ABSTRACT
PURPOSE:
To evaluate midterm results after microfracture in osteoarthritic knees. MATERIALS ANDMETHODS:
Between October 1997 and April 2006, 67 osteoarthritic knees, with minimum 4-year follow-up, underwent microfracture. Baumgaertner scores were evaluated to determine clinical results. Radiological results were assessed based on joint space widening and improvement of mechanical axis deviation. Joint space widening was calculated by comparing the preoperative joint space with the final follow-up joint space. Varus deformity was evaluated on orthoroentgenogram and recorded as a percentile of the point at which the mechanical axis intersected a line extending from the center of the knee to medial border of the medial tibial condyle. The figure was expressed as MA%.RESULTS:
The average Baumgaertner score at final follow-up was 7.0. The average joint space changed from 2.74 mm to 4.22 mm on AP radiographs and from 1.91 mm to 3.85 mm on lateral radiographs. Average MA% was 57.5% preoperatively and 45.8% at final follow-up. Clinical and radiological improvements were maintained in most cases followed for more than 4 years. Four patients had total knee arthroplasty after an average of 4.1 years.CONCLUSION:
We noted pain relief, joint space widening, and improvement of mechanical axis after microfracture for degenerative arthritis of the knee. Maintenance of clinical and radiological improvement was observed at midterm follow-up.
