Fixed-Bearing Posterior-Stabilized Implant versus Constrained Condylar Knee in One-Stage Bilateral Primary Arthroplasty of the Varus Knee: A Randomized Controlled Trial with Minimum 2-year Follow-Up.

Background: Severe varus deformity of the knee poses a technical challenge in balancing the flexion-extension gaps. The use of a varus-valgus constrained prosthesis is a solution to achieve coronal plane stability. The results of constrained condylar knee (CCK) implants in primary total knee arthroplasty are not well known.

An unusual combination of acetabular and pelvic fracture: is this a new subtype of acetabular fracture?

Introduction: Acetabular fractures are a common problem among young males. An acetabular fracture with disruption of the joint surface, if untreated, will rapidly lead to post-traumatic osteoarthritis. Proper reduction and internal fixation depend on accurate classification and the quality of imaging.

Chronic Achilles tendon rupture reconstruction using a free semitendinosus tendon graft transfer.

Purpose: The purpose of this study was to evaluate the outcomes following reconstruction of the chronic Achilles tendon ruptures with large gaps (>6 cm) using free semitendinosus tendon graft transfer.

Methods: There were 11 consecutive patients underwent the above-mentioned surgical technique for the treatment of chronically ruptured Achilles tendon contributed in current study and were followed up prospectively for a mean of 25 ± 3 months. The intraoperative tendon defect was greater than 6 cm in all of the patients.
