Purpose: To evaluate the incidence of early postoperative complications and revision surgery in patients who underwent primary medial ulnar collateral ligament (MUCL) repair with minimum of 2-year follow-up. Methods: A retrospective review of a national insurance database was conducted to identify patients with MUCL injuries who underwent primary MUCL repair between 2015 to 2020 with minimum 2-year follow-up. Patients >40 years of age and those who had concomitant elbow fractures or dislocations, lateral UCL injures, medial epicondylitis, elbow arthritis, or a history of previous elbow injury/surgery were excluded. The number of patients who underwent a concomitant ulnar nerve procedure (transposition or decompression) during the primary MUCL repair was recorded. Complications within 90 days of surgery and the incidence and timing of subsequent ipsilateral ulnar nerve surgery or revision MUCL surgery were assessed. Results: A total of 313 patients (63.6% male) were included. The mean age was 20.3 ± 6.9 years, and mean follow-up was 3.7 ± 1.3 years. Concomitant ulnar nerve transposition or decompression was performed in 34.2% (N = 107). The early postoperative complication rate was 7.3% (N = 23). The most common complication was ulnar neuropathy (5.8%, N = 18). Wound complications, elbow stiffness, and medial epicondyle fractures were much less common (N = 5). Sixteen of 18 (88.9%) patients with postoperative ulnar neuropathy underwent transposition or decompression at the time of primary repair. Of these 18 patients, 5 (27.8%) underwent a subsequent ulnar nerve surgery (1 primary and 4 secondary), with the majority occurring within 6 months. The incidence of revision MUCL surgery was low (1.0%, N=3), with all 3 patients undergoing MUCL reconstruction. Conclusions: There was a low incidence of early postoperative complications (7.3%) and 2-year revision MUCL surgery (1.0%) in young patients who underwent primary MUCL repair with no additional ligamentous, fracture, and dislocation-related diagnoses. All 3 (1.0%) MUCL revisions underwent reconstruction. Level of Evidence: Level IV, therapeutic case series.

Dislocation of the sternoclavicular joint is a rare injury and typically requires high-energy forces applied through the joint. Initial treatment is dependent on the direction of dislocation, with acute reduction indicated for posterior dislocations presenting with signs of tracheal, esophageal, or neurovascular compression. Although most patients do well with conservative treatment after the initial trauma, some can have persistent pain and scapular dyskinesia due to instability or locked dislocation of the sternoclavicular joint. Stabilization of the sternoclavicular joint with reconstruction may be indicated for those with persistent symptoms despite a trial of steroid injections and physical therapy. In this report and video, we present a figure-of-8 reconstruction technique to reduce and stabilize a posterior dislocation of the sternoclavicular joint using a gracilis autograft. Ultimately, this reconstruction technique can be performed in a safe, efficient, and reliable manner when appropriate surgical steps are followed.

As our knowledge and technology advance, the indications for elbow arthroscopy continue to grow rapidly. During this expansion, a number of new portals have been described and reported using variable nomenclature and location descriptions. Accordingly, a comprehensive review of these portals is warranted. Given the concern for potential iatrogenic injury to surrounding neurovascular structures, a discussion of these critical nerves and vessels is also timely. In this work, we review pertinent surface anatomy; portal nomenclature, locations, and utility; and review distances to the nearest structures at risk.

The field of elbow arthroscopy has evolved significantly since the procedure was first introduced more than 30 years ago. As our knowledge and understanding grows, numerous technical modifications have been made to improve the safety and efficacy of elbow arthroscopy. One of the most significant modifications is the change from the supine hanging position to the supine-suspended position with the use of a mechanical arm holder. Currently, the supine-suspended and lateral decubitus positions are the 2 most commonly used techniques. In this work, we discuss the history of the supine position, provide key points for proper patient positioning, and detail the steps of diagnostic elbow arthroscopy. It is our hope that this work will serve as an up-to-date review and summary of the most critical components of this procedure for emerging elbow arthroscopists.

In recent years, arthroscopy has gained popularity as a preferred treatment of a multitude of pathologies affecting the elbow. Since its initial description in 1985, many modifications have been made as our knowledge and technology have advanced. Currently, the majority of arthroscopic procedures are performed in either the lateral decubitus or supine suspended position. In this work, we discuss the history, patient positioning, and key steps for performing elbow arthroscopy in the lateral decubitus position. In addition to key steps, a number of strengths and limitations of this set up are discussed in detail. When properly executed, elbow arthroscopy can be performed in a safe and efficient manner with minimal risk to patients.

Capitellar osteochondritis dissecans (OCD) is one of the most common causes of elbow pain and dysfunction in adolescent athletes. It typically occurs in gymnasts and overhead throwers and presents along a wide spectrum of severity. Stable lesions can typically be treated with conservative therapy; however, those presenting with instability, fragmentation, or loose bodies generally require surgical intervention. Although there are a number of described surgical options used to treat capitellar OCD lesions, microfracture is one of the most commonly performed and well studied. Patients who are candidates for microfracture generally have favorable outcomes with high rates of return to athletic activity after postoperative rehabilitation. In this work, we present our preferred arthroscopic technique for microfracture of OCD lesions of the capitellum. This technique is most suitable for patients with unstable or fragmented OCD lesions that are less than 1 cm in diameter and do not violate the lateral-most articular margin of the capitellum.

Reconstruction of the ulnar collateral ligament (UCL) is one of the most commonly performed surgical procedures in overhead throwing athletes. Since its initial description, the procedure has undergone a number of technical modifications and advancements. This has resulted in multiple described techniques for UCL reconstruction. One of the most commonly performed UCL reconstruction methods is the docking technique. It has the advantages of minimizing injury to the flexor-pronator mass, avoiding the ulnar nerve, allowing robust graft tensioning, and reducing the amount of bone removed from the medial epicondyle compared with previously described techniques. This article provides a detailed description and video demonstration of how to perform this technique. When precise surgical steps are followed and postoperative rehabilitation appropriately progresses, this procedure has a well-documented history of reliably returning athletes to competitive throwing.
