Labral Tear

Teres minor denervation (TMD) has gained increasing attention in recent years, particularly with the advent of magnetic resonance imaging (MRI). The potential association between TMD and shoulder instability or rotator cuff tear remains a subject of interest in the orthopedic community. In this retrospective and cross-sectional study, authors aim to investigate the potential association between TMD and shoulder instability or rotator cuff tears. Authors retrospectively analyzed MRI findings from 105 patients with TMD, focusing on rotator cuff pathologies, posterior labrocapsular complex (PLCC) tears, and posteroinferior glenohumeral joint capsule alterations...

BACKGROUND: Both gluteal and labral tears are common sources of hip pain, but no studies have evaluated how concomitant arthroscopic labral repair and correction of femoroacetabular impingement syndrome (FAIS) affect outcomes after endoscopic gluteus/minimus repair. PURPOSE: (1) To compare patient-reported outcomes (PROs) and clinically significant outcomes achievements between patients who underwent endoscopic gluteus medius/minimus and arthroscopic hip labral repair with correction of FAIS versus endoscopic gluteus medius/minimus repair without labral repair and (2) to define threshold scores required to achieve the minimal clinically important difference (MCID) and the Patient Acceptable Symptom State (PASS) for the Hip Outcome Score-Activities of Daily Living, Hip Outcome Score-Sports Specific, modified Harris Hip Score (mHHS), 12-item international Hip Outcome Tool, and visual analog scale for pain in these patients...

BACKGROUND: In the setting of femoroacetabular impingement (FAI), decompression osteoplasties reconcile deleterious loading patterns caused by cam and pincer lesions. However, native variations of spinopelvic sagittal alignment may continue to perpetuate detrimental effects on the labrum, chondrolabral junction, and articular cartilage after hip arthroscopy. PURPOSE: To evaluate the effect of pelvic incidence (PI) on postoperative outcomes after hip arthroscopy for acetabular labral tears in the setting of FAI...

Appropriate labral management is one of many procedures during hip arthroscopy that affect postoperative outcomes and revision rates. Both primary labral repair and reconstruction have been shown to have superior clinical and functional outcomes compared to labral debridement when treating unstable labral tears. Arthroscopic labral reconstruction is one of the most powerful techniques in the arsenal of complex hip preservation surgeons, and while often reserved for the revision setting, when the native labrum is irreparable, a primary reconstruction may be indicated when the only alternatives are selective labral debridement or a sub-optimal repair...

Femoroacetabular impingement (FAI) syndrome is a common cause of hip and groin pain in young individuals. FAI syndrome is a triad of signs, symptoms, and imaging findings. Necessary but not sufficient for the diagnosis of FAI syndrome is the presence of cam and/or pincer morphology of the hip. However, pathological thresholds for cam and pincer morphologies are not well-established. Management of FAI syndrome is typically through either physiotherapist-led therapy or surgical intervention. Physiotherapist-led management involves exercises aimed to optimise movement patterns of the hip and pelvis to prevent impingement from occurring, activity modification and analgesia, whereas surgical management involves arthroscopic resection of the cam/pincer morphology and treatment of concomitant soft tissue pathologies such as labral tears, cartilage lesions or ligamentum teres tears...

PURPOSE: To evaluate the reliability of the "perfect-circle" methodology for measurement of glenoid bone loss with magnetic resonance imaging (MRI) in patients with posterior glenohumeral instability. METHODS: A prospective chart review was performed on patients who underwent isolated arthroscopic posterior labral repairs in our institution's electronic medical records between January 1, 2021, and June 30, 2021. Inclusion criteria included isolated posterior shoulder instability with posterior labral repair and corroborated tears on MRI...

BACKGROUND: Previous biomechanical studies have identified capsular closure, labral repair or reconstruction, and osteochondroplasty as important surgical interventions to improve hip stability. PURPOSE: To investigate the outcome metrics used to quantify hip stability and assess and measure the relative contributions of the labrum, capsule, and bone to hip stability through a quantitative analysis. STUDY DESIGN: Systematic review and meta-analysis; Level of evidence, 4...

BACKGROUND: Humans have unique characteristics making us the only primate that can throw well while most other primates throw predominately underhand with poor speed and accuracy. The purpose of this study is to illuminate the uniquely human characteristics that allow us to throw so well. When treating an injury such as a labral tear or capsule tear, this study hopes the reader can gain a better understanding of the issues that lead to the tear and those that may determine the success of treatment besides the actual repair...

PURPOSE: The purpose of this study was to investigate a novel posterior intra-articular hip injection approach while discussing the clinical pearls for methodology, accuracy, and associated adverse events. The goal was to investigate if this approach could potentially be used in those where the typical anterior access would be challenging. MATERIALS AND METHODS: 10 adults (age > 18 years) who were referred to a tertiary outpatient clinic for hip injection due to hip osteoarthritis or femoral acetabular impingement with labral tearing to a single academic sports medicine clinic...

PURPOSE: To evaluate the radiographic and clinical outcomes when rerouting a pathologic biceps during arthroscopic rotator cuff repair by comparing it with concomitant subpectoral biceps tenodesis (SPBT). METHODS: This retrospective, historical cohort study was conducted with patients who underwent an arthroscopic repair of a full-thickness rotator cuff tear, with intraoperative confirmation of biceps pathology including partial tears, subluxation, pulley lesions, or type II SLAP lesions...

Acromioclavicular (AC) joint dislocations frequently co-occur with intra-articular glenohumeral pathologies. Few comprehensive studies have focused on labral tears specifically associated with AC joint trauma. This systematic review will address this gap. A comprehensive electronic search was conducted across PubMed, Cochrane Library, and Google Scholar (pages 1-20) spanning from 1976 to May 19, 2023. Seven studies met the inclusion criteria for this systematic review, consisting of three retrospective studies and four case series...

OBJECTIVE: To determine differences in prevalence and diagnostic accuracy of MRI findings between asymptomatic athletes and athletes with longstanding groin pain. MATERIALS AND METHODS: One hundred twenty-three adult male athletes were approached with 85 consecutive athletes recruited. Group 1 (symptomatic, n = 34) athletes referred for longstanding groin pain (insidious onset, > 3 weeks duration). Group 2 (control, n = 51) athletes referred for injuries remote from the pelvis and no groin pain in the last 12 weeks...

The hip is a uniquely constrained joint with critical static stability provided by the labrum, capsule and capsular ligaments, and ligamentum teres. The labrum is a fibrocartilaginous structure along the acetabular rim that encircles most of the femoral head. Labral tears are localized based on the clock-face method, which determines the extent of the tear while providing consistent terminology for reporting. Normal labral variants can mimic labral disease and can be differentiated by assessment of thickness or width, shape, borders, location, and associated abnormalities...

Hip acetabular labrum plays a chondroprotective role by maintaining stability, providing a suction seal, and contributing to load distribution. In symptomatic patients without osteoarthritis, arthroscopic labral repair has strong clinical and biomechanical data to support its use. For irreparable tears, the labrum should be reconstructed. Biomechanically, labral reconstruction does not demonstrate superiority when compared to labral repair or the intact native labrum state. However, it is superior to labral excision...

Not all acetabular labral tears, tissue quality, and size are the same. There is still a role for selective debridement of the acetabular labrum when stable, functional labral tissue remains. An unstable labrum that appears very different than the rest of the labrum is an easy target for repair. Tears requiring resection require graft augmentation or reconstruction.

Gluteus medius and minimus tendon pathology is a common cause of lateral hip pain. In patients that are dissatisfied with their hip condition following non-surgical treatment, gluteal repair has demonstrated excellent short-, mid-, and now recently, long-term subjective patient-reported and objective clinician-measured outcomes. In patients with peritrochanteric hip pain, the proportion of their overall hip pain may be influenced by the hip joint due to conditions like Femoroacetabular Impingement Syndrome (FAIS), acetabular dysplasia, labral tears, and arthritis...

BACKGROUND: Wheelchair basketball (WCB) is a popular para-sport adapted for athletes with physical disabilities. Shoulder injuries are commonly reported among WCB athletes. However, the understanding of the specific patterns and characteristics of shoulder injuries in WCB players is currently limited, and there is a lack of comprehensive literature available on this subject. OBJECTIVES: To investigate the spectrum of pathologies observed in elite wheelchair basketball (WCB) athletes referred for MRI evaluation of symptomatic injuries of the shoulder...

In the setting of femoroacetabular impingement of the hip joint, paralabral cysts are well-documented sequelae. These cysts are typically associated with labral tears caused by CAM and/or pincer-type bony lesions. Synovial fluid extravasation through a tear in the labrum, similar to a popliteus cyst, leads to formation of a capsular-based cyst that is usually self-limiting. Few documented cases of these cysts causing compression of nearby neurovascular structures exist. There are several studies documenting arthroscopic decompression of these cysts, but none reporting compression of the femoral vein by a paralabral cyst resulting in deep vein thrombosis...

BACKGROUND: The alpha angle has been widely used in the assessment of cam-type of impingement, but recent studies have shown that this angle may also be high in asymptomatic patients. The aim of this study is to report the prevalence of cam-type morphology in asymptomatic volunteers and explore its correlation with hip clinical and radiological parameters. METHODS: This single-centre prospective study included 48 asymptomatic male volunteers (96 hips). All candidates fulfilled the inclusion and exclusion criteria...

Transforming the orthopedic landscape, hip arthroscopy pioneers a minimally invasive surgical approach for diagnosing and addressing hip pathologies. With its origins dating back to Burman's 1931 cadaveric study, this groundbreaking technique gained clinical relevance in 1939 through Takagi's report. However, the 1980s marked the actual emergence of hip arthroscopy for treating a wide range of hip disorders. Now, a staple in modern orthopedics, hip arthroscopy empowers patients with previously undiagnosed and untreated hip conditions, enabling them to obtain relief and reclaim their lives...
