Eligibility Criteria

Inclusion

  • Outside the United States:
  • The Oxford Partial Knee System is intended for use in individuals with osteoarthritis or avascular necrosis limited to the medial compartment of the knee and is intended to be implanted with bone cement (in the United States). Use of cementless femoral fixation is permitted outside of the United States only (if it complies with all local, state, and/or national and international regulations), however the same technique must be used consistently throughout the course of the study (cemented or cementless).

Exclusion

  • The exclusion criteria will include the same contraindications stated in the FDA approved labeling for the device (approved in PMA P010014). These contraindications include:
  • Infection, sepsis, and osteomyelitis
  • Use in the lateral compartment of the knee
  • Rheumatoid arthritis or other forms of inflammatory joint disease
  • Revision of a failed prosthesis, failed upper tibial osteotomy or post-traumatic arthritis after tibial plateau fracture
  • Insufficiency of the collateral, anterior, or posterior cruciate ligaments which would preclude stability of the device
  • Disease or damage to the lateral compartment of the knee
  • Uncooperative patient or patient with neurologic disorders who is incapable of following directions
  • Osteoporosis
  • Metabolic disorders which may impair bone formation
  • Osteomalacia
  • Distant foci of infections which may spread to the implant site
  • Rapid joint destruction, marked bone loss, or bone resorption apparent on roentgenogram
  • Vascular insufficiency, muscular atrophy, neuromuscular disease
  • Incomplete or deficient soft tissue surrounding the knee
  • Charcot's disease
  • A fixed varus deformity (not passively correctable) of greater than 15 degrees
  • A flexion deformity greater than 15 degrees
