How soon can you go swimming after reconstructive knee surgery?

Check with your doc: While the wound may heal well enough to submerge it in water in a week or two, there are many factors here. It is best to seek more advice from your orthopedic surgeon.

Ask your surgeon: Before beginning exercise you should check in with your surgeon. Certainly you will need to wait until the incision(s) have healed, but there may be other concerns depending on what specific procedure was performed. Only your surgeon or a therapist who works with your surgeon will be able to say when you are ok to swim or perform other exercises.

2 weeks: I usually tell my patients to wait 2 weeks. The skin is healed and stitches out before immersing the limb.
