Purpose: To analyze the arthroscopic findings and treatment results of patients with a limitation of hip motion caused by early degenerative osteoarthritis.
Materials and Methods: Retrospective analysis was performed on 13 patients who underwent arthroscopic treatment from May 2009 to March 2010, among patients with a limitation of hip motion and femoroacetabular impingement symptoms by early degenerative osteoarthritis. Head-neck offset, anteversion, and a change in the alpha angle was compared. At the final follow up, the VAS (Visual analogue scale), modified Harris hip score, and range of motion were compared.
Results: The arthroscopic findings showed diffused synovitis in all 13 cases. Among them, 9 cases were accompanied with a labral tear, and 2 cases showed a labral deformity. The VAS decreased from 7.5 preoperatively to 1.8 postoperatively and the modified Harris hip score improved from 49.3(35-60) before surgery to 90.1(85-95) after surgery. Each flexion and internal rotation improved significantly (P<0.05) from 95.2° (60-120°) to 127.7° (110-140°) and 4.6° (-5-25°) to 25.4° (15-30°), respectively.
Conclusion: This study shows that the arthroscopic treatment of femoroacetabular impingement with a limitation of the range of motion by early degenerative arthritis can be expected with an improvement in flexion and internal rotation of the hip.
