Clinical outcomes of total hip arthroplasty for treatment of end-stage hip joint with pigmented villonodular synovitis / 局解手术学杂志

ABSTRACT

Objective To study the clinical efficacy of total hip arthroplasty for treatment of end-stage hip with pigmented villonodular synovitis(PVNS).Methods From January 2000 to March 2015,a total of 34 patients with hip PVNS were treated by total hip arthroplasty (THA) combined with synovectomy.Pelvic X-ray,CT and MRI examinations were performed before the surgery,and Harris hip joint function score was performed before and after surgery.Systematic rehabilitation training was performed after the operation,and the hip joint X-ray films were regularly reviewed.Results All the 34 patients were reviewed and observed for an average of 5.2 years (ranged from 1.5 to 7 years).The position of the prosthesis was good and the motion of the joint was satisfactory.The mean preoperative Harris hip scores improved from (45.0 ± 6.4) perioperatively to (90.2 ± 3.2) postoperatively,with statistically significant difference (t =0.468,P ＜ 0.05).None of the patients had clinical or radiographic evidence of recurrent PVNS.Conclusion Total hip arthroplasty combined with synovectomy is an effective therapeutic choice for end-stage hip with pigmented villonodular synovitis,which can improve the clinical results and prevent the disease recurrence.
