Richard Smith ankle arthroplasty

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering

Background:

• Ankle joint replacement is an option for severe ankle arthritis.
• The 'ball-and-socket' prosthesis design aims to mimic natural ankle motion.

Purpose of the Study:

• To examine the indications for ankle joint replacement.
• To evaluate the outcomes of the Richard Smith 'ball-and-socket' ankle prosthesis.

Main Methods:

• Review of indications for ankle arthroplasty.
• Analysis of clinical outcomes for 24 Richard Smith ankle replacements.
• Follow-up data on 18 patients averaging 7 years post-surgery.

Main Results:

• Clinical outcomes of the Richard Smith prosthesis were analyzed.
• Long-term follow-up data was collected for a subset of patients.

Conclusions:

• The study discusses the findings in the context of current ankle replacement practices.
• The authors consider whether this specific prosthesis should be abandoned based on the results.
