Posterolateral rotatory instability (PLRI) is the most common form of symptomatic acute and chronic elbow instability. Diagnosis is usually made using a combination of clinical tests and imaging modalities; however, in more subtle forms of instability, these measures may be equivocal. Arthroscopy is a valuable adjunct for diagnosis and treatment of PLRI. It allows direct appreciation of the instability process, quantification of the degree of instability, and identification of concurrent associated pathology. The aim of this technique article is to report a series of reproducible arthroscopic tests used for diagnosis of PLRI with examples of normal and pathologic arthroscopic findings.Chronic patellar tendon injuries are rare yet challenging to treat. Timing of surgery and graft choices are debatable. Many techniques and methods of fixation have been described with pros and cons. Functional impairment of the extensor mechanism and postoperative complications triggers the quest for finding the ideal technique. In this Technical Note, we use distally based semitendinosus (ST) looped over 2 ETHIBOND sutures. The ETHIBOND is passed through 2 vertical tunnels in the patella and retrieved proximally, docking the ST in a blind tunnel created in the lower pole of the patella. The whip-stitched free ST end is passed through a tunnel behind the tibial tubercle and sutured back to its base. A polyester tape is used to augment the repair in a circumferential manner. Postoperatively full weight bearing is allowed as tolerated in a hinged knee brace locked in extension with only passive range of motion of 0-90° allowed for 6 weeks.Clavicle fracture nonunion can lead to persistent pain and loss of shoulder function. Distal clavicle fractures have the greatest risk of nonunion and are often treated surgically. Bone grafting plays a vital role in the treatment of distal clavicle nonunion. Although multiple options for bone graft exist, the iliac crest has long been considered the gold standard for harvest. Despite its extensive use, multiple complications have been associated with iliac crest bone graft harvest. We advocate a surgical technique for arthroscopic bone graft harvest from the proximal humerus with open reduction and internal fixation of an ipsilateral distal clavicle nonunion.The primary repair technique of acute anterior cruciate ligament (ACL) tears has been controversially discussed over the past few decades. Many different suture techniques have been reported for ACL repair, but these procedures showed high re-rupture rates and poor results. Recently, the literature has reported excellent outcomes with primary ACL repair. There has been a resurging interest in modernizing and augmenting primary ACL repair. This article describes a technique that uses internal brace augmentation and a knotless anchor (Arthrex) implant for primary anatomic double-bundle ACL repair after an acute proximal ACL tear. This technique aims to advocate natural healing by the high-strength internal brace augmentation and knotless anchor as a provisional scaffold during the healing phase and early mobilization. This technique might be an alternative to conventional ACL reconstruction in the appropriate selection of patients.Revision anterior cruciate ligament surgery is a technically demanding procedure. Mal-positioned tunnels together with bone loss and its management are some of the difficulties and challenges faced. Two-staged procedures have successfully been used to tackle those challenges. We present a technique that is safe, reliable, reproducible, and economic in the management of bone defects faced in anterior cruciate ligament revision surgery by using iliac crest bone graft. Preoperative assessment of tunnel position and size is done by computed tomography. Tri-cortical iliac crest bone graft is harvested through a trap door. selleck compound It is then shaped to fit the tunnels to be filled. It is tapered at the advancing end to facilitate introduction. Mounted on a passing pin and a drill bit, the graft is arthroscopically introduced into the femoral and tibial tunnels. The second stage is performed after the graft has incorporated, as seen on postoperative computed tomography, done at approximately 3 months after the first stage. Iliac crest provides a natural abundant reservoir for bone graft and has all the advantages of being an autograft. With good meticulous technique, complications can be avoided with less donor-site morbidity. This technique is safe, reliable, and reproducible. It provides an ample amount of graft and harvest does not rely on implants; hence, it is economic.The optimal management of anterior shoulder instability continues to be a challenge. The presence of an anterior glenoid rim fracture in the context of a glenohumeral dislocation, also called "bony Bankart lesion," can alter therapeutic behavior. Reduction and fixation of the bone fragment has been shown to greatly reduce the risk of recurrence once bone consolidation is achieved. However, there is no gold standard surgical technique. Stability of fixation and the healing of the bony fragment are still a concern, and there are no clinical studies comparing the different techniques to date. The aim of this report is to describe an arthroscopic double-point fragment fixation technique in lateral decubitus for the treatment of an acute traumatic shoulder dislocation with a bony Bankart lesion.Instabilities of the subtalar joint are commonly overlooked or mismanaged, and chronic instability is a debilitating condition leading to premature joint degeneration. Several methods of treatment have been described, mainly screw fixation, arthrodesis, or ligament reconstruction. Most studies describe open methods for ligament reconstruction. We describe an original technique for "all-inside" arthroscopic graft reconstruction of the interosseous talocalcaneal ligament for subtalar instability.Tenodesis and tenotomy of the long head of the biceps are treatment options for a wide range of pathologies without clear superior technique or site of fixation. Clinical outcomes comparing numerous techniques for tenotomy versus tenodesis have resulted in similar pain relief; however, tenotomy may result in a cosmetic "Popeye" deformity and fatigue pain. We present a quick, simple, and knotless technique for tenodesis of the long head of the biceps at the proximal aspect of the bicipital grove that can be completed entirely arthroscopically. This technique uses suture to secure a tenotomized proximal biceps tendon to a knotless anchor just proximal to the subscapularis tendon at the proximal biceps groove. The tensionless repair allows the biceps to scar within the biceps groove, thereby reducing subsidence and formation of a "Popeye" deformity and fatigue pain in the biceps seen with tenotomy alone while eliminating the ability to overtension.
