Background
The objective of this study is to share our experience in total hip replacement for the treatment of ochronotic hip arthritis, in particular to report how to establish the diagnosis and some tips to limit complications.
Method
A cohort comprised of 10 patients (12 hips) with alkaptonuric hip arthritis. There were six men and four women with the mean age of 62.80 ± 7.57 years. All patients had a stiff spine, grossly restricted movements of hip joints, and severely limited daily routine activities. Total hip replacement was performed in all patients. The patients were evaluated at 6, 12, and 24 months after surgery, as well as every 4 years thereafter. Harris hip score was used to assess the functional outcome. The level of significance was set at p < 0.05.
Results
The mean follow-up lasted 16.70 ± 6.82 years (3 to 24 years). At the final available follow-up, nine patients returned to work, ambulate without an orthosis, and achieve complete pain relief. Harris hip score was improved from poor to excellent. One patient died 16 years after surgery due to breast cancer. No complication relating to prosthetic failures was detected.
Conclusion
Total hip replacement gives long-term satisfactory results in patients with alkaptonuric hip arthritis, resulting in comparable function of the hips in patients who undergo primary osteoarthrosis.
