Objective:To?evaluate?the clinical?efficacy of total hip arthroplasty in patients with residual poliomyelitis.Methods:Between January 2008 and May 2018,13 THAs were performed in 13 patients with Residual Poliomyelitis,The Harris score，SF-12 score,UCLA activity score and radiological images were recorded and compared before surgery and at the last?follow-up.Result:There was no loss of follow-up,?the mean?follow-up?was?5.6 years.The?range of?abduction?motion?of hip joint was（27.69±12.01）° before surgery and （38.46±8.75）° at final follow-up,?the?difference?was statistically?significan（P<0.05）,however,there?was no?significant?difference?in the the?range of?flexion?motion?of hip joint preoperatively?and?at the?time?of the?latest follow-up?（P＞0.05）；The mean Harris hip score significantly improved from（51.46±14.96) preoperatively to（84.15±6.07）at the latest follow- up（P<0.05）;The mean UCLA activity score significantly increased from（2.62±0.96）preoperatively to（6.08±1.26）at the latest follow- up（P<0.005）;The mean SF-12 score physical component summary （PCS） and mental component summary （MCS）scores noteworthily improved from （25.69±5.59） and （42.15±7.32） to （54.08±5.09） and （51.54±5.29） respectively （P<0.05）.Imaging examination?showed that no?complications?such as?dislocation,?prosthesis?loosening or sinking?happened. Conclusion:THA can improve joint function and life quality of patients with residual poliomyelitis,proper perioperative Evaluation,surgical?treatment and ?scientific postoperative?functional?exercise will allow ?patients with residual poliomyelitis to obtain a better clinical?efficacy.
