Abstract: Background: Increased use of Hip Arthroplasty has resulted in a high incidence of Failed Hip Arthroplasty with progressive groin pain and prosthetic failures which need revision arthroplasty. This study evaluates the surgical and functional outcome, along with the associated complication rates in patients undergoing Revision Hip Arthroplasty.
Material and Method: We studied 20 patients who underwent revision Total Hip Arthroplasty for Failed Hip Arthroplasty. All patients were operated under hypotensive spinal-epidural anesthesia in lateral position. Patients were evaluated at pre-op and post-op follow-up periods with serial radiography, Harris Hip Score (HHS) for pain and disability scoring, Oxford Hip Score (OHS) for pain, and functional scoring.
Result: The post-operative VAS score has decreased to 2.5 ± 1.01, from a pre-operative score of 8.02 ± 1.28, p< 0.001. The average Harris Hip Score has improved from 44.85 ± 9.32 pre-operatively to 84.60 ± 10.98 post-operatively at 6 months, p< 0.001 and average modified Oxford Hip Score has improved from 11.45 ± 1.77 pre-operatively to 38.85 ± 3.82 post-operatively at 6 months, p< 0.001. At 6 month follow-up, we had 50% excellent results, 30% good results, 15% fair results, and 5% poor results based on Harris Hip Score.
Conclusion: Conversion of symptomatic Failed Hip Arthroplasty to Revision Total hip replacement has good functional outcomes and significant pain relief leading to improved quality of life with marginally increased risk of intra-operative complications.
