| Femoroacetabular Impingement (FAI) Osteoplasty |
Cam or pincer morphology with activity-related groin pain, restricted hip motion, and imaging-confirmed impingement. |
Reshapes excess bone at the femoral head–neck junction and/or acetabular rim to reduce abnormal contact. |
Most appropriately selected patients show meaningful improvement in pain and hip-function scores within 6–12 months. |
Protected weight-bearing is commonly used for approximately 2–6 weeks, depending on the extent of bone work and associated procedures. Strength and return-to-sport rehabilitation often continue for 3–6 months. |
Randomized trials have shown arthroscopic treatment can provide greater short-term improvement than structured physiotherapy for symptomatic FAI. Outcomes depend strongly on diagnosis, cartilage status, correction quality, and rehabilitation. |
| Acetabular Labral Repair |
Traumatic or degenerative labral tears with persistent symptoms, especially when the labral tissue is repairable and hip stability can be preserved. |
Uses sutures or anchors to restore the labrum’s seal and improve load distribution around the hip joint. |
Patient-reported pain and function commonly improve substantially during the first 6–12 months; repair is generally favored over removal when viable tissue can be preserved. |
Weight-bearing and hip-flexion limits are frequently used for the first 2–4 weeks. Full functional recovery may require 3–6 months, with longer timelines for high-impact sports. |
Clinical studies support labral preservation when technically feasible. Results are less predictable with advanced osteoarthritis, substantial cartilage loss, dysplasia, or untreated bony impingement. |
| Synovectomy |
Inflamed or hypertrophic synovium associated with inflammatory synovitis, proliferative synovial disorders, or selected cases of pigmented villonodular synovitis/tenosynovial giant-cell tumor. |
Removes diseased synovial tissue to reduce irritation, pain, swelling, and mechanical restriction. |
Approximately 70–90% short-term symptom or function improvement has been reported in selected cohorts; the range is not universal and recurrence risk varies by the underlying disease. |
Early motion is often encouraged, while weight-bearing restrictions depend on the disease, extent of excision, cartilage condition, and any additional procedure performed. |
International hip-arthroscopy literature describes meaningful short-term improvement in carefully selected patients. Long-term surveillance may be required for proliferative synovial disease because recurrence can occur. |
| Loose-Body Removal |
Intra-articular fragments caused by trauma, osteochondral injury, degenerative disease, synovial disorders, or developmental conditions. |
Removes mobile cartilage, bone, or calcified fragments that cause catching, locking, pain, or range-of-motion limitation. |
Mechanical symptoms may improve rapidly when the loose body is the principal pain generator and the joint has limited pre-existing cartilage damage. |
Recovery is often shorter than for procedures requiring bone reshaping or cartilage restoration, although weight-bearing may be modified when an osteochondral lesion is treated at the same time. |
The best results are associated with a clearly identified mechanical loose body and limited osteoarthritis. Removing fragments does not reverse established cartilage degeneration. |
| Acetabular Chondral Repair or Microfracture |
Small, contained full-thickness cartilage defects in patients without advanced diffuse osteoarthritis. |
Stimulates marrow-derived repair tissue through controlled perforations in the subchondral bone; may be combined with labral repair or FAI correction. |
Selected patients may experience meaningful pain and function improvement over 6–12 months, but the quality and durability of repair tissue are variable. |
Partial or restricted weight-bearing is commonly required for approximately 4–8 weeks, followed by gradual strengthening. Return to impact activity is usually delayed compared with isolated labral treatment. |
Microfracture is generally reserved for small, well-contained defects. Advanced arthritis, large lesions, poor bone quality, or untreated mechanical overload reduce the likelihood of durable benefit. |
