Displaced acetabular fractures that occur during insertion of cementless acetabular component are a rare but very serious complication. We report two cases that were treated successfully with the utilization of an acetabular reconstruction cage and morsellized allografts.
Revision arthroplasty of a Judet polymethylmethacrylate (PMMA) hip hemiprosthesis was performed 51 years after implantation. This makes it the first implant to have survived for longer than 50 years. No signs of aggressive osteolysis were found on histologic analysis, which confirms good tissue...
It is far from clear how best to define the proper strength of soft-tissue tensioning in total knee arthroplasty (TKA). We attached a torque driver to the Monogram balancer/tensor device and measured soft-tissue tension in full extension and 90° flexion during TKA. In our surgical procedure,...
We report the technique and results of a cruciform lateral release performed on 35 consecutive knees having ≥15° of valgus with minimum 2-year follow-up. The posterior cruciate ligament (PCL) was preserved in all knees. Preoperative valgus averaged 17°, and range of motion averaged 10° to...
We report the dislocation of 6 liners out of the metal backing shells of Harris Galante II cementless total hip prostheses implanted between 1993 and 1996. The time between primary implantation and failure varied from 46 to 95 months. The dislocations were probably the result of suboptimal...
Posterior-stabilized (PS) prostheses have been used extensively in total knee arthroplasty (TKA), with excellent long-term results. The key feature of these prostheses is the femoral cam and tibial post mechanism that limits posterior displacement and produces femoral rollback. Although...
The purpose of this study was to determine whether screws placed beneath the medial tibial plateau in cemented total knee arthroplasty helps prevent collapse of the medial tibia. A previous study found that the AGC all-polyethylene tibial component had a 14% rate of collapse of the medial...
