To compare clinical and radiological outcomes of conventional medial and lateral approaches for total knee replacement in the valgus osteoarthritic knee.
Methods
In this randomized controlled trial, twenty-one patients with valgus knee osteoarthritis were randomized to either receive a total knee replacement through medial or lateral approach. Primary outcome was radiographic patellar tilt. Secondary outcomes were visual analogue scale of pain, postoperative levels of hemoglobin and clinical aspect of the operative wound.
Results
Groups were comparable. Mean lateral tilt of the patella was 3.1 degrees in lateral approach group (Standard Deviation ± 5.3) and 18 degrees in the medial approach group (Standard Deviation ± 10.2), with p=0.02. There were no differences within secondary outcomes.
Conclusion
Lateral approach provided better patellar tilt following total knee replacement in valgus osteoarthritic knee.
