Meniscus root injuries lead to increased tibiofemoral contact pressures and rapid progression of osteoarthritis. Early recognition and treatment with a meniscal root repair can restore biomechanics and help preserve the joint. The transtibial pullout repair and suture anchor repair are the most commonly used techniques to achieve anatomic fixation of the meniscal root. Still, each method presents distinct advantages and disadvantages. This Technical Note aims to describe a vastly simplified, more efficient, and reproducible posterior lateral meniscal root repair using a retensionable knotless all-suture anchor.

The ulnocarpal ligament complex (UCLC), consisting of the ulnotriquetral, ulnolunate, and ulnocapitate ligaments, plays a pivotal role in maintaining ulnocarpal joint stability and is closely linked to the palmar radioulnar ligament (PRUL), preventing dorsal ulnar translation. Often, tears in the PRUL and UCLC coincide with lunotriquetral interosseous ligament (LTIL) tears as the result of their strong anatomical connections. Biomechanical studies have demonstrated that ulnar-shortening osteotomy enhances stability in the distal radioulnar joint, lunotriquetral joint, and UCLC by tightening the ligaments and capsules. Our technique aims to replicate the effects of ulnar-shortening osteotomy by plicating the volar triangular fibrocartilage complex (TFCC) and capsule, addressing combined TFCC, UCLC, and LTIL pathologies with a single-strand suture approach. Although surgical treatments exist for ulnotriquetral and LTIL tears, addressing concurrent PRUL or palmar TFCC tears has remained a challenge. This article presents a simple technique for managing these complex ulnar wrist pathologies.

The optimal treatment for patients diagnosed with isolated supraspinatus irreparable rotator cuff tears continues to be a subject of debate. Joint-preserving methods, including partial repair, superior capsule reconstruction, balloon spacers, and tendon transfer, have been introduced. Among these options, the middle trapezius tendon (MTT) transfer has garnered attention for its potential to replace the irreparable portion of the supraspinatus tendon and provide dynamic stability to the joint. Although some reports have highlighted promising clinical outcomes of MTT, there remains a dearth of literature regarding the techniques and methods involved in the surgical procedure. This Technical Note introduces an arthroscopic-assisted technique for MTT transfer using an Achilles tendon allograft for patients diagnosed with isolated supraspinatus irreparable rotator cuff tears in lateral decubitus.

Revision of anterior cruciate ligament reconstruction (ACL-R) presents many challenges that are not encountered in the primary setting and, therefore, requires thorough preoperative planning. Recently, there has been growing evidence showing that combining the anterolateral ligament (ALL) reconstruction with ACL-R revision reduces the risk of postoperative ACL rupture and meniscal tears, and therefore, the ALL reconstruction becomes essential to a complex ACL revision. The technique that we describe is mainly used in the setting of complex ACL revision with extensive tunnel osteolysis associated with rotational instability of the knee. This article presents a technique for a one-stage complex ACL-R revision combined with ALL reconstruction using an Achilles tendon allograft with a bone plug.

The hip capsule is the primary stabilizer of the hip joint. At the time of hip arthroscopy, the capsule is disrupted to obtain intra-articular access and proper joint visualization. With the number of patients undergoing primary and revision hip arthroscopy continuing to increase, it is not uncommon for surgeons to encounter patients with iatrogenic capsular deficiency from prior hip arthroscopy. In cases where substantial capsular defects beyond the scope of capsular repair are visualized, reconstruction may be required to obtain satisfactory closure and restore hip stability. We present a step-by-step workflow for efficient hip capsular reconstruction with rectus overlay while allowing for facile incorporation of other revision procedures such as labral repair and femoral osteochondroplasty.

Injuries of the posterior root of the medial meniscus can be accompanied by damage to the anterior cruciate ligament or often occur independently in cases of degenerative meniscal injury in older individuals. Anchor suture repair can achieve favorable biomechanical effects and clinical outcomes. However, anchor placement is technically challenging and requires a posterior medial approach, which increases the risk of iatrogenic injury. To address these issues, we have utilized the reverse anchor technique to repair the posterior root of the medial meniscus. This technique offers advantages such as reduced surgical time, simplified operation, and reduced risk of the “bungee effect” and iatrogenic injury.

Advancements in rotator cuff tear repair have led to innovative techniques for complex cases. In this article, we introduce the “shoe shop” lacing technique, a knotless, side-to-side, and tendon-to-bone suture method augmented with the long head of the biceps tendon (LHBT) for anterior margin–deficient massive rotator cuff tears. This approach offers simplicity, durability, and potential advantages in biomechanics. The LHBT integration and knotless sutures make it a promising solution for challenging tear patterns. This technique provides an attractive option for arthroscopic repair, improving outcomes in cases where anterior cable reinforcement is essential.

This work contains a description of the modified Henning operation. This technique can be proven especially useful in difficult cases of damaged meniscus (complex injuries). It consists of three stages: stable suturing of the meniscus, placement of the graft from the iliotibial band on the meniscus, and covering the graft with a collagen membrane. Stitching the meniscus provides initial stabilization, the graft from the iliotibial band provides scaffolding for the reconstructed tissue, and the collagen membrane provides biological stimulation for healing.
