Key result
In patients undergoing periacetabular osteotomy, those with mild hip dysplasia had a 10.5% rate of conversion to total hip arthroplasty, which was not significantly different from the 9.2% rate observed in patients with severe hip dysplasia (p=0.69).

Does periacetabular osteotomy improve pain and function in patients with mild hip dysplasia comparably to those with severe hip dysplasia?
Absolute Event Rate: 10.5% vs 9.2%
p-value: p=0.69
Periacetabular osteotomy in patients with mild hip dysplasia provides durable improvements in pain and function comparable to outcomes in severe hip dysplasia at midterm follow-up.
Potter et al. (2017) conducted a cohort in Symptomatic hip dysplasia (n=182). Mild hip dysplasia vs. Severe hip dysplasia was evaluated on Conversion to total hip arthroplasty (THA) (p=0.69). In patients undergoing periacetabular osteotomy, those with mild hip dysplasia had a 10.5% rate of conversion to total hip arthroplasty, which was not significantly different from the 9.2% rate observed in patients with severe hip dysplasia (p=0.69).
