Restraint of the tibia from external rotation relies heavily on the popliteus tendon's function. Injuries to the posterolateral corner frequently include damage to it. Nonetheless, injury to the structure is infrequent, typically occurring alongside other parts of the posterolateral corner. This technical note elucidates the open anatomic reconstruction procedure for the popliteus tendon. Although several techniques are known, this approach has received biomechanical validation and proven effective in achieving good outcomes. Fetuin Maximizing patient results necessitates an early rehabilitation protocol that prioritizes protected range of motion, edema control, quadriceps strengthening, and pain management.

There are infrequent cases of medial and lateral meniscus posterior horn root tears occurring in tandem. The scientific literature addressing the simultaneous repair of medial and lateral meniscus root tears in the context of ACL reconstruction remains confined. We explore the management strategies for concomitant medial meniscus posterior horn root tear (MMPHRT), lateral meniscus posterior horn root tear (LMPHRT), and anterior cruciate ligament (ACL) tear. Fetuin ACL reconstruction procedures now incorporate a surgical technique that addresses both the medial and lateral meniscus posterior horn root repairs. Fetuin We clarify the order of the repair process, thereby avoiding tunnel coalescence.

Even after various modifications, the Latarjet procedure maintains its position as the most popular choice for treating recurrent anterior shoulder instability accompanied by glenoid bone loss. The graft's resorption, whether partial or complete, often occurs, which could lead to the implant being more noticeable and the risk of the front soft tissues being compressed. To address the technical difficulties and associated health risks of metallic implants, a coracoid and conjoint tendon transfer with Cerclage tape suture, using a mini-open approach, is proposed as an alternative to the Latarjet procedure, which is typically conducted with metal screws and plates.

Numerous posterior cruciate ligament (PCL) reconstruction techniques have been presented, but residual laxity continues to represent a significant clinical challenge. To forestall graft elongation during ligament reconstruction, augmenting with sutures or tapes is a rising trend, but this entails higher financial burdens due to implant costs and potential concerns about stress shielding if the tension isn't equally distributed across the augment and graft. This paper proposes a sutureless augmentation method for allograft posterior cruciate ligament (PCL) reconstructions, achieving uniform tension of both graft and augmentation using a sheath-and-screw configuration without requiring additional fixation implants.

The ongoing refinement of rotator cuff repair techniques centers around the creation of a tension-free, stable, and biologically sound construct. Varied surgical approaches are frequently debated, lacking a single, established, gold-standard surgical procedure. A new arthroscopic rotator cuff repair approach, distinguished by two critical components, is presented. A transosseous equivalent suture bridge technique, incorporating triple-loaded medial anchors and knotless lateral anchors, was our initial approach. The second component of the procedure was the introduction of 2-strand and 3-strand sutures into the tear of the rotator cuff, followed by the precise tightening of medial knots. Six passes through the tendon are executed, each composed of 1, 2, 3, 3, 2, and 1 strands respectively. To limit the number of passes through the tendon and the overall amount of medial knots, this method was adopted. Our technique preserves the well-established biomechanical benefits similar to a double-row repair, such as reduced gap formation and expanded coverage area. Particularly, by minimizing medial knots and optimizing suture placement, the potential for decreased cuff strangulation and a more favorable biological environment for tendon healing may be realized. We believe that this procedure will produce a decrease in retear rates, maintaining immediate stability, and, as a result, improving clinical performance.

Hip capsulotomy is performed in arthroscopic hip procedures to allow for a clear view of the joint and adequate instrument access. The iliofemoral ligament, a crucial component of the hip capsule, plays a vital role in stabilizing the hip joint. Patients who have a capsulotomy without subsequent repair may suffer from hip pain and instability, significantly increasing the probability of needing revision hip arthroscopy. Hence, the imperative of re-establishing a watertight capsule closure is vital for revitalizing natural biomechanics and realizing the expected outcomes of the operation. Despite the suitability of a primary repair or plication in most cases, a capsule reconstruction procedure may be unavoidable when the quantity of tissue available is insufficient, often stemming from capsular insufficiency after an initial index surgical procedure. In cases of iatrogenic hip instability, this Technical Note outlines the authors' current arthroscopic hip capsular reconstruction approach. The technique, utilizing the indirect head of the rectus femoris tendon, is detailed along with its advantages, disadvantages, technical considerations, and potential pitfalls.

Reconstruction for chronic patellar instability in patients with open physes must carefully consider the potential for femoral growth plate injury due to the close association of the growth plate with the femoral origin of the medial patellofemoral ligament. Patellar tunnel procedures in children and adolescents pose a higher risk of fracture because the patella is, comparatively, smaller than in adults. Mimicking the normal anatomy of the medial patellofemoral complex (MPFC) necessitates reconstruction of both the medial quadriceps tendon femoral ligament (MQTFL) and the MPFL, thereby recreating the complex's characteristic fan shape, which has a broad anterior attachment to the patella and quadriceps tendon (QT). A reproducible, safe, simple, and cost-effective surgical technique for managing chronic patellar instability in patients with open physis is described in this article, focusing on MPFC reconstruction using a double-bundle QT autograft.

Quadriceps tendon rupture, a significantly impactful injury, has been treated traditionally via the creation of bone tunnels and knot-tying. The persistent weakness and gap formation in repairs has prompted recent innovations involving suture anchors and knotless technology. Even with these advancements, the clinical consequences of these repairs remain inconsistently positive. Using a pre-tied, high-tension knotted suture construct, a technique enabling re-tensioning of a quadriceps repair is detailed.

The management of recurrent anterior shoulder instability, complicated by glenoid bone loss and deficient shoulder capsule, represents a formidable hurdle for orthopaedic surgeons. Various surgical approaches, as documented in the literature, yield differing degrees of success, with the great majority of described techniques involving open procedures. We detail a comprehensive arthroscopic approach to anterior capsule reconstruction, employing an acellular human dermal allograft patch, alongside an anatomical glenoid reconstruction using a distal tibial allograft, performed in the lateral decubitus posture. Upon determining irreparable capsular insufficiency post-glenoid reconstruction, an acellular human dermal graft patch is prepared and arthroscopically implanted within the shoulder joint. The graft is then anchored to both glenoid and humerus using suture anchors.
