Arthroscopic Decompression of a Type III Subspine Impingement

Extra-articular hip impingement refers to a variety of hip disorders causing pain and limited function in young, non-arthritic patients. Recently, there has been an increased focus on analyzing the degree of anterior inferior iliac spine (AIIS) dysmorphism and its correlation with subspine impingement (SSI), defined as abutment between a prominent distal aspect of the AIIS and the anterior aspect of the femoral head-neck junction. Arthroscopic decompression of the AIIS is recognized as an effective treatment for SSI. However, there may be some inherent risks of performing this procedure arthroscopically that require further investigation

Technique of Arthroscopically Assisted Transtrochanteric Drilling for Femoral Head Chondral Defects

Microfracture is a marrow-stimulation technique in which damaged cartilage is drilled or punched, perforating the subchondral bone and generating a blood clot within the defect that matures into fibrocartilage. Microfracture for the treatment of small cartilage defects of the hip has shown good results. Arthroscopic procedures are less invasive than open procedures and have a reduced incidence of complications such as infection or avascular necrosis of the femoral head. Furthermore, arthroscopic procedures allow for a shorter recovery time, resulting in not only lower overall treatment costs but also higher patient satisfaction. Medial and parafoveal cartilage defects of the femoral head can be challenging to effectively microfracture using standard arthroscopy portals because of the acute angles required for instrument manipulation. This report describes a technique for microfracturing these challenging areas of the femoral head using a 2.7-mm K-wire and drilling in a transtrochanteric direction using arthroscopic and imaging guidance to target the area of chondral damage

Arthroscopic Technique of Capsular Plication for the Treatment of Hip Instability

Atraumatic instability or microinstability of the hip is a recognized cause of groin pain and hip instability. Risk factors include female sex, ligamentous laxity, and borderline dysplasia. Arthroscopically, the joint may distract easily, and there may be associated ligamentum teres tears and laxity of the capsule on manual probing. The use of arthroscopic capsular plication in this cohort of patients has shown good to excellent results. Biomechanically, a capsular plication aims to create an imbrication and inferior shift of the capsule to augment the screw-home mechanism of the capsuloligamentous structures and thereby improve stability in extension and external rotation. The purpose of this article is to detail the step-by-step surgical technique of arthroscopic capsular plication, in addition to the indications, pearls, and pitfalls of the technique

Anatomic Labral Repair in the Hip Using a Knotless Tensionable Suture Anchor

To perform a proper labral repair, most surgeons use anchors to secure the labrum to the acetabular bone. We aim to describe a technique for labral repair with a knotless tensionable suture anchor. This technique uses a looped suture configuration, allowing selective tensioning of the repair to maintain the anatomic suction seal of the hip. The use of this technique is easily reproducible and reduces the surgical time compared with previous techniques

Endoscopic Pubic Symphysectomy for Recalcitrant Osteitis Pubis

Recalcitrant osteitis pubis presents a challenging problem for orthopaedic surgeons. Various surgical interventions have been described for treatment, including opening-wedge resection, symphysiodesis, and curettage. We propose that endoscopic pubic symphysectomy offers an effective method of treating such a challenging problem. This article describes in detail the technique used to perform endoscopic pubic symphysectomy, and a companion video demonstrating the procedure is included. Our experience suggests that removal of the interpubic fibrocartilaginous lamina and resection of approximately 1 cm of bone can successfully eliminate all sources of pain and dysfunction caused by the recalcitrant osteitis pubis

Anterior Tibial Tendon Side-to-Side Tenorrhaphy after Posterior Tibial Tendon Transfer: A Technique to Improve Reliability in Drop Foot after Common Peroneal Nerve Injury

Common peroneal nerve injury is present in 40% of knee dislocations, and foot drop is the principal complication. Posterior tibial tendon transfer is a viable solution to replace the function of the anterior tibial tendon (ATT) in the mid-foot. Several techniques for posterior tibial tendon transfer exist today, with variable results reported. However, adding augmentation with side-to-side tenorrhaphy of ATT to the transferred posterior tibial tendon (PTT) enhances anterior tissue balance and load sharing stress between native ATT enthesis and PTT tenodesis, allowing early rehabilitation and improving functional outcomes. Side-to-side tenorrhaphy is performed after PTT tenodesis in the lateral cuneiform to improve reliability in foot drop. This technique allows shorter immobilization time (from 6 to 2 weeks), earlier rehabilitation, sooner weight-bearing, and decreased risk of arthrofibrosis, scar formation, and muscle atrophy

Anatomic Considerations in Hamstring Tendon Harvesting for Ligament Reconstruction

Hamstring tendon autograft remains a popular graft choice for anterior cruciate ligament reconstruction. Although the technique of hamstring autograft harvest is relatively straightforward, it is critical to pay attention to several technical steps to avoid iatrogenic anatomic or neurovascular damage as well as to reduce the risk of premature amputation of the graft when using a tendon stripper. We describe a technique of hamstring autograft harvesting using only 2 anatomic references that makes it a simple and reproducible technique for surgeons, especially those in training
