Abstract:[Objective] To compare the clinical outcomes of total hip arthroplasty (THA) versus hip arthrodesis (HA) in the treatment ofadvanced hip tuberculosis. [Methods] A retrospective study was performed on 88 patients who received surgical treatment for advanced hiptuberculosis in our hospital from January 2017 to January 2019. According to the doctor-patient communication, 44 patients received onestageTHA, while the other 44 received HA. The documents regarding perioperative period, follow-up and auxiliary examination were com-pared between the two groups. [Results] All patients in both group had corresponding surgical procedures performed successfully withoutserious complications. The THA group proved significantly superior to the HA group in terms of operation time [(90.3±9.3) min vs (97.1±8.6) min, P<0.05], intraoperative blood loss [(206.5±60.5) ml vs (231.5±54.3) ml, P<0.05], hospital stay [(14.4±1.9) days vs (15.3±1.3) days,P<0.05] and postoperative walking time [(8.4±1.3) days vs (9.1±1.2) days, P<0.05]. The mean follow-up time lasted for (18.2±3.2) monthson an average, and there was no significant difference in the time to return to full weight-bearing activities between the two groups (P>0.05). During the follow-up, local tuberculosis recurrence was noted in 2 cases of the THA group, while 3 cases in the HA group, whichwere cured after repeated debridement and regular anti-tuberculosis therapy. Compared with those preoperatively, the Harris scores in bothgroups improved significantly, while the flexion-extension and adduction-abduction range of motions (ROMs) in the THA group significant-ly increased (P<0.05), whereas the ROMs in the HA group were lost at the last follow-up. At the latest follow-up, the THA group was signif-icantly better than the HA groups in terms of Harris score [(93.2±8.4) vs (85.6±7.4), P<0.05], flexion-extension ROM [(102.9±9.6)° vs 0°,P<0.05] and adduction-abduction ROM [(164.1±13.2)° vs 0°, P<0.05]. Regarding auxiliary examination, the leg length discrepancy in bothgroups significantly decreased at the last follow-up compared with that before surgery (P<0.05). At the corresponding time points, therewere no significant differences in auxiliary examination parameters between the two groups (P>0.05). [Conclusion] Both one-stage THAand HA do effectively treat advanced hip tuberculosis. In contrast, the THA has less iatrogenic trauma and better functional recovery over the HA.
