[First experiences with total hip resurfacing arthroplasty]

Area of Science:

• Orthopedic Surgery
• Biomaterials Engineering

Background:

• Hip arthritis affects young and active individuals, necessitating effective treatment options.
• Surface arthroplasty offers a potentially joint-preserving alternative to traditional hip replacement.

Purpose of the Study:

• To evaluate the early clinical outcomes of surface arthroplasty in a cohort of young and active patients.
• To assess the efficacy and safety of ReCap and BHR endoprostheses in this patient group.

Main Methods:

• A prospective study involving 25 surface arthroplasties (24 ReCap, 1 BHR) in patients aged 23-64 years.
• Idiopathic arthritis was the primary indication in 20 patients.
• Follow-up ranged from 10 to 20 months, with clinical assessment using the Harris Hip Score.

Main Results:

• Excellent clinical results were observed, with an average Harris Hip Score of 95.8 (range 90-100).
• Average acetabular cup inclination was 51.2 degrees and average femoral head angle was 140.3 degrees.
• No significant intraoperative or early postoperative complications were reported.

Conclusions:

• Surface arthroplasty is a valuable treatment option for young, active patients with hip arthritis.
• The procedure is technically demanding, requiring specialized surgical skills.
• Early results suggest favorable outcomes and support the use of surface arthroplasty in select patient populations.
