Failure of osteochondral lesions using bioabsorbable fixation in the adolescent patient: a case report.

Injury to the chondral surface and subchondral bone can be due to osteochondritis dissecans or traumatic injury. These lesions can lead to pain, swelling, and mechanical symptoms causing functional impairments for patients. Treatment can include nonoperative management or surgical intervention including internal fixation.

Snapping popliteus tendon within an osteochondritis dissecans lesion: an unusual case of lateral knee pain.

The popliteus muscle is an important structure in the posterior knee, coursing from the distal lateral femoral condyle to the posterior tibia, and it initiates knee flexion, protects the lateral meniscus, and resists tibial external rotation. Abnormalities in the lateral femoral condyle may result in impaired tracking of the popliteus tendon over the lateral femoral condyle, causing pain and a snapping sensation. We report a case of a snapping popliteus tendon caused by an osteochondral defect of the lateral femoral condyle.

Reconstruction of the posterolateral corner of the knee with achilles tendon allograft.

Posterolateral corner injuries of the knee are relatively rare; however, they can result in significant long-term disability without appropriate treatment. They often occur in the setting of multiligament knee injuries, and as a result, diagnosis and management can be challenging. Severe injuries often require reconstruction, and both anatomic and nonanatomic techniques exist.

Results of revision anterior shoulder stabilization surgery in adolescent athletes.

Purpose: The purpose of this study was to determine failure rates, functional outcomes, and risk factors for failure after revision anterior shoulder stabilization surgery in high-risk adolescent athletes.

Methods: Adolescent athletes who underwent primary anterior shoulder stabilization were reviewed. Patients undergoing subsequent revision stabilization surgery were identified and analyzed.

Arthroscopic femoral neck osteoplasty in the treatment of femoroacetabular impingement.

Femoral neck osteoplasty is an integral component for successful treatment of femoroacetabular impingement. Current techniques allow this to be performed arthroscopically, and results are equivalent to those of open procedures when typical anterior and anterosuperior lesions are considered. The arthroscopic procedure is dependent on obtaining adequate visualization through capsular management and proper leg positioning, and it requires fluoroscopy to guide and verify an adequate resection.

Is peroneal nerve injury associated with worse function after knee dislocation?

Background: Peroneal nerve palsy is a frequent and potentially disabling complication of multiligament knee dislocation, but little information exists on the degree to which patients recover motor or sensory function after this injury, and whether having this nerve injury--with or without complete recovery--is a predictor of inferior patient-reported outcome scores.

Questions/purposes: The purposes of this study were to (1) report on motor and sensory recovery as well as patient-reported outcomes scores of patients with peroneal nerve injury from multiligament knee dislocation; (2) compare those endpoints between patients who had partial versus complete nerve injuries; and (3) compare patient-reported outcomes among patients who sustained peroneal nerve injuries after knee dislocation with a matched cohort of multiligament knee injuries without nerve injury.

Methods: Thirty-two patients were identified, but five did not have 2-year followup and are excluded (16% lost to followup).

Modest mid-term outcomes after isolated arthroscopic debridement of acetabular labral tears.

Purpose: Currently, there is a paucity of literature regarding outcomes after isolated labral debridement. The purpose of this study was to (1) report the reoperation rate following isolated labral debridement, (2) report clinical and functional outcomes after labral debridement with a minimum 2-year follow-up and (3) identify risk factors for worse clinical and functional outcomes. It was hypothesized that inferior outcomes are associated with an increasing Tönnis grade and those with untreated femoral acetabular impingement (FAI).

Limited therapeutic benefits of intra-articular cortisone injection for patients with femoro-acetabular impingement and labral tear.

Purpose: Intra-articular (IA) hip cortisone injection is commonly performed as a therapeutic modality in patients with femoral acetabular impingement (FAI). To our knowledge, there is no published data evaluating the clinical benefit of these injections. The purpose of this study was to assess the efficacy of therapeutic IA cortisone injection in these patients.

Utility of multimodal analgesia with fascia iliaca blockade for acute pain management following hip arthroscopy.

Purpose: The purpose of this study was to evaluate the utility of multimodal analgesia with fascia iliaca blockade and for acute pain control in patients undergoing hip arthroscopy.

Methods: Thirty consecutive patients undergoing primary hip arthroscopy were prospectively studied. All patients were treated preoperatively with ultrasound-guided single injection fascia iliaca blockade and multimodal analgesia.

Postfixed brachial plexus radiculopathy due to thoracic disc herniation in a collegiate wrestler: a case report.

Objective: To present the unique case of a collegiate wrestler with C7 neurologic symptoms due to T1-T2 disc herniation.

Background: A 23-year-old male collegiate wrestler injured his neck in a wrestling tournament match and experienced pain, weakness, and numbness in his left upper extremity. He completed that match and 1 additional match that day with mild symptoms.

Metal ions activate vascular endothelial cells and increase lymphocyte chemotaxis and binding.

Metal on metal articulations in hip arthroplasty offer advantages, including lower volumetric wear compared to conventional metalonpolyethylene bearings, and increased resistance to dislocation. Reports described early failures, with histologic features similar to a Type IV immune response. Mechanisms by which metal wear products cause this reaction are not completely understood.
