  Purpose

This evaluation is being conducted to evaluate the performance of the ASR arthroplasty. The performance of the devices will be assessed by:

Clinical parameters: pain, function, satisfaction and complications. Blood samples: Analyse of metal ions, lymphocyte migration, lymphocyte proliferation assay and cytokines.

Biopsies: Metal ions, cytokines and histology. Biomechanics: Strength, gait analysis, range of motion. Scanning: DEXA and MRI


Condition Intervention
Patients Suitable for THA Device: ASR hip prosthesis Device: ReCap hip prosthesis

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Clinical Performance of the ASR and ReCap Resurfacing Implants-7Years Follow-Up.
