Background

Hip arthroscopy outcomes for femoroacetabular impingement remain heterogeneous.

Purpose

To identify distinct recovery phenotypes after hip arthroscopy using unsupervised machine learning and determine preoperative predictors of phenotype membership.

Methods

We analysed 326 consecutive patients with complete 1-year HOS-ADL and HOS-Sports data.

n = 326 consecutive patients

Results

27% keep daily function but don't return to prior sports level

Complete Responders

41.7%

ADL-Dominant Responder

27.3%

Slow Progressors

19%

Non-Responders

12%

More results

ADL-Dominant phenotype was predicted by age >40 years (OR 3.42, p < 0.001), Tegner <5 (OR 2.87, p = 0.001), and Outerbridge III-IV (OR 2.41, p = 0.005).

Conclusion

4 robust recovery phenotypes exist, with 27% demonstrating ADL-sports dissociation predicted by older age, lower activity, and greater chondral damage. Recognition enables personalised preoperative counselling.
