Knee arthritis
Knee arthritis is wear of the cartilage that cushions the joint. It is common in runners, tennis and pickleball players, and people with past knee injuries. The goal is to keep you active and comfortable for as long as possible.
What it often feels like
- Aching with walking, stairs or after sitting
- Stiffness and swelling after activity
- Grinding or a sense of the knee being worn
Where care usually starts
- Strengthening and low-impact conditioning
- Weight, footwear and activity strategies
- Anti-inflammatory approaches and, when appropriate, an injection
Orthobiologics: when they fit
For mild to moderate arthritis, PRP, BMAC or microfat using your own cells may be discussed after conservative care. They aim to reduce pain and improve function; they don’t regrow a new joint.
When surgery is considered
Partial or total knee replacement is considered when pain and lost function persist despite other care.
