Recently published data from this pilot study indicated proximal fibular osteotomy may be an effective alternative procedure for patients with medial compartment osteoarthritis of the knee, resulting in pain relief and improved function.
Researchers studied 110 patients who underwent proximal fibular osteotomy for medial symptomatic compartment knee osteoarthritis (OA) and had at least 2 years follow-up. The patients had an average age of 59.2 years at the time of the procedure, and 79 were women. Follow-up visits were conducted at 1 month, 3 months, 6 months, 12 months and yearly, with a mean follow-up of 49.1 months. Investigators recorded VAS pain score, demographics, laterality, severity of OA, radiographic femorotibial angle (FTA), lateral joint space and American Knee Society Scores (KSS).
Results from radiographs showed all patients had bone defects of the proximal fibula. None of the patients had developed superficial or deep infections. At the final follow-up, the mean FTA was 179.4° and mean lateral joint space was 6.9 mm. Investigators found a significant difference for the mean KSS, which was 92.3 at final follow-up vs. 45 preoperatively. Both the mean postoperative VAS score and interquartile range were significantly lower compared with preoperative results. ‒ by Monica Jaramillo
