Partial knee replacement provides pain relief for many with isolated OA.
Knee osteoarthritis (OA) is known for many things. For those with the condition, pain and swelling of the knee joint and the decreased mobility it causes are the most common symptoms. And because of its degenerative nature, knee OA is also often directly associated with a total knee arthroplasty. While more than 600,000 knee replacements are performed each year in the United States, a less extensive surgical option may be more beneficial for some with knee OA.
