If you’re suffering from advanced osteoarthritis and nonsurgical treatments aren’t helping to relieve the symptoms, you might be a good candidate for partial knee replacement, according to the American Association of Hip and Knee SurgeonsOff Site Icon (AAHKS).
A partial knee replacement, according to the National Institutes of HealthOff Site Icon (NIH), would be a good option for you if you:
Are not very active
Have good range of motion in your knee
Have only a minor knee deformity
Have stable ligaments in your knee
Only have bad arthritis in one part of your knee
A partial knee replacement is offered to patients who meet certain criteria. In order to be considered a good candidate for a partial knee replacement:
you need to have osteoarthritis in only one part of the knee
you can not be too heavy
you can not have a significant deformity
you do not have an ACL tear
and your range of motion needs to be nearly normal.
Partial knee replacement is appropriate for patients with arthritis that is confined to a single compartment of the knee and is generally restricted to patients who are not morbidly obese. The surgery is not appropriate for patients with marked stiffness in the knee or those with a significant angular deformity. Intact ligaments are generally a requirement for a partial knee replacement. Patients with rheumatoid arthritis are not candidates for partial knee solutions since inflammatory-type arthritis typically involves the entire joint.
