Background
Uncemented total hip arthroplasty (THA) is increasingly preferred in younger patients due to its potential for long-term biological fixation and reduced cement-related complications. This study aimed to evaluate the functional and radiological outcomes of uncemented THA performed for various hip pathologies at a tertiary care center.
Materials and Methods
This prospective observational cohort study was conducted at Mahatma Gandhi Memorial Hospital, Warangal, and included 30 patients aged 20–60 years who underwent uncemented THA between September 2022 and August 2024. The mean age was 43.6 ± 9.2 years, with 56.6% males and 43.3% females. Clinical indications included chronic arthritis (53.3%), avascular necrosis (23.3%), femoral neck fractures with or without implant failure (19.9%), and developmental dysplasia of the hip (3.3%). Functional outcomes were assessed using the Modified Harris Hip Score (MHHS), and radiological outcomes focused on implant positioning and osteointegration.
Results
The mean MHHS improved significantly from a preoperative score of 46.2 ± 5.8 to a postoperative score of 85.6 ± 7.4 (p < 0.001), indicating substantial functional recovery. At final follow-up, 10% of patients had excellent functional outcomes (MHHS 90–100), 63.3% had good outcomes (80–89), 20% had fair outcomes (70–79), and 6.3% had poor outcomes (<70). Radiologically, 76.6% showed neutral femoral stem alignment, and 83.3% had optimally placed acetabular cups. Complication rates were low and manageable.
Conclusion
Uncemented THA provides significant functional improvement and satisfactory radiological outcomes with minimal complications. Proper patient selection, surgical technique, and structured rehabilitation are critical for optimal results.
Recommendations
Uncemented THA should include careful patient selection, accurate implant placement, and long-term follow-up to ensure functional success and stability.
