Abstract:
PURPOSE: This study assessed the early clinical and radiological results of Minimally Invasive Surgery- Quadriceps sparing total knee arthroplasty (MIS-QS TKA), and compared these results with those of conventional TKA. MATERIALS AND METHODS: Between August 2004 and March 2005, 17 patients with bilateral TKA on their one side using a regular procedure and the other using the MIS-QS technique were evaluated and compared. The clinical assessment was performed by measuring the range of motion, Knee Society Score, and a radiological evaluation by standing anteroposterior, supine lateral, and Merchant view preoperatively, 2 weeks, 6 weeks, 3 months and 1 year after surgery. Statistical analysis was performed using a paired t-test. RESULTS: The average range of knee motion was slightly larger in the MIS-QS group at all periodsbut there was no statistical difference between the two groups. The Knee Society Score was similar at the 3 month and 1 year periods. The alignment of the implants was satisfactory in both groups and postoperative patellar alignment checked in the Merchant view was better in the MIS-QS group at all periods. CONCLUSION: There were no differences in the clinical aspects at 1 year period between the two groups. However, the MIS-QS group showed better patellar alignment than the conventional group for up to 1 year.
