Nonoperative Treatment for Partial Ruptures of the Lateral Collateral Ligament Occurring in Combination With Complete Ruptures of the Anterolateral Ligament: A Common Injury Pattern in Brazilian Jiu-Jitsu Athletes With Acute Knee Injury.

Background: Combined partial lateral collateral and complete anterolateral ligament (PLCCALL) injuries are a specific injury pattern seen in Brazilian jiu-jitsu (BJJ) because of the knee varus-flexion mechanism that frequently occurs during grappling.

Purpose/hypothesis: The purpose of this study was to evaluate the incidence of this injury pattern in a series of BJJ athletes with an acute knee injury and to evaluate clinical and functional outcomes after nonoperative management at a minimum follow-up of 1 year. Our hypotheses were that PLCCALL injuries are common in BJJ and that nonoperative treatment is associated with excellent clinical outcomes and return to the preinjury level of sport.

Range of motion predictability after total knee arthroplasty with medial pivot prosthesis.

Objective: To assess whether there the final range of motion (ROM) results achieved by patients undergoing total knee arthroplasty (TKA) with prosthesis using Medial Pivot design are predictable.

Methods: Between January and August of 2014, 155 patients with primary osteoarthritis of knee who underwent TKA using the prosthesis ADVANCE Medial Pivot were prospectively assessed. All ROM measures were made and recorded before, during, and after surgery.

Reconstruction of chronic patellar tendon rupture using graft from contralateral patella graft together with reinforcement from flexor tendons. Case report.

Chronic patellar tendon rupture is a rare disabling injury that is technically difficult to repair. The true prevalence of this injury is unknown. Delayed reconstruction of chronic patellar tendon rupture has yielded suboptimal clinical and functional results.
