Objective To investigate the clinical effect of hip arthroscopic surgery for cam-type femoroacetabular impingememt( FAI). Methods Twenty patients with cam-type femoroacetabular impingememt undergoing hip arthroscopic surgery were selected as research objects. All the patients were definitely diagnosed by physical examination and X-ray. All the patients underwent fermoroplasty under hip arthroscopy. The patients were followed up at 1,3,6,12 months after surgery. The following parameters of preoperative and on final follow up were compared including the range of flexion,the range of internal rotation in a position of 90° flexion,α angle,VAS score,Harris score and postoperative complications. Results 9 patients( 45. 0%) suffered from acetabular labrum injury;. 17 patients( 85. 0%) suffered acetabular cartilage injury,including 14 cases of OuterbridgeⅠ ~ Ⅲ and 3 cases of OuterbridgeⅣ. The incisions were all healed by first intention,but 1 patient had scrotum swelling,2 patients had numbness on the lateral thigh,and the symptom disappeared without treatment. All the patients were followed up for 13 ~ 32 months( mean,21. 4 months). At the final follow up,impingememt tests were negative,the range of flexion increased compared with preoperative,the range of internal rotation in a position of 90° flexion increased compared to that of the preoperation,the differences had statistically significant( P 0. 01). Compared with preoperative,the α angle decreased,the VAS score decreased compared to that of the preoperation and the difference had statistically significant( P 0. 01). Conclusion The clinical effect of hip arthroscopic surgery for cam-type femoroacetabular impingememt is satisfactory,which can restore the normal curvature of the femoral head neck,effectively relieve the pains,and improve the activity and the function of hip joints.
