摘要

To compare the minimally invasive total knee arthroplasty with standard approachtotal knee arthroplasty in terms of mean length of post-operative hospital stay. Study Design:Randomized Controlled Trial. Setting: Department of Orthopaedics, Benazir Bhutto Hospital,Rawalpindi. Period: 06 months i.e. from 21st March 2018 to 20th September 2018. Materials andMethods: A total of one hundred (n=100) patients between age 30-80 years who were plannedto undergo total knee arthroplasty (TKA) were enrolled and randomly allocated to two groups.The patients in group A were operated through minimally invasive technique and in group B,were operated through standard approach. Outcome was measured in terms of mean lengthof hospital stay in both groups. Results: Baseline characteristics were comparable in both thegroups. In group A, mean length of hospital stay was 4.4±0.64 days while in group B it was5.6±0.63 days (p=0.001). Similar trend was noted when data was stratified with respect toage, gender, anatomical side and BMI. Conclusion: Minimally invasive TKA resulted in shorterlength of hospital stay following when compared with standard approach TKA.
