[Total prosthesis implantation in the arthritic hip]

Area of Science:

• Orthopedic surgery
• Arthroplasty outcomes
• Hip joint reconstruction

Context:

• Hip arthrodesis, a procedure to fuse the hip joint, may require conversion to arthroplasty (hip replacement) in some cases.
• Evaluating long-term outcomes after converting hip arthrodesis to arthroplasty is crucial for patient management.
• Patient-reported outcomes can sometimes differ from objective clinical findings.

Purpose:

• To assess the long-term results of converting hip arthrodesis to arthroplasty.
• To determine if the duration of prior hip arthrodesis impacts the success of subsequent arthroplasty.
• To compare the outcomes of converted arthroplasties with general arthroplasty patient survival rates.

Summary:

• Eleven patients underwent conversion from hip arthrodesis to arthroplasty with follow-up ranging from 1 to 21 years.
• No significant difference in outcomes was observed between previously arthrodesed hips and ankylosed hips.
• The duration of the initial hip arthrodesis did not influence the long-term results of the conversion arthroplasty.

Impact:

• This study suggests that hip arthrodesis conversion to arthroplasty yields favorable long-term results, comparable to primary arthroplasty.
• The findings indicate that the history of hip fusion does not negatively affect the survival rate of hip replacement surgery.
• These results may inform surgical decision-making for patients with fused hips considering total hip replacement.
