Treatment at Mayo Clinic

By Mayo Clinic Staff

If the cartilage in just one of the knee's sections becomes damaged, Mayo Clinic surgeons can sometimes replace just the damaged section instead of the whole knee joint. Recovery is easier than with total knee replacement, but the results may not last as long, because arthritis could develop in other areas of the knee.

Minimally invasive surgery

Minimally invasive techniques allow surgeons to replace a knee using smaller incisions. This usually results in less pain and a quicker recovery. But minimally invasive knee replacement requires special surgical training, and it may not work for everyone. Your orthopedic surgeon will determine whether you're a good candidate for the minimally invasive approach.

Robotic assistance

Some Mayo Clinic surgeons use a computer-guided robotic arm during knee replacement surgeries. This device helps the surgeon remove as little bone as possible and precisely align the artificial joint to the bone.
