  • Allowing asymmetric movement

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Patients suitable for Knee Replacement for:

  • osteoarthritis,
  • rheumatoid arthritis
  • bone necrosis affecting two knee compartments,
