How long after a partial knee replacement can you walk without much pain and swelling?

Can be short: Recovery from a partial knee can be as quick as a few weeks. Partial knee recovery is much quicker than a total knee.

Within weeks: Most of my 500+ patients after their partial knee replacements have about 3-4 days of mild to moderate pain and swelling. They are instructed to walk around the house every hour that first week since they go home the same day. They use a walker or cane or crutches the first few days. Ice machines with knee wraps and stocking reduce the swelling and pain significantly. 2-3 weeks & 80-90% better.
