Treatment of Arthritis Associated With Legg–Calve–Perthes Disease With Modular Total Hip Arthroplasty

Abstract Legg–Calve–Perthes (LCP) disease can result in morphological deformities and associated adult hip arthritis. Thirty-five consecutive total hip arthroplasties (THA) were performed in 28 patients with a history of LCP using a non-cemented modular femoral component. There was one revision for...

Description
Summary:Abstract Legg–Calve–Perthes (LCP) disease can result in morphological deformities and associated adult hip arthritis. Thirty-five consecutive total hip arthroplasties (THA) were performed in 28 patients with a history of LCP using a non-cemented modular femoral component. There was one revision for late hematogenous infection and no evidence of prosthesis failure. Harris hip scores, on average, improved from 49.8 (26–73) to 93.9 (82–100) ( P < 0.05) after a minimum of 2 years follow-up (average, 8.2 years, range 2–14 years). Clinically, patients demonstrated diminished or no limping (94%, 33/35) and improved leg length equality post-operatively (100%, 35/35). This style of stem accommodated metaphyseal/diaphyseal size mismatch in 80% (28/35), allowed for abnormal anteversion in 71% (25/35), and resulted in radiographic improvements in trochanteric height ( P < 0.05), body weight lever arm ( P < 0.05), and leg length ( P < 0.05).
