Endoscopic Proximal Hamstring Tendon Repair for Nonretracted Tears: An Anatomic Approach and Repair Technique

Proximal hamstring injuries are common, and open surgical repair with suture anchors has been the gold standard when surgical intervention is warranted. Endoscopic techniques offer the opportunity of surgical repair with smaller incisions to limit complications and expedite rehabilitation. The purpose of this technique guide is to describe a modified endoscopic technique that allows a safe and anatomic repair of proximal hamstring injuries. The patient is positioned prone with the feet at the head of the bed, table in reverse Trendelenburg, and knees flexed to 90°. Four portals are used, 3 in horizontal alignment within the gluteal fold and 1 directly superior to the ischial tuberosity. The sciatic nerve is identified, dissected, and mobilized away from the operative field. Retraction sutures help retract the gluteus maximus and further protect the sciatic nerve. Dissection is within the interval between the conjoint and semimembranosus tendons. The tendons are freed and mobilized, the ischial tuberosity is decorticated, and an anatomic repair is performed via 4 suture anchors, 2 at each tendon footprint. Advancements in arthroscopy have permitted adequate visualization and exposure of the hamstring footprint, thus allowing for an anatomic repair with increased protection of the sciatic nerve and decreased resources and cost

Improved Arthroscopic Visualization of Peripheral Compartment

Femoroacetabular impingement is a recognized cause of hip pain and motion restrictions. Advancements in hip arthroscopy have allowed surgeons the ability to treat this condition more effectively. However, the learning curve is steep for osteochondroplasty of the femoral head-neck junction in the peripheral compartment. Therefore we present a reproducible technique that allows improved visualization of the peripheral compartment and treatment of the cam lesion with hip arthroscopy. Our technique uses the anterior portal as a viewing portal, a distal anterolateral accessory portal as a working portal, and the anterolateral portal for soft-tissue retraction

Capsular Suspension Technique for Hip Arthroscopy

Hip arthroscopy has recently become a common procedure to treat central and peripheral hip pathology. Capsulotomies are necessary in these procedures, and negotiating adequate visualization, as well as capsular preservation, is a challenge. We describe a capsular suspension technique that allows for adequate visualization of the central and peripheral compartments while facilitating preservation of the native hip capsule. This technique eliminates the need for additional personnel for retraction, potentially decreases iatrogenic hip injury, eliminates the need for excessive capsular debridement, and allows for capsular closure under minimal tension

Capsular Plication for Treatment of Iatrogenic Hip Instability

The most commonly reported reasons for persistent hip pain after hip arthroscopy are residual femoroacetabular impingement, dysplasia and dysplasia variants, or extra-articular impingement. There are some cases in which the underlying osseous pathomorphology has been appropriately treated, and the cause of persistent hip pain can be soft-tissue injuries such as chondrolabral tears or capsular abnormalities. Capsular defects after hip arthroscopy may suggest an alteration of the biomechanical properties of the iliofemoral ligament and lead to iatrogenically induced hip instability. There are a growing number of biomechanical and clinical studies showing the importance of capsular management during hip arthroscopy. We describe the workup, examination under anesthesia, diagnostic arthroscopy, and technique of capsular plication for iatrogenic instability of the hip

Diagnosis, Evaluation, and Endoscopic Repair of Partial Articular Gluteus Tendon Avulsion

In addition to trochanteric bursitis, gluteus medius and minimus tears (GMMTs) can be a common source of insidious lateral hip pain and dysfunction. Partial-thickness GMMTs are much more common than full-thickness GMMTs but are frequently overlooked by both radiologists and orthopaedic surgeons. GMMTs are commonly identified on magnetic resonance imaging ordered for lateral hip pain unresponsive to conservative management. Imaging can show that high-grade partial articular gluteus tendon avulsion (PAGTA) can occur as either an isolated gluteus medius tear, an isolated gluteus minimus tear, or a combined GMMT. We describe how to identify PAGTA injuries with intraoperative assessment and identification of the interval between the gluteus medius and minimus tendons to allow access to the PAGTA without violating the bursal side of the tendon. PAGTAs can be repaired arthroscopically by single- or double-row suture anchor fixation depending on the size of the tear. The purpose of this article is to guide orthopaedic surgeons in the recognition of PAGTA with magnetic resonance imaging and dynamic examination to allow for accurate repair of GMMTs
