Background: Although medical management has improved the outcome and may have reduced the need for surgery, total hip arthroplasty (THA) is often required to manage pain and restore function and mobility. The successful functional outcome of THA in patients with inflammatory arthropathies is essential in understanding the need for THA, and its benefits in those undergoing it. Objective of the study is to evaluate the functional outcome of total hip arthroplasty in patients suffering from inflammatory arthritis using Harris hip score (HHS) and to assess the post operative complication in these patients.

Methods: In a prospective study conducted on patients with inflammatory arthritis treated with THA between a study period of January 2018 to January 2020. All the patients after assessing them clinically and radiologically were operated with uncemented THA through posterolateral approach. Functional outcomes of hip were evaluated using HHS at various intervals.

Results: In this study, patients were followed up to 24 months. About 46.7% of patients were diagnosed with rheumatoid arthritis, 33.3% of patients were diagnosed with ankylosing spondylitis, 20% of patients were diagnosed with sero negative arthritis. 90% of patients had no limb length discrepancy, no other post-operative complications were noted. The final functional outcome of hip according to HHS were 13.3% of excellent, 56.7% good results and 30% of fair results.

Conclusions: This study concludes that THA in patients with inflammatory arthritis with restricted activities of life had improved in short term follow up and ease of rehabilitation and return to function.
