Introduction:
The non-arthroplasty hip registry (NAHR) is a United Kingdom national register that monitors the efficacy of hip preservation surgery. We aim to highlight early experiences of incorporating the NAHR into our practice at a tertiary centre.
Methods:
Between December 2013 and February 2015, 381 patients were identified on the NAHR database that had undergone non-arthroplasty hip surgery. Patient-related outcome measures EuroQuol 5D-5L (EQ-5D) and the International Hip Outcome Tool 12 (iHOT-12) were recorded at baseline and 6 months.
Results:
The 289 arthroscopic surgeries showed a statistical significant difference (p<0.05) in iHOT-12 for both males (45.21-65.07) and females (34.57 to 55.53), and in EQ-5D for both males (0.59-0.75) and females (0.56-0.65). The 92 open procedures showed a statistical significant difference (p<0.05) in both iHOT-12 (31.71-62.42) and EQ-5D (0.54-0.68).
Conclusions:
Overall our results from the NAHR indicate hip preservation surgery is effective at relieving pain and improving quality of life in the short term.
