Arthroscopic surgical procedures: See arm/group description of Arthroscopic surgery and sham surgery (HIPARTI). HARP: only arthroscopic surgery
Study summary
The primary aim of this study is to determine the efficacy of hip arthroscopic surgery compared to a sham surgery (diagnostic arthroscopy only) for patients with symptomatic and radiological findings related to impingement (FAI) and/or labral tears using a randomized controlled design (HIPARTI Study: Primary aim and the main paper: primary end point: iHOT 1 year follow-up)).
Our main hypothesis is that surgical procedures of the hip will demonstrate greater efficacy than sham surgery (diagnostic hip arthroscopy only) for hip related quality of life (iHOT-33) after 1 year and at further (HIPARTI Study).
The secondary aim of this study is to establish modifiable risk factors associated with pain, function, work participation and quality of life over 1 year in people aged 18-50 years with hip impingement and/or labral tears diagnosed at hip arthroscopy. (HARP Study: A separate paper will be published with this main aim for the HARP Study) Long-term follow-ups for HIPARTI Study as well as HARP Study will be performed at 2, 5 and 10 years (secondary aims and separate papers).
