Technical Pearls for Arthroscopic Labral Augmentation of the Hip

Our recent understanding of the importance of the acetabular labral suction seal has placed preserving labral integrity as a guiding principle in hip preservation surgery. In cases with a hypoplastic labrum and intact chondrolabral junction, labral augmentation presents as a viable alternative and an often preferred treatment option over labral reconstruction. At this time, there are few studies that have described the technical pearls of performing labral augmentation of the hip. In this technique guide, we describe, in detail, the kite technique for the introduction, control, and acetabular fixation of a hip labral augmentation graft. Comparable to flying a kite with 2 fly lines and to the previously described kite technique for hip labral reconstruction, the kite technique for labral augmentation is based on the principle that the use of 2 control sutures in a pulley system creates an efficient method to accurately and reproducibly facilitate graft passage and fixation during arthroscopic labral augmentation procedures

Revision Patellar Tendon Repair With Anchors, Allograft Augmentation, and Suspensory Fixation

Ruptures of the patellar tendon are rare but potentially devastating injuries reported to occur most commonly in active males in their third and fourth decades of life. Repair failure rates have been reported to range between 2% and 50% based on surgical technique used. There are several inherent challenges associated with revision patellar tendon repair, including quadriceps atrophy, contracture, tissue loss, excessive scarring, and improper patella height. There remains no consensus regarding ideal revision patellar tendon repair technique. The purpose of this Technical Note is to describe our preferred method for revision patellar tendon repair using suture anchors and allograft augmentation with adjustable loop suspensory fixation. On the basis of recent studies, we have carefully chosen our fixation and augmentation methods that have shown biomechanical promise, while allowing the surgeon to carefully titrate the patellar tendon length and accommodate for some patellar tendon tissue loss

Glenohumeral Resurfacing in Young, Active Patients With End-Stage Osteoarthritis of the Shoulder

Treatment of end-stage glenohumeral arthritis in young patients is a challenge; however, there is a lack of consensus on optimal treatment algorithms. A thorough history and physical examination are essential. Nonoperative treatments should first be attempted, whereas surgical options range from arthroscopic debridement to arthroplasty. One arthroplasty option is glenohumeral resurfacing with the objective of maintaining more native anatomy and bone stock. The described treatment includes a hemi-cap implant for the humerus and inlay polyethylene glenoid. While hemi-caps have been successfully used for decades, inlay glenoid implants are a more modern treatment, with the objective of less glenoid loosening, the typical complication and failure method in young patients. With the potential for greater longevity and preservation of anatomy, glenohumeral resurfacing for end-stage shoulder arthritis is an important treatment option to consider before total shoulder arthroplasty. This Technical Note describes resurfacing of the glenohumeral joint in a young, active patient presenting with extensive osteoarthritis on both the glenoid and humerus after a previous failed Trillat stabilization

Segmental Meniscus Allograft Transplantation

Meniscal tears treated with partial meniscectomies have been shown to significantly increase contract pressures within the tibiofemoral joint, and a complete focal meniscal deficiency may render the entirety of the meniscus functionally incompetent. Although various techniques of meniscal transplantation have been described, these techniques may require the excision of a considerable amount of healthy meniscal tissue. Furthermore, failures continue to frequently occur. Therefore, attempts to restoring normal knee kinematics and biomechanical forces are essential. Segmental meniscus allograft transplantations may offer the advantage of a robust repair by both maintaining knee biomechanics and biology while maximizing preservation of native meniscal tissue. Also, most meniscal deficiency involves only a portion of the meniscus, and thus we developed this technique to segmentally transplant only the deficient portion. The purpose of this Technical Note is to describe a technique of segmental medial meniscus allograft transplantation in a patient with focal medial meniscus deficiency

Primary Acromioclavicular-Coracoclavicular Reconstruction Using 2 Allografts, TightRope, and Stabilization to the Acromion

Acromioclavicular (AC) joint injuries are a common cause of shoulder pain, particularly among young athletes participating in contact sports. Injuries to the AC joint most commonly occur from direct impact at the acromion and are classified as types I to VI. Although most AC joint injuries can be treated nonoperatively, types IV to VI are best treated with surgery, with type III being controversial and most surgeons recommending an initial trial of nonoperative treatment. Although numerous surgical techniques have been described, no gold standard technique has been established. Biomechanical testing suggests that anatomic reconstruction of both the AC and coracoclavicular ligaments results in a superior surgical construct. The objective of this Technical Note is to describe our preferred technique for the primary treatment of AC joint instability in the acute and chronic setting. Using 2 free tendon grafts in combination with a cortical button suspensory device combines the advantages of a nonrigid biologic and anatomic AC and coracoclavicular ligament reconstruction while benefiting from the strength of a cortical suspensory device in resisting displacement of the AC joint
