Allocation of Anchors During Labral Repair: A Multicenter Cohort Analysis of Labral Treatment in Hip Arthroscopy.

Background: While previous studies have established several techniques for suture anchor repair of the acetabular labrum to bone during arthroscopic surgery, the current literature lacks evidence defining the appropriate number of suture anchors required to effectively restore the function of the labral tissue. Purpose/Hypothesis: To define the location and size of labral tears identified during hip arthroscopy for acetabular labral treatment in a large multicenter cohort. The secondary purpose was to differentiate the number of anchors used during arthroscopic labral repair. The hypothesis was that the location and size of the labral tear as well as the number of anchors identified would provide a range of fixation density per acetabular region and fixation method to be used as a guide in performing arthroscopic repair. Study Design: Cross-sectional study; Level of evidence, 3. Methods: We used a multicenter registry of prospectively collected hip arthroscopy cases to find patients who underwent arthroscopic labral repair by 1 of 7 orthopaedic surgeons between January 2015 and January 2017. The tear location and number of anchors used during repair were described using the clockface method, where 3 o’clock denoted the anterior extent of the tear and 9 o’clock the posterior extent, regardless of sidedness (left or right). Tear size was denoted as the number of “hours” spanned per clockface arc. Chi-square and univariate analyses of variance were performed to evaluate the data for both the entire group and among surgical centers. Results: A total of 1978 hips underwent arthroscopic treatment of the acetabular labrum; the most common tear size had a 3-hour span (n = 820; 41.5%). Of these hips, 1645 received labral repair, with most common repair location at the 12- to 3-o’clock position (n = 537; 32.6%). The surgeons varied in number of anchors per repair according to labral size (P Conclusion: Variation existed in the number of anchor implants per tear size. When labral repair involved a mean clockface arc \u3e2 hours, at least 2 anchor points were fixated

Arthroscopic Microfracture of Hip Chondral Lesions

Microfracture of hip chondral lesions has been performed for more than a decade with modified treatment principles and techniques from knee arthroscopy. This note and accompanying video review the pertinent techniques, pearls, and pitfalls of the microfracture procedure in the treatment of hip chondral lesions. After debridement of damaged chondral tissue, the size of the lesion is approximated to determine the number of microfracture holes to create. The working portal may be adjusted based on the site of the lesion. Microfracture picks of different angles are used to ensure perpendicular advancement to a depth of 3 to 4 mm in the subchondral bone. The holes are placed at a gap of approximately 3 to 4 mm. The debris is washed out to obtain open holes connecting the marrow with the articular surface. The microfracture procedure should be performed near the end of the overall procedure to secure the bleeding bone marrow within the joint and prevent washout

Basic Hip Arthroscopy: Supine Patient Positioning and Dynamic Fluoroscopic Evaluation

Hip arthroscopy serves as both a diagnostic and therapeutic tool for the management of various conditions that afflict the hip. This article reviews the basics of hip arthroscopy by demonstrating supine patient positioning, fluoroscopic evaluation of the hip under anesthesia, and sterile preparation and draping. Careful attention to detail during the operating theater setup ensures adequate access to the various compartments of the hip to facilitate the diagnosis of disease and treatment with minimally invasive arthroscopy. Furthermore, having a routine method for patient positioning and operative setup improves patient safety, as well as operative efficiency, as the operative team becomes familiar with the surgeon's standard approach to hip arthroscopy cases

Arthroscopic Treatment of Slipped Capital Femoral Epiphysis Screw Impingement and Concomitant Hip Pathology

Impingement caused by screws used for stabilization of slipped capital femoral epiphysis can be treated arthroscopically. Although troublesome screws have traditionally been removed by open techniques, arthroscopic removal can successfully be achieved. In addition to affording the patient the benefits of minimally invasive surgery, surgeons also have the ability to arthroscopically address any concomitant hip pathology responsible for pain, including femoroacetabular impingement and labral tears

High Degree of Variability in Reporting of Clinical and Patient-Reported Outcomes After Hip Arthroscopy.

BACKGROUND: Hip arthroscopy for the treatment of intra-articular pathology is a rapidly expanding field. Outcome measures should be reported to document the efficacy of arthroscopic procedures; however, the most effective outcome measures are not established. PURPOSE: To evaluate the variability in outcomes reported after hip arthroscopy and to compare the responsiveness of patient-reported outcome (PRO) instruments. STUDY DESIGN: Systematic review. METHODS: We reviewed primary hip arthroscopy literature between January 2011 and September 2016 using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Patient and study characteristics were recorded. Pre- and postoperative means and SDs of PROs were recorded from articles that used 2 or more PROs with a 1-year minimum follow-up. From this subset of articles, we compared the responsiveness between PRO instruments using the effect size, standard response mean, and relative efficiency. RESULTS: We identified 130 studies that met our inclusion/exclusion criteria, which totaled 16,970 patients (17,511 hips, mean age = 37.0 years, mean body mass index = 25.9 kg/m2). Radiographic measures were reported in 100 studies. The alpha angle and center-edge angle were the most common measures. Range of motion was reported in 81 of 130 articles. PROs were reported in 129 of 130 articles, and 21 different PRO instruments were identified. The mean number of PROs per article was 3.2, and 78% used 2 or more PROs. The most commonly used PRO was the modified Harris Hip Score, followed by the Hip Outcome Score (HOS)-Activities of Daily Living, HOS-Sport, visual analog scale, and Nonarthritic Hip Score (NAHS). The 2 most responsive PRO tools were the International Hip Outcome Tool (iHOT)-12 and the NAHS. CONCLUSION: Outcomes reporting is highly variable in the hip arthroscopy literature. More than 20 different PRO instruments have been used, which makes comparison across studies difficult. A uniform set of outcome measures would allow for clearer interpretation of the hip arthroscopy literature and offer potential conclusions from pooled data. On the basis of our comparative responsiveness results and previously reported psychometric properties of the different PRO instruments, we recommend more widespread adoption of the iHOT PROs instruments to assess hip arthroscopy outcomes

Arthroscopic Treatment of Hip Chondral Defect With Microfracture and Platelet-Rich Plasma–Infused Micronized Cartilage Allograft Augmentation

Over the past decade, arthroscopic microfracture has become increasingly popular to treat full-thickness (Outerbridge grade IV) chondral defects of the hip. This procedure borrows marrow stimulation treatment principles and techniques from knee arthroscopy, with similar mixed clinical outcomes that may be more favorable in the short term (<2 years) and poorer in the long term. Despite these varied outcomes, microfracture remains the most frequently used technique to treat small focal chondral defects because of the relative ease and cost-effectiveness of the procedure. Consequently, recent efforts have been aimed at improving or augmenting traditional microfracture to achieve more consistent success. BioCartilage (Arthrex, Naples, FL) is a biologically active scaffold containing allograft cartilage that, when combined with autologous conditioned platelet-rich plasma and placed in a defect in which microfracture was performed, may provide a superior repair that mimics native hyaline cartilage rather than the less-durable fibrocartilage that is formed with microfracture alone. This Technical Note and accompanying video review the pertinent techniques, pearls, and potential pitfalls of the microfracture procedure augmented with BioCartilage in the treatment of symptomatic full-thickness chondral defects of the hip

Arthroscopic Treatment of Bucket-Handle Labral Tear and Acetabular Fracture

Traumatic hip dislocations are associated with chondral and labral pathology as well as loose bodies that can be incarcerated in the joint. These types of injury often lead to traumatic arthritis. In some cases an osseo-labral fragment may become incarcerated in the joint that is not readily visualized preoperatively. In place of open surgery, hip arthroscopy permits a technique to remove loose bodies and repair labral tears to restore joint congruity and achieve fracture reduction and fixation

Single-Portal Arthroscopy of the Central Compartment of the Hip

Since hip arthroscopy has become a standard of orthopaedic practice, the indications have continued to expand as it has proved to be a helpful diagnostic, as well as therapeutic, tool. Access to the hip joint, however, remains challenging for the orthopaedic surgeon who does not routinely perform hip arthroscopy. We present a single-portal arthroscopic technique, showing the feasibility of single-portal arthroscopic access to the hip joint, as well as describing basic indications and instrumentation for single-portal hip arthroscopy. Single-portal hip arthroscopy is ideal for the patient who needs to undergo diagnostic hip arthroscopy or for treatment in patients with simple hip pathology (e.g., removal of loose bodies or debridement)

Arthroscopic Hip Labral Repair: The Iberian Suture Technique

Arthroscopic hip labral repair has beneficial short-term outcomes; however, debate exists regarding ideal surgical labral repair technique. This technical note presents an arthroscopic repair technique that uses intrasubstance labral suture passage to restore the chondrolabral interface. This “Iberian suture technique” allows for an anatomic repair while posing minimal risk of damage to the labral and chondral tissues
