Minimally Invasive Surgical Approaches In Total Knee Arthroplasty
Completed · Not applicable
Conditions studied: Knee Osteoarthritis
In brief
The hypothesis of the proposed study is that performing total knee arthroplasty through a mini subvastus approach results in statistically significant differences in one or more of the above functional outcome measures, when compared in a blinded, prospective, controlled, randomized manner to mini-medial arthrotomy approach. 1. Analyses of lower extremity functional activities (gait and stairs) 2. Strength of thigh musculature 3. Self-assessment of the functional outcomes 4. Return to the activities of daily living and sports activities
