Disease or Condition   Osteoarthritis / Hip Replacement
Title   ReCap Total Resurfacing System (Osteoarthritis / Hip Replacement)
Description   This study is for patients with degenerative joint disease of the hip. The purpose of this research study is to look at the safety and effectiveness of the ReCapĂ’ Total Resurfacing System in reducing pain, discomfort and/or loss of function patients are currently having in their hip. The ReCap Total Resurfacing system is not FDA approved except for research. The ReCapĂ’ Total Resurfacing System consists of two (2) implant devices: 1. The femoral head is the ball attached to the thighbone in your leg. The metal resurfacing device is designed to replace the outer surface of your femoral head with a metal "cap" while saving as much natural bone as possible; 2. The acetabulum is the socket in your hip bone into which the femoral head fits. A metal liner will replace your natural acetabulum (socket). This liner is similar to the "socket" devices used in common total hip replacements.

  • Patients with a pre-operative Total Harris Hip Score of > 70

  • Previous prosthetic hip replacement device (including other surface arthroplasty, endoprosthesis, etc) in the operative hip

  • Contralateral hip prosthesis (total hip replacement or surface replacement), including staged or simultaneous procedures

  • Developmental dysplasia, which prevents stable acetabular reconstruction

  • Patients with previous Girdlestone procedures

  • Patients with a clinical condition that may limit follow-up, including: immuno-compromised conditions, hepatitis, active tuberculosis, active neoplastic disease such as carcinoma of the prostate, lung, stomach, cervix, etc., chronic renal failure, organ transplant recipients, known terminal disease process

  • Patients with a "fused" hip

  • Patients with metal allergy or hypersensitivity

  • Participation in a study of any investigational product (drug or device) within the past 12 months
