Background: Hip dysplasia is a common condition in active adults with hip pain that can lead to joint degeneration. Periacetabular osteotomy (PAO) is a common surgical treatment for hip dysplasia. The effect of this surgery on pain, function and quality of life (QOL) has not been systematically analysed.Purpose: In adults with hip dysplasia: (1) evaluate differences in pain, function and QOL in those undergoing PAO and healthy controls; (2) evaluate pre- to post-PAO changes in pain, function and QOL; (3) evaluate differences in pain, function and QOL in those with mild versus severe dysplasia, undergoing PAO; and (4) evaluate differences in pain, function and QOL in those having primary PAO versus those with previous hip arthroscopy.Methods: A comprehensive, reproducible search strategy was performed on 5 different databases. We included studies that assessed pain, function and QOL in adults undergoing PAO for hip dysplasia, using hip-specific patient reported outcomes measures.Results: From 5017 titles and abstracts screened, 62 studies were included. Meta-analysis showed PAO patients had worse outcomes pre- and post-PAO compared to healthy participants. Specifically, pain (standardised mean difference [SMD] 95% confidence interval [CI]): −4.05; −4.78 to −3.32), function (−2.81; −3.89 to −1.74), and QOL (−4.10; −4.43 to −3.77) were significantly poorer preoperatively. Meta-analysis found patients experienced improvements following PAO. Pain improved from pre-surgery to 1-year (standardised paired difference [SPD] 1.35; 95% CI, 1.02–1.67) and 2 years postoperatively (1.35; 1.16–1.54). For function, the activities of daily living scores at 1 year (1.22; 1.09–1.35) and 2 years (1.06; 0.9–1.22) and QOL at 1 year (1.36; 1.22–1.5) and 2 years (1.3; 1.1–1.5) all improved. No difference was found between patients undergoing PAO with mild versus severe dysplasia.Conclusions: Before undergoing PAO surgery, adults with hip dysplasia have worse levels of pain, function and QOL compared to healthy participants. These levels improve following PAO, but do not reach the same level as their healthy participants.Registration: PROSPERO (CRD42020144748) |
