Background: Lateral meniscal oblique radial tears (LMORTs) are the most common type of lateral meniscal tears and occur concomitantly with anterior cruciate ligament (ACL) tears in up to 12% of cases. Four types of LMORTs have been classified in the literature based on proximity to the meniscal root and extent of the tear. Type 1 and 2 LMORTs represent partial and complete posterior root tears less than 10 mm from the root insertion. Type 3 and 4 LMORTs are partial and complete posterior radial meniscus tears greater than 10 mm from the root insertion. Indications: Type 3 and 4 LMORTs can and should be addressed with an all-inside side-to-side repair at the time of ACL reconstruction. LMORTs that are not repaired at the time of ACL reconstruction can contribute to persistent instability and meniscal extrusion. Technique Description: Diagnostic arthroscopy is performed to evaluate the posterior aspects of both the medial and lateral meniscus. The medial leaflet is commonly flipped into the notch and scarred to ACL remnant. After identifying and isolating the medial leaflet, an arthroscopic suture passer is used to pass a suture from inferior to superior through the medial leaflet. A second suture is passed from inferior to superior through the lateral leaflet. This is used to shuttle the suture pass through the medial leaflet to the bottom of the meniscus, where it can be tied in a horizontal mattress fashion. The sutures are tied down with aide of an arthroscopic knot pusher. A second set of sutures is passed and used to shuttle a second suture that would be tied posterior to the first suture, again in a horizontal mattress fashion. This allows reduction of the fragments in apposition across the tear. Postoperatively, patients are allowed range of motion from 0° to 90° and to toe touch weightbearing for the first 4 weeks. Patients are advanced to weightbearing as tolerated at 5 weeks. Typical return to sport ranges from 6 to 9 months postoperatively. Results: Results have been published for 2-year outcomes of type 3 and 4 LMORT repairs and have demonstrated persistent improved patient-reported outcomes as well as healing rates that are greater than 80% and in some series approach nearly 100%. Discussion/Conclusion: Arthroscopic all-inside side-to-side surgical repair is a durable and reliable treatment option for patients presenting for ACL reconstruction with concomitant type 3 or 4 LMORT.

Background: Managing patients with recurrent anterior shoulder instability and glenoid bony deficiency remains a challenge. Multiple graft options, including iliac crest, distal clavicle, coracoid, and distal tibia allograft have been used. There is a growing body of evidence that supports distal tibia allograft for glenoid restoration in patients with shoulder instability due to its ability to restore the articular surface as well as the glenoid depth and curvature. Indications: Surgical indications for anterior glenoid reconstruction with distal tibia allograft combined with open capsular shift include patients with recurrent shoulder instability and glenoid bone loss. Technique Description: A deltopectoral interval is utilized and the subscapularis is split in lines with its fibers. The subscapularis and capsule are split together in a horizontal fashion and tagged together. Any prior hardware is then removed utilizing appropriate removal sets, a burr, and a broken screw set if necessary. The anterior glenoid is then prepared and the defect is measured. Bone marrow aspirate is then harvested from the proximal humerus using a vortex needle. The distal tibia allograft is then cut to size and prepared utilizing pulsed lavage, pressurized sterile carbon dioxide, and the bone marrow aspirate. The allograft is then fixed with solid stainless steel 3.5-mm cortical screws with washers. The medial, glenoid based capsular repair it completed by placing 1.8-mm knotless FiberTak anchor at the bottom of the distal tibia allograft. A free needle is utilized to place a horizontal mattress stitch from the anchor to the inferior capsule, which is then loaded onto a shuttling suture, to repair it to the anterior inferior glenoid. A knotless anchor is then placed right off the chondral margin of the humeral head, and this is used to repair both the capsule and subscapularis in the correct position by passing through both inferior and superior leaflets. This is then loaded onto the knotless anchor and reduced, which shifts the subscapularis and capsule laterally. The remainder of the subscapularis split is then closed. Patients are then placed in a sling with an abduction pillow with no shoulder range of motion for 6 weeks. They can then progress their therapy with a goal of returning to sport at 6 months. Results: Several large systemic reviews have shown that return to sport rates after anterior glenoid reconstruction range between 80% and 90%, with returning to the same level of play in the 70% range. Discussion: Anterior glenoid reconstruction utilizing distal tibia allograft combined with an open capsular shift is a durable surgical option for patients presenting with shoulder instability and glenoid bone loss.

Background: Irreparable rotator cuff tears represent approximately 12% of all presenting cuff tears, and multiple surgical techniques have been described for treatment, including allograft/bridge augmentation, debridement, partial repair, subacromial balloon, tendon transfer, and superior capsule reconstruction (SCR). SCR has demonstrated durable improvement in range of motion (ROM) and outcome scores at 2 and 5 years. Indications: Surgical indications for SCR include an irreparable tear of the supraspinatus and/or infraspinatus with a preserved or reparable subscapularis and preserved glenohumeral joint cartilage. Technique Description: Diagnostic arthroscopy is performed to identify and characterize the rotator cuff tear. Thorough debridement of the greater tuberosity is performed. Two all-suture FiberTak anchors are placed in the superior aspect of the glenoid. Two 2.6-mm FiberTak suture anchors are placed in the humeral head at the chondral margin. After measuring, the dermal allograft is cut to size with 15-mm overhang left on the far lateral edge. A 12-mm passport cannula is inserted laterally and the sutures from the glenoid and humeral head anchors are brought out through the cannula maintaining their position and orientation. The sutures are passed through the graft outside the cannula. The graft is introduced into the shoulder via the passport cannula with a back grasper. A cannula-in-cannula technique is used to tie the glenoid anchors first and then the medial row anchors. Two lateral row swivel lock anchors are used to complete a standard double row repair. Margin convergence is performed between the dermal allograft and remaining rotator cuff anterior and posterior. Postoperatively, patients are kept in a sling for 6 weeks, with no shoulder ROM. From weeks 6 to 12, patients discontinue sling and begin passive progression to active ROM. Strengthening is initiated at 12 weeks, and return-to-sport or work is at approximately 6 months. Results: Irreparable rotator cuff tears treated with arthroscopic rotator cuff repair and SCR show durable improvement in patient-reported outcomes at 2 and 5 years. Re-tear rates did not differ between athletes and non-athletes. Discussion/Conclusion: Arthroscopic rotator cuff repair with SCR is a durable and reliable surgical option for patients presenting with preserved glenohumeral joint and irreparable supraspinatus and/or infraspinatus tear.

Background: Osteochondritis dissecans (OCD) of the capitellum can be a disabling condition that typically affects adolescent, overhead athletes. To date, a variety of different surgical treatment options have been described. Indications: Surgical indications for osteochondral allograft transplantation (OCA) for capitellar OCD lesions include failure of nonsurgical management or prior surgery and unstable, full-thickness lesions of almost any size affecting both bone and cartilage. The anconeus preserving approach specifically provides wide access to nearly the entire capitellum and can be used for lesions in almost any location. Technique Description: The anconeus preserving approach for OCA utilizes the interval between the anconeus and the ulna. With the patient positioned supine and the elbow flexed on an arm table, an incision is made approximately 1 cm lateral to the olecranon and is carried down to the fascia. Electric cautery is used to dissect the interval between the ulna and the anconeus. The anconeus is elevated off the ulna and retracted laterally to expose the underlying joint capsule. An L-shaped capsulotomy is performed over the center of the capitellum, just proximal to the annular ligament of the radial head. A pin is placed into the center of the lesion, perpendicular to the capitellum. A cannulated reamer 0.5 mm smaller than the lesion is used to ream the lesion to a depth of approximately 5 mm. Depth measurements are taken at all 4 poles of the defect. About 3 cc of bone marrow aspirate harvest is then obtained from the ulna using a cannulated needle. The oscillating saw is used to cut the graft to size using the prior measurements. The bone marrow aspirate is placed onto the osseous side of the graft before the osteochondral graft is impacted into the recipient site. The capsulotomy is then closed, and the anconeus is repaired back to the ulna. Postoperatively, patients begin range of motion as soon as tolerated, initiate strengthening at 6 weeks, and initiate return-to-sport programming at 3 months. Results: Lesions treated with OCA typically demonstrate improvement in all outcome measures, including functional scores, graft incorporation, articular surface congruity, and return-to-sport. Complications and graft failure is rare. Discussion/Conclusion: OCA using an anconeus preserving approach is a reliable option for surgical management of unstable OCD lesions.
