PURPOSE: The aim of this study is to report the clinical effectiveness of arthroscopic-assisted reduction and internal fixation of patella fractures. MATERIALS AND METHODS: We analyzed fifteen patella fractures, which had been operated by using an arthroscopic-assisted technique from January, 2000 to April, 2003 at our hospital. After clinical follow-ups for at least 1 year, clinical analyses had been done by using the Cincinnati Knee Rating System Score, Lysholm Score Scale, and radiological findings. RESULTS: In our study group, the Cincinnati Knee Rating System scores were from 80 to 100, with a mean of 89.9. The Lysholm Scoring Scale scores ranged from 81 to 100 with a mean of 90.8 for the same group. Radiologically, we obtained complete anatomical reduction of articular surfaces in 80 percent of cases. Arthroscopic-assisted reduction for patella fractures brought clinically satisfactory results that are accurate articular surface reduction, early recovery of motion range, knee joint stability and minimal soft tissue damage, etc. CONCLUSION: The operative treatment for patella fractures using arthroscopic-assisted reduction is an effective alternative method to open reduction.
