BACKGROUND Suture anchor and bone tunnel fixations are used for distal biceps tendon repairs and have not been compared. HYPOTHESIS Suture anchor fixation is equal or superior to bone tunnel fixation. STUDY DESIGN Randomized controlled in vitro study. METHODS A new fixation technique was compared to traditional bone tunnel fixation of distal biceps(More)
BACKGROUND Treatment for acromioclavicular (AC) joint pain may include distal clavicle excision (DCE). It is possible that DCE can disrupt the surrounding ligaments, leading to increased AC joint laxity. PURPOSE To determine the load to failure and stiffness of the AC joint after DCE and symmetric acromioclavicular joint resection (ACJR). STUDY DESIGN(More)
Degeneration and tearing of the long head of the biceps brachii tendon (LHBT) are common intra-articular findings, and surgical intervention including tenodesis or tenotomy is beneficial. A new arthroscopic shoulder technique may be performed through an anterior portal while one is viewing from a posterior portal: (1) Visualize the intra-articular biceps(More)
Methods to reconstruct the coracoclavicular ligaments anatomically have been described. No clear advantage of 1 technique has been elucidated. The authors' hypothesis was that the biomechanical properties of a modified knot fixation technique would be similar to the anatomical double-bundle technique. Sixteen matched cadaveric shoulders were used for this(More)
BACKGROUND The posterior interosseous nerve (PIN) is at risk for injury during one-incision distal biceps tendon repair using a cortical button. The purpose of this study was to evaluate the proximity of a cortical button to the PIN during one-incision repairs of the distal biceps tendon using human cadaveric models. METHODS In ten cadaveric elbows the(More)
BACKGROUND Biceps tenotomy and biceps tenodesis are the primary methods of treating biceps pathology. This study describes a new technique of tenotomy with the goal of autotenodesis to give the biceps a higher load to failure and decreased chance of a Popeye deformity. PURPOSE The purpose of this study was to evaluate the strength of the "biceps knot",(More)
BACKGROUND Rotator cuff tendinopathy is a frequent cause of shoulder pain that can lead to decreased strength and range of motion. Failures after using the single-row technique of rotator cuff repair have led to the development of the double-row technique, which is said to allow for more anatomical restoration of the footprint. PURPOSE To compare 5(More)
PURPOSE To describe the proximity of the lateral critical structures (peroneal nerve [PN], popliteus tendon [PT], lateral collateral ligament [LCL], and articular cartilage [AC]) to the femoral tunnel for outside-in all-epiphyseal anterior cruciate ligament (ACL) reconstruction in reference to knee flexion angle. METHODS All-epiphyseal ACL reconstructions(More)
The purpose of this study was to compare two different methods of medial patellar femoral ligament (MPFL) reconstructions: isometric and anatomic. These were then compared with the native MPFL. Fourteen fresh frozen cadaveric knees were carefully dissected to expose the MPFL. The patella was laterally translated 10 mm using an Instron and values were(More)
