Background: Reconstruction using autograft remains the gold standard surgical treatment for anterior cruciate ligament (ACL) injuries. However, up to 10% to 15% of patients will suffer a graft failure in the future. Cadaveric studies have demonstrated that the addition of suture tape augmentation to ACL autograft constructs can increase graft strength and reduce elongation under cyclical loading.

Introduction: The medial patellofemoral ligament (MPFL) is the main restraining force against lateral patellar displacement in the first 20 degrees of knee flexion and is often disrupted following patellar subluxation or dislocation. MPFL reconstruction is commonly performed to restore patellar stability but requires autograft harvest with associated donor site morbidity. The aim of this study was to assess the five-year outcomes of MPFL repair performed with suture tape augmentation.

The anterior cruciate ligament (ACL) is the most commonly injured ligament in the knee, with injury usually occurring as a result of multidirectional sports. The incidence of ACL injury has continued to increase, with most patients opting for surgery to improve stability as well as permit a return to sport. Traditional methods of ACL reconstruction can achieve this but are not without their problems, including graft rupture, residual laxity, and donor-site morbidity.

Background: The anterolateral ligament (ALL) contributes to anterolateral rotational stability of the knee. Internal bracing of the anterior cruciate ligament (ACL) and ALL reinforces the ligaments and encourages natural healing by protecting both during the healing phase and supporting early mobilization.

Purpose/hypothesis: To assess the 2-year patient-reported outcomes of combined ACL repair and ALL internal brace augmentation.

The most common injury sustained to the ankle ligaments is a result of inversion of the foot. This mechanism results in injury to the anterior talofibular ligament alone or in conjunction with the calcaneofibular ligament and posterior talofibular ligament. Patients experiencing recurrent ankle sprains despite nonoperative measures often require surgical management.

The medial collateral ligament (MCL) is among the most commonly injured structures of the knee. Most cases are managed nonoperatively; however, grade III injuries and injuries associated with multiligament injuries to the knee are often managed surgically. MCL reconstruction procedures are the most widely used surgical option, but modern advancements have seen a renewed interest in ligamentous repair that avoids graft-site morbidity.

Meniscal tears are the most common indication for knee surgery. An appreciation of the limitations associated with the gold-standard inside-out meniscal repair technique has resulted in the development of newer all-inside techniques that overcome many of these issues. This paper describes, with a video illustration available online, a one-handed all-inside meniscal repair technique using the Meniscal Cinch™ II (Arthrex, Inc.

Background: Anterior cruciate ligament (ACL) reconstruction with hamstring or patellar tendon autograft has been the gold standard for the operative treatment of an ACL rupture for many years. Repair with Internal Brace Ligament Augmentation (IBLA) is a new technique that uses ultra-high strength tape (FiberTape, Arthrex, Naples, FL, USA) to bridge the ligament. This technique reinforces the ligament as a secondary stabiliser, encouraging natural healing of the ligament by protecting it during the healing phase and supporting early mobilisation.

The posterior cruciate ligament (PCL) acts as the primary restraint to posterior tibial translation of the knee. Injuries to the PCL are rare in isolation and more often are associated with multiligament injuries to the knee. Several PCL reconstruction and PCL repair techniques have been described in the literature, but no single technique has been shown to be the most superior.

The medial patellofemoral ligament (MPFL) is the main restraining force in the first 20° of flexion against lateral patellar displacement and is disrupted after patellar subluxation or dislocation. MPFL reconstruction is frequently performed when conservative management fails and the patient has recurrent patellar dislocations. However, a variety of complications have been reported in the literature with this procedure.

Injury of the acromioclavicular joint (AC joint) is one of the most common conditions affecting the shoulder girdle in athletes, particularly in contact sports. It is generally agreed that surgical management provides superior outcomes in high-grade injuries (Rockwell Grades IV-VI), with nonoperative management preferred in low-grade injuries (Grades I-II). Controversy still exists regarding the optimal treatment for Grade III injuries, with various sources reporting quicker return to activity and reduced complications with nonoperative management, but superior long-term function and satisfaction in cases managed surgically.
