A Single-Incision Technique for Distal Biceps Repair Using a Flexible Reamer.

Distal biceps tendon ruptures are rare injuries that usually occur in middle-aged men. Most of these injuries are repaired acutely to restore preinjury function and strength. There is concern regarding the higher prevalence of certain complications with the double-incision technique.

Arthroscopic Piriformis Release-A Technique for Sciatic Nerve Decompression.

Various techniques for piriformis muscle release have been published previously. However, it is imperative we continue to improve on existing techniques as well as develop new ones that may further optimize outcomes. Therefore, we aimed to describe an endoscopic technique for the release of the piriformis muscle in those with symptoms of sciatic nerve compression.

Total Shoulder Arthroplasty Demographics, Incidence, and Complications-A Nationwide Inpatient Sample Database Study.

Introduction: Total shoulder arthroplasty (TSA) has become a popular and successful surgery to treat advanced glenohumeral arthritis, rotator cuff arthropathy, and proximal humerus fractures. Historical data is available investigating the epidemiology of total shoulder arthroplasty with regard to patient characteristics, outcomes, and complications; however, there is a lack of studies investigating the most recent and up to date national trends related to shoulder replacement. The purpose of this study was to evaluate changes in the annual incidence, various demographics, and complications of TSA in America.

Biomechanical consequences of a complete radial tear adjacent to the medial meniscus posterior root attachment site: in situ pull-out repair restores derangement of joint mechanics.

Background: Complete radial tears near the medial meniscus posterior root attachment site disrupt the circumferential integrity of the meniscus (similar to a posterior root avulsion). These tears can compromise the circumferential integrity, and they have been reported in biomechanical studies to be comparable with the meniscectomized state.

Purpose: To quantify the tibiofemoral contact pressure and contact area changes that occur in cadaveric knees from complete posterior horn radial tears and subsequent repairs of the medial meniscus adjacent to the posterior root attachment site.

Ice hockey goaltender rehabilitation, including on-ice progression, after arthroscopic hip surgery for femoroacetabular impingement.

Ice hockey goaltenders, especially those who employ the butterfly technique, are a specialized population of athletes because of the unique physical demands that the position places on their lower extremities, specifically at the hip. It is no surprise that hip injuries are a common occurrence among goalies. A review of the biomechanical literature has demonstrated that stresses on the hip while in flexion and end-range internal rotation, the position goaltenders commonly use, put the hip at risk for injury and are likely a major contributing factor to overuse hip injuries.

Posterior cruciate ligament tears: functional and postoperative rehabilitation.

Purpose: Historically, the results of posterior cruciate ligament (PCL) reconstructions are not as favourable as anterior cruciate ligament (ACL) reconstructions, and it is well recognized that nonoperative treatment and postoperative rehabilitation for PCL injuries must be altered compared to those for ACL injuries. The purpose of this article was to review current peer-reviewed PCL rehabilitation programmes and to recommend a nonoperative and postoperative programme based on basic science and published outcomes studies.

Methods: To discover the current practices being used to rehabilitate PCL injuries, we conducted a search of PubMed with the terms "posterior cruciate ligament" and "rehabilitation" from 1983 to 2011.

Double-Bundle Posterior Cruciate Ligament Reconstruction Technique with Use of Endoscopic Femoral Graft Placement.

Introduction: As the varied results seen after posterior cruciate ligament (PCL) reconstructions might be due to surgical techniques that fail to reconstruct both functional bundles of the PCL and that injure the vastus medialis obliquus muscle, we developed a technique to address these problems and thus improve patient outcomes.

Step 1 Examine Under Anesthesia: Assess range of motion and patellofemoral stability; perform stress tests, Lachman and pseudo-Lachman tests, pivot shift test, drawer tests, reverse pivot shift test, and dial test.

Step 2 Perform Arthroscopy: Preserve any remnants of PCL at anterolateral and posteromedial bundle attachment sites to promote vascular healing.
