Description of intervention(s) / exposure
This retrospective study aims to evaluate long term outcome of patients who underwent hip arthroscopy prior to peri-acetabular osteotomy (PAO) surgery.

The study involves reviewing patient files and operating notes with a subsequent phone call or a follow up visit (as per normal scheduled patient follow-up post surgery), if possible, to evaluate current patient status.

Participants for this study are located/recruited from clinic patient files from the date range 2001 to 2008.

Outcomes
Primary outcome [1] 288431 0
We aim to evaluate the importance of arthroscopy prior to the osteotomy procedure. This is to supply the surgeon with additional valuable pre-operative data which will establish a better treatment strategy.
the validated scoring clinical tools of the WOMAC hip score, Mahorn Hip Outcome Tool (MHOT) and the Non-arthritic hip score will provide functional quantitative data. Total assessment of clinical signs and symptoms will also be analysed. This will allow for a greater proportion of qualitative analysis, combined with the quantitative data collected via the validated questionnaires.

Trial 134 -Long term outcome of peri-acetabular osteotomy and the efficacy of Arthroscopic surgery prior to the index procedure

Summary
Brief summary
We aim to evaluate the importance of arthroscopy prior to the osteotomy procedure. This is to supply the surgeon with additional valuable pre-operative data which will establish a better treatment strategy. We will then evaluate patient outcomes following these two procedures.

This kind of osteotomy surgery aims to address an uncommon entity - mild hip dysplasia. Evaluation of this unique operation and its outcomes in this type of patient population will be invaluable in further improving patient care.


Key research questions:
1. Does PAO carry good long-term outcomes.
2. Is hip arthroscopy considered as a adjunctive procedure prior to PAO
