Background: This study aimed to propose a classification of acetabular defects in advanced-stage hip tuberculosis based on preoperative radiographs and intraoperative evaluation, thereby providing options for reconstructing each type of defect in hip arthroplasty. Materials and Methods: We conducted a prospective study with 45 patients with active hip tuberculosis at stage IV who were treated with a total hip replacement strategy. We collected the patients’ acetabular defect data from preoperative radiographs and intraoperative observations. The defects were classified into types based on defect severity and reconstructive complexity. The hip replacement outcomes were evaluated at least 12 months after the operation. Results: The classification system includes three types: type I: localized or extensive defects inside the acetabulum, not affecting the acetabular rim, medial wall, or columns. Type II: extensive defects inside the acetabulum, affecting the acetabular rim or (and) medial wall. Type III: extensive defects inside the acetabulum, causing the medial wall and the acetabular column to lose function. Each type has a corresponding reconstruction. The outcome includes that 41/45 patients had excellent results;3/45 patients had good results. The patients had good results due to nerve and muscle damage caused by tuberculosis not related to the acetabular defects. Conclusion: This is a simple, practical classification system of acetabular defects in hip tuberculosis. The outcome of hip reconstruction using this classification was excellent without any cases of dislocation or protrusion.

Background: Treatment of hip disorders during active hip tuberculosis has long been a controversial issue. Some authors have reported performing hip replacement with different strategies with very good outcomes. This study aimed to describe the surgical outcomes and necessary conditions for total hip replacement in active hip tuberculosis. Methods: We conducted a quasi-experimental study. The study enrolled 40 patients with 42 active tuberculosis hips at stage IV treated by total hip replacement from October 2016 to December 2019 at the National Lung Hospital. We followed up with the patients for at least 12 months, evaluated surgical outcomes, and investigated the factors associated with these outcomes by logistic regression analysis. Results: Surgical outcomes showed that 37 patients (88.1%) had excellent hip function, no abscesses, and no sinus tract formation. Four cases (9.5%) had sinus tract formations. One case (2.4%) had good hip function. Binary logistic regression models revealed that sinus tract formation was associated with preoperative tuberculosis infection syndrome. The average time to obtain antituberculosis drug treatment preoperatively was 4.6 weeks. Conclusion: Total hip replacement for active hip tuberculosis is a practical and promising treatment method. Surgeons should consider improving patients’ conditions before performing total hip replacement, administering antitubercular drugs, and arthrotomy to eliminate all abscesses, and decrease the risk of tuberculosis infection syndrome and the inflammatory response.
