What is the recovery time for knee surgery?

Most people who have total knee replacement surgery are walking comfortably at six weeks, but they may still require minimal assistance, notes WebMD. ACL surgery recovery is much faster, as most people feel comfortable enough to drive at the two-week mark, according to Emory Healthcare.

Physical therapy is required for knee reconstruction surgery and ACL surgery, states WebMD and Emory Healthcare. Physical therapy in a rehabilitation center for people with knee reconstruction normally lasts up to 10 days, while physical therapy at home usually lasts one to two months. Physical therapy for ACL surgery patients can last up to four weeks.
