Long-term Results of Partial Release Versus Nonrelease of the Posterior Cruciate Ligament at Cruciate-Retaining Total Knee Arthroplasty: Minimum 15-Year Follow-up.

The goal of this study was to compare the clinical and radiologic results of posterior cruciate ligament (PCL) partial release and PCL nonrelease in performing cruciate-retaining total knee arthroplasty (CR-TKA) for a long-term follow-up period of greater than 15 years. A total of 224 patients underwent CR-TKA in our hospital from June 1996 to April 2002 with greater than 15 years of follow-up. We divided the subjects into 2 groups based on release of the PCL.

Outcomes of Wedge Wing in the Lag Screw for Unstable Intertrochanteric Fractures in Elderly Patients.

Purpose: To evaluate clinical-functional and radiologic outcomes of elderly patients with an unstable intertrochanteric femur fracture treated with a wedge wing in the lag screw.

Materials And Methods: Forty-eight patients treated with the Dyna Locking Trochanteric nail (DLT nail) to resolve an unstable intertrochanteric femur fracture were reviewed retrospectively. Based on AO/OTA classification, Fracture 31-A2 (34 cases) and 31-A3 (14 cases) were included in the analysis.

Results of Decompression Alone in Patients with Lumbar Spinal Stenosis and Degenerative Spondylolisthesis: A Minimum 5-Year Follow-up.

Background: Surgical treatment consisting of decompression and fusion is generally known to produce good clinical results for lumbar spinal stenosis with degenerative spondylolisthesis. However, the clinical outcome of decompression alone, without fusion, remains unclear, and long-term follow-up results are scarce. This study aimed to retrospectively analyze the 5-year clinical results of decompression only in patients with lumbar spinal stenosis and degenerative spondylolisthesis.
