Abstract Background This study was conducted with the aim to compare the effect of posterior condyle offset (PCO) changes on knee joint function of patients following total knee replacement (TKR). Methods Electronic and manual searches were performed in the PubMed, Embase, and Cochrane Library databases from inception to September 2019. Network meta-analysis combined direct and indirect evidence to assess the weighted mean difference (WMD) and surface under the cumulative ranking curves (SUCRA) of different PCO changes (PCO ≤ − 2 mm, − 2 mm < PCO < 0 mm, 0 mm ≤ PCO < 2 mm and PCO ≥ 2 mm) on knee joint function after TKR. Then 103 OA patients undergoing unilateral TKR were included and the effect of PCO on the postoperative knee function was examined. Results Totally, 5 cohort studies meeting the inclusion criteria were enrolled in this analysis. The results of meta-analysis showed that patients with 0 mm ≤ PCO < 2 mm after TKR had a better recovery of joint function (flexion contracture: 28.67%; KS functional score: 78.67%; KS knee score: 75.00%) than the remaining three groups. However, the knee flexion (77.00%) of patients with PCO ≤ − 2 mm after TKR was superior to the other three groups. Retrospective study also revealed a significant correlation between PCO changes and the flexion contracture, further flexion and KS functional score of patients after TKR, in which each functional knee score of patients with 0 mm ≤ PCO < 2 mm was better than the others. Conclusion These findings suggest a close correlation between PCO magnitude and knee joint function after TKR and that 0 mm ≤ PCO < 2 mm is superior to other changes for joint function after TKR.

Background:Indian population is mainly residing in two areas- urban and rural. The literature has shown consistent results following knee joint replacement surgeries, however these studies have been done in highly efficient and equipped hospitals in urban areas. Aim: The aim of this study was to compare outcome at a rural set-up with those at a high-end teaching or corporate hospital in urban set-up from published literature. Materials and Methods: This study was an observational and retrospective analysis. Observation data was collected from January, 2020 and April, 2021. This study included follow-up of 60 total knee joint replacements. Results: In our study of total knee joint replacement surgeries in rural teaching set- up, we achieved 95.39% results (excellent) while the remaining 4.61% results were good. Conclusion: This study confirmed that results of total knee replacement are comparable to any other highly well equipped urban center, if all basic surgical principles including aseptic precautions are stringently followed-up. Further the clinical outcomes in our cases was more surgeon dependent rather than technology dependent as all surgeries were performed by one single surgeon.
