Professional Med J Jan ;26(08):1246-50.

To compare the minimally invasive total knee arthroplasty with standard approach total 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 and Methods: A total of one hundred (n=100) patients between age 30-80 years who were planned to 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 length of hospital stay in both groups. Results: Baseline characteristics were comparable in both the groups. In group A, mean length of hospital stay was 4.4±0.64 days while in group B it was 5.6±0.63 days (p=0.001). Similar trend was noted when data was stratified with respect to age, gender, anatomical side and BMI. Conclusion: Minimally invasive TKA resulted in shorter length of hospital stay following when compared with standard approach TKA.
