on the Lachman test and anterior drawer test, and the groups did not differ significantly (both p-values > 0.05). Additionally, at six months, both groups demonstrated a significant increase in mean Lysholm score and mean ROM (both p-values < 0.001). However, the groups did not differ in mean Lysholm score and mean ROM at baseline and any of the follow-up visits (all p-values > 0.05). Conclusion At six months, ACLR with BPTB and ST/G autografts produced significant and comparable knee stability, functional outcome, and ROM.
RESUMEN
This experiment aimed to evaluate the impact of continuous and intermittent thermal stress during early embryogenesis on hatchability, physiological body reaction, ovary weight, and follicle development of quails. A total of 540 eggs were divided into 3 equal groups (3 groups × 6 replicates × 30 eggs). In the first group (control), eggs were incubated at normal incubation conditions (37.5°C and 50-55% relative humidity) from day 0 till hatching. In the second group (continuous thermal stress [CTS]), eggs were daily exposed to 39.5°C and 50 to 55% during the early embryogenesis for 3 successive days (E4-E6) for 3 h (12:00-15:00). In the third group (intermittent thermal stress [ITS]), eggs were daily exposed to 39.5°C and 50 to 55% during the early embryogenesis for 90 min (12:00-13:30) then temperature was returned to 37.5°C for 60 min (13:30-14:30) after that the temperature was raised again for 39.5°C for 90 min (14:30-16:00) daily for 3 successive days (E4-E6). The findings showed that the highest relative water loss form egg (RWL/%) at 6 d of incubation was obtained in the CTS group (P ≤ 0.05). The hatchability rate was significantly (P ≤ 0.05) decreased in the thermal-treated groups compared with the control group. The body surface temperature and cloacal temperature in the CTS and ITS groups significantly (P ≤ 0.001) increased compared with the control group. Chick weight (g) at 5 wk old, total weight gain, daily weight gain were significantly lower (P ≤ 0.05) in the CTS group compared with the control group. Triiodothyronine (T3) hormone concentration and globulin level were significantly (P ≤ 0.05) lower in the CTS and ITS groups compared with the control. The ovarian follicle weights (first, second, third, fourth, and fifth) and the diameter of the large follicle (fifth follicle) were significantly (P ≤ 0.01) decreased by increasing incubation temperature. From these findings, it could be concluded that the hatchability and body weight at sexual maturity for quails produced from eggs exposed to CTS and IST were significantly decreased by 8 and 2.1% as well as 2.98 and 2.1%, respectively, compared with the control group.
