Study Design: prospective non-randomized clinical study. Background Context:Diagnosis and treatment of intra-articular hip problems in young patients present a challenge. Historically, there have been limited diagnostic and treatment options available for diseases that affect the cartilage, bone or synovium in the young hip joint.Labral tears, degenerative disease, articular injures, osteonecrosis, synovial abnormalities, ligamentumteres rupture, femoroacetular impingement, instability and septic hip are some of the conditions that could now be treated by hip arthroscopy. Objective:This study will evaluate the effectiveness of hip arthroscopy in diagnosis and treatment of variable hip pathology such as: Labral tears, degenerative disease, articular injures, osteonecrosis, synovial abnormalities, ligamentumteres rupture, femoroacetular impingement. Patients And Methods: Thirty painful hips undergone hip arthroscopy with minimum 6 months follow up. 28 cases of femoroacetabular impingement (FAI) and two cases of post-traumatic loose body removal.9 cases of femoroacetabular impingement were cam impingement, 7 cases were pincer impingement and 12 cases were mixed impingement. Among our 28 cases of FAI we have found labral pathology in 20 cases, 9 cases of labral pathology managed by labral repair by anchor sutures and rest were managed by debridment. We used modified harris hip score (mHHS) and Non-arthritic hip score (NAHS) to evaluate our results. Results: A significant improvement was detectedin post-operative hip pain in all cases. Post-operative range of motion was improved. Conclusion: Hip arthroscopy is a reliable technique to treat traumatic and non-traumatic hip pathology.
