dc.description.abstract | High-flexion knee prosthesis designs are generally thought to be of benefit only in patients with a satisfactory preoperative flexion angle. The aim of the study was to evaluate whether high-flexion designs were indeed worthless in osteoarthritis patients with severe preoperative flexion limitation. The postoperative maximum flexion was compared in osteoarthritis patients with a preoperative maximum flexion of 100A degrees or less, using LPS and LPS-flex implants (NexGenA (R); Zimmer, Warsaw, IN) in total knee arthroplasties. Data on 39 knees in the LPS group and 41 in the LPS-flex group, with a minimum of 2 years of follow-up, were reviewed retrospectively, focused on the postoperative maximum flexion. Two years after operation, the LPS-flex group had a mean postoperative maximum flexion of 131 +/- A 10A degrees (range, 105-140A degrees), which was significantly higher than the 121 +/- A 12A degrees (range, 95-140A degrees) in the LPS group (P < 0.001). In the LPS-flex group, about half of the knees (n = 18, 44%) could achieve a maximum flexion of 140A degrees postoperatively, but in the LPS group only five knees (13%) achieved a maximum flexion of 140A degrees. Despite a different period of the operation between groups, this study suggested that osteoarthritis patients with severe preoperative flexion limitation could achieve more postoperative gain in flexion when a high-flexion prosthesis was used, compared to the flexion obtained using a standard prosthesis. | - |
