Arthroscopic resection of osteochondroma of the knee: two case reports

Abstract

In this article, we report two cases of arthroscopic resection of symptomatic intraarticular osteochondroma of the knee. The first case was a 27-year-old male presenting with slowly progressive left knee pain while sitting and climbing up stairs. The second case was a 24-year-old female presenting with slowly progressive right knee pain while running downhill and squatting deeply. Preoperative radiographs and magnetic resonance images revealed an intraarticular, locally expanding, mineralized mass at adjacent to the trochlea of the femur for both patients. These osteochondromas were arthroscopically resected, which led to complete relief of symptoms and return to full activity within two weeks. There has been no return of symptoms within three years and one year of follow-up, consecutively. We highlight that an arthroscopic resection of a symptomatic intraarticular osteochondroma may be less painful, has better cosmetic results and the postoperative recovery is faster, compared to the traditional open approach.
