Background: Knee arthroplasty refers to the surgical reconstruction of the knee joint, commonly known as total knee replacement. Prior research has indicated that undergoing knee arthroscopy prior to total knee arthroplasty (TKA) may lead to suboptimal results. Hence the present study was conducted to evaluate the impact of prior arthroscopic procedures on the outcomes and complication rates of total knee arthroplasty. Materials & Methods: A cohort of 50 patients diagnosed with grade 4 osteoarthritis, as classified by the Kellgren-Lawrence system, participated in the study following total knee arthroplasty (TKA). The inclusion criteria specified that all participants had undergone primary TKA procedures. The patients were categorized into two distinct groups. Those exhibiting mechanical symptoms attributable to degenerative meniscus tears who subsequently underwent knee arthroscopy (n=25), and those who did not experience such symptoms (n=25). Clinical and demographic data were meticulously documented. The outcome measures included the visual analog scale (VAS), the McMaster Universities Osteoarthritis Index (WOMAC), the Knee Society scoring system (KSS), and the range of motion (ROM) of the knee, all of which were assessed preoperatively and at the final follow-up. Results:The mean age of the patients of Previous arthroscopy surgery group and Previous arthroscopy surgery free group was 60.8 years and 61.7 years respectively. Majority proportion of patients of both the study groups were males. Right side involvement occurred in majority proportion of patients. Both the groups were comparable in terms of BMI. Non-significant results were obtained while comparing VAS, WOMAC, KSS and ROM at final follow-up in between the two study groups. Conclusion: Clinical outcomes and complications were comparable between patients who underwent primary total knee arthroplasty (TKA) and those who had previously received knee arthroscopy.
