PURPOSE: To describe the outcomes of 7 cases of psoas abscess concurrent with septic arthritis of the hip treated by hip arthroscopy alone. METHODS: We retrospectively collected the data of patients who underwent arthroscopic drainage of psoas abscess concurrent with septic arthritis of the hip. Arthroscopic debridement was performed in both the central and peripheral hip joint compartments. In all cases, the iliopsoas compartment was accessed from the peripheral compartment through an anterior capsulotomy without limb traction...

Hip cartilage injuries are very common, with rates as high as 50% having been reported in some series; abnormal femoral acetabular contact can result in a full-thickness cartilage defect or labral lesion. The prevalence of labral lesions can be as high as 55%. This Technical Note describes an arthroscopic technique to reconstruct an uncontained, full-thickness, focal cartilage defect of the acetabulum, with reconstruction of the missing labrum using a gracilis allograft and use of a biological liquid scaffold for cartilage reconstruction...

The contribution of the ligamentum teres to the stabilization of the hip joint and the clinical influence of a compromised ligamentum teres are not well known. This study aimed to investigate joint stability and cartilage damage in a rabbit model by surgically inducing a complete ligamentum teres tear. Twenty adult New Zealand rabbits were used in this study. Rabbits were divided into complete ligamentum teres tear with capsulotomy (n = 9, group I) and capsulotomy only (n = 10, group II) groups. Unilateral surgery was performed on the left hip...

Most surgeons create a T-shaped or interportal capsulotomy to ensure good visibility when performing hip arthroscopy. This entails transecting the iliofemoral ligament, which may or may not be repaired at the end of the procedure. Cases of iatrogenic hip instability and pain after hip arthroscopy suggest that the iliofemoral ligament plays a crucial role in the stability of the hip joint, and thus preservation should be a goal in hip arthroscopy. We describe a minimally invasive iliofemoral ligament-sparing capsulotomy, guided by the reflected head of the rectus tendon, that can be easily repaired after arthroscopic rim trimming, labral refixation, and offset correction...

Hip arthroscopy is promising tool for assessing and treating intra-articular pathologies including labral tears, cartilage injuries, and ligamentum teres tears of the hip. Interportal capsulotomy allows for better visualization and accessibility of the arthroscope and working instruments. The hip capsule has been defined as a crucial stabilizer of the hip joint. Thus, capsular closure is recognized as an important procedure to prevent postoperative instability after hip arthroscopic surgery. Despite the routine capsular closure during hip arthroscopy, there is a small subset of patients who complain of hip pain and dysfunction after surgery most likely because of disruption of hip closure site after routine complete capsular closure with strong suture for treating hip instability...

AIMS: Several studies have reported the safety and efficacy of subcapital re-alignment for patients with slipped capital femoral epiphysis (SCFE) using surgical dislocation of the hip and an extended retinacular flap. Instability of the hip and dislocation as a consequence of this surgery has only recently gained attention. We discuss this problem with some illustrative cases. MATERIALS AND METHODS: We explored the literature on the possible pathophysiological causes and surgical steps associated with the risk of post-operative instability and articular damage...

INTRODUCTION: The application of traction in hip arthroscopy is associated with peri-operative complications. Within a therapeutic case series, patient-related factors correlating with high-traction forces during hip arthroscopy and occurring complications should be identified. MATERIALS AND METHODS: In 30 male and 38 female patients (mean age: 44.5 years), intra-operative traction forces were monitored continuously using a specialised measurement device. A multivariate analysis was employed to identify patient-related factors influencing the traction force...

BACKGROUND: Hip capsulotomy is routinely performed during arthroscopic surgery to achieve adequate exposure of the joint. Iatrogenic instability can result after hip arthroscopic surgery because of capsular insufficiency, which can be avoided with effective closure of the hip capsule. There is currently no consensus in the literature regarding the optimal quantity of sutures upon capsular closure to achieve maximal stability postoperatively. Purpose/Hypothesis: The purpose of this study was to determine the failure torques of 1-, 2-, and 3-suture constructs for hip capsular closure to resist external rotation and extension after standard anterosuperior interportal capsulotomy (12 to 3 o'clock)...

REVIEW
Joshua D Harris
The hip capsule is a highly complex anatomic structure, which influences normal hip motion and biomechanics. A dynamic stabilizing capsular contribution exists in the iliocapsularis and gluteus minimus, among other musculotendinous structures crossing the joint. Variable types and sizes of capsulotomy are necessary to sufficiently visualize and address the bony and soft tissue pathologic source of symptoms. Unrepaired capsulotomies may leave the hip significantly unstable to variable degrees. Capsular closure is a necessary part of a comprehensive arthroscopic hip preservation procedure...

Hip arthroscopy (HA) is considered to be a very difficult and demanding surgical procedure, special instruments, an image intensifier and a fracture table or hip distractor are required to access the hip joint, the most common and worldwide used HA technique is entering blindly to the central compartment with the use of fluoroscopy and continuous distraction; with the potential danger if performed in unskillful hands of labral penetrations, labral resections and scuffing of the femoral head cartilage. Our technique describes the arthroscopic management of femoroacetabular impingement (FAI), performing a preoperative planning using radiographic and anatomic landmarks to approach the anterior capsule without the use of fluoroscopy...

A 66-year-old woman had sustained crush injury 3 hours prior to her presentation to our hospital. The diagnosis was defined as lateral tibial plateau fracture of the right knee (Schatzker III). Supine position was set up and a pad was put under the affected hip. After sterilization of the surgical field the sterilized sheets were placed beneath the leg in order to be higher than the other side. A rolled sheet was put under the knee joint so that the knee joint was flexed around 30° to 40°. After the surgical field was draped the skin was incised...

Open synovectomy remains the treatment of choice for pigmented villonodular synovitis (PVNS) of the hip but has shown modest results compared with the treatment of other joints. Recent advances in hip arthroscopy permit a thorough evaluation of the joint surfaces, improved access, and decreased postoperative morbidity. We describe an arthroscopic synovectomy technique for PVNS of the hip. The use of additional arthroscopic portals and creation of a large capsulotomy enable successful visualization and extensive synovectomy of the entire synovial lining of the hip...

Pigmented villonodular synovitis (PVNS) is a benign synovial tumor of unknown etiology with a predilection for the large joints of the appendicular skeleton. The poor prognosis for patients with hip disease is partially imparted by current surgical techniques. Recent advances in hip arthroscopy technique and instrumentation may enable arthroscopic treatment for PVNS in the hip. The authors report the first case where hip arthroscopy was used to surgically excise a biopsy-confirmed local PVNS lesion in the hip...

PURPOSE: To determine the effect of different types of capsulotomies on hip rotational biomechanical characteristics. METHODS: Seven fresh-frozen cadaveric hip specimens were thawed and dissected, leaving the hip capsule and labrum intact. The femur was transected and potted, and each specimen was placed in a custom loading apparatus that allowed for adjustment of flexion, extension, and axial rotation of the femur. Six reflective infrared markers were attached to the specimens to track the motion of the femoral head with respect to the acetabulum in real time, and external rotation was produced by applying a torque of 10 Nm to the hip specimens...

PURPOSE: Knowledge of the effect of hip pathologies on hip biomechanics is important to the understanding of the development of osteoarthritis, and the contribution of the labrum to hip joint stability has had limited study. The purpose of this study was to evaluate the effect of labral injury to stability of the femoral head in the acetabular socket. METHODS: Ten cadaver hip specimens were tested using a robotic system under four different loading conditions: axial loading (80 N) along the femoral axis and axial loading (80 N) combined with either anterior, posterior or lateral loading (60 N)...
