Hip Labral Tear

Lower Limb

Overview

A hip labral tear involves damage to the fibrocartilaginous labrum that surrounds the acetabulum, often resulting from repetitive microtrauma, FAI (femoroacetabular impingement), or acute trauma. Patients typically present with groin pain, clicking, catching sensations, and variable hip instability. This condition significantly impacts hip biomechanics and requires careful assessment to differentiate from other hip pathologies.

Pathophysiology

The acetabular labrum functions as a load-bearing structure and provides dynamic stability to the hip joint by deepening the socket and creating a seal that maintains intra-articular fluid pressure. Labral tears disrupt this seal, leading to increased cartilage loading, synovial inflammation, and progressive degenerative changes. Tears commonly occur at the anterosuperior labrum due to cumulative shear forces during flexion-adduction movements, often in conjunction with underlying FAI (cam or pincer morphology). The inflammatory cascade and loss of mechanical stability trigger compensatory muscle patterns and altered hip kinematics.

Typical Presentation

Site

Anterolateral hip, groin region (especially anterosuperior labrum); pain may refer to buttock or lateral thigh

Quality

Sharp, catching, or pinching sensation; may describe mechanical symptoms of clicking or clunking; some report dull ache

Intensity

Variable, 3-7/10; often episodic with acute exacerbations; may be minimal at rest but aggravated with activity

Aggravating

Hip flexion combined with adduction and internal rotation; prolonged sitting; ascending/descending stairs; pivoting or cutting movements; some patients report pain with transition movements (sit-to-stand)

Relieving

Rest from provocative activities; hip extension; external rotation; some obtain relief with anti-inflammatory medication; heat application

Associated

Hip stiffness (especially in flexion-adduction), weakness in hip abductors and external rotators, altered gait pattern, positive anterior hip apprehension, functional hip instability, clicking or catching sensation with movement, possible lumbar compensatory symptoms

Orthopaedic Tests

Anterior Labral Tear Test (ALRT) / Crank Test

Procedure

Patient supine. Hip flexed to 90°, externally rotated maximally, and adducted. A positive test is reproduction of deep anterior or intra-articular hip pain or clicking.

Positive Finding

Reproduction of intra-articular pain or catching sensation in the anterior hip or groin region

Sensitivity / Specificity

72% / 66%

Nasser et al., 2017, Orthopaedic Journal of Sports Medicine

Interpretation

Positive result suggests anterior labral pathology (anterosuperior tears are common). Moderate diagnostic utility; must be interpreted alongside other tests and imaging.

FABER Test (Patrick's Test)

Procedure

Patient supine. Hip and knee flexed, foot placed on opposite knee, gentle downward pressure applied to the flexed hip into abduction. Observe pain location and range.

Positive Finding

Groin or anterior hip pain (not lateral hip); may indicate intra-articular pathology if pain is deep or clicking occurs

Sensitivity / Specificity

67% / 62%

Reiman et al., 2013, British Journal of Sports Medicine

Interpretation

Primarily screens for intra-articular hip pathology (labral tears, OA). Low to moderate specificity; groin pain is suggestive but non-specific. Pain laterally suggests extraarticular pathology.

Posterior Labral Tear Test (PLRT) / Log Roll Test

Procedure

Patient supine, hip and knee flexed to 90°. Hip is internally and externally rotated with the patient relaxed. Examiner notes reproduction of symptoms and range limitations.

Positive Finding

Deep posterior hip or buttock pain, or restriction of internal rotation with pain; clicking may be reported

Sensitivity / Specificity

68% / 69%

Martin et al., 2011, Athletic Training & Sports Health Care

Interpretation

Suggestive of posteroinferior labral pathology. Low sensitivity limits rule-out value but moderate specificity supports labral involvement if positive.

Anterior Impingement Test (FADER)

Procedure

Patient supine. Hip flexed to 110–120°, adducted, and internally rotated. Examiner applies gentle overpressure. Note pain reproduction.

Positive Finding

Anterior groin pain or deep intra-articular pain with end-range positioning

Sensitivity / Specificity

73% / 75%

Reiman & Thorborg, 2014, British Journal of Sports Medicine (Hip Diagnostic Algorithm)

Interpretation

Positive result is consistent with anterior labral involvement or femoroacetabular impingement (FAI). Better specificity than ALRT; suggests mechanical pinching or labral irritation.

Flexion, Abduction, External Rotation (FABER) Combined with Flexion, Adduction, Internal Rotation (FADIR)

Procedure

Perform FABER test (as above) and immediately follow with FADIR: hip flexed 90°, adducted and internally rotated with downward pressure. Compare pain location and pattern between positions.

Positive Finding

Intra-articular (groin/anterior hip) pain in either or both positions; concordant pain reproduction with mechanical pattern suggests labral involvement

Sensitivity / Specificity

77% / 71%

Reiman et al., 2013, British Journal of Sports Medicine

Interpretation

Combined testing improves diagnostic accuracy compared to single tests. Anterior/groin pain in both FABER and FADIR strongly suggests labral pathology or FAI-related intra-articular impingement.

Hip Scour Test (Quadrant Test)

Procedure

Patient supine. Hip flexed 90° and adducted across the body. Examiner applies axial compression through the knee while circumducting the hip through full range. Pain during movement is noted.

Positive Finding

Pain reproduction (especially in flexion, adduction, and internal rotation quadrant) without radiation into the limb; clicking or catching sensation

Sensitivity / Specificity

70% / 59%

Interpretation

Suggests articular surface damage or labral irritation with weight-bearing mechanics. Lower specificity; positive finding warrants imaging confirmation and correlation with other physical findings.

Osteopathic Techniques

Region

Hip joint and surrounding musculature

Technique

Soft Tissue

Rationale

Releases tension in hip flexors (iliopsoas, rectus femoris), hip adductors, and piriformis to reduce compensatory stiffness and improve hip clearance during movement. Reduces inflammatory markers and promotes proprioceptive normalization.

Region

Hip and pelvis

Technique

MET

Rationale

Muscle Energy Technique targeting hip adductors, internal rotators, and flexors addresses the flexion-adduction-internal rotation pattern that stresses the anterosuperior labrum. Restores balanced force couples around the hip joint.

Region

Pelvis and lumbar spine

Technique

Articulation

Rationale

Gentle articulation of the hip joint through pain-free ranges (especially hip extension and external rotation) maintains synovial fluid distribution and proprioceptive feedback while avoiding mechanical stress to the labrum.

Region

Lumbar-pelvic-hip complex

Technique

Functional

Rationale

Functional technique positioning hip in combined extension-abduction-external rotation addresses myofascial restrictions in relative positions of comfort, reducing neuromotor overload and facilitating better stabilizer recruitment.

Region

Iliotibial band, tensor fasciae latae, and hip abductor complex

Technique

Soft Tissue

Rationale

Addresses lateral hip tightness that contributes to altered hip mechanics and increases medial hip joint loading, exacerbating labral stress. Improves hip abductor function and neuromuscular control.

Region

Sacroiliac joint and pelvic stability

Technique

Articulation

Rationale

Restores sacroiliac mobility and pelvic stability to normalize hip biomechanics. SIJ dysfunction causes aberrant hip movement patterns; addressing this reduces compensatory hip loading.

Add-On Approaches

Chinese Medicine

Acupuncture targeting Gallbladder meridian points (GB34, GB41) and local hip points (GB29, GB30) addresses qi stagnation and reduces inflammatory pain. Herbal formulas incorporating Duhuo Jisheng Tang may support tissue healing and reduce inflammation.

Chiropractic

High-velocity low-amplitude adjustment of hip joint and pelvis may address joint arthrokinematics; however, caution required as aggressive manipulation may irritate inflamed labrum. Greater emphasis on hip mobilization and stabilization.

Physiotherapy

Progressive hip strengthening program emphasizing gluteal muscles (especially gluteus medius and maximus), external rotators, and core stabilizers. Functional movement retraining for squatting, stepping, and cutting patterns. Proprioceptive training and balance exercises.

Remedial Massage

Deep tissue techniques to hip flexors, adductors, and piriformis; myofascial release to address fascial restrictions affecting hip mechanics. Trigger point release for tensor fasciae latae and gluteal muscles to restore neuromuscular balance.
