After total knee replacement (TKR) surgery, you may require staying in the hospital for up to 3 days, according to the American Association of Hip and Knee Surgeons (AAHKS).

That said, how long you stay in the hospital will depend on your recovery. For example, you may have to reach certain milestones before leaving the hospital, including:

  • standing
  • controlling pain
  • getting around with the help of a walking device
  • being able to flex and extend your knee sufficiently
  • being able to get to and use the bathroom unaided

You may need to stay in the hospital longer if you’re not yet mobile or complications develop.


After surgery, you will most likely wake up from the anesthesia in the recovery room.

You may have a large, bulky dressing that will help control swelling.


A doctor may prescribe medications to help relieve pain, including:

Medications could be administered orally, intravenously, or by injection.

Exercises to help prevent blood clots after total knee replacement surgery

The American Academy of Orthopaedic Surgeons suggests that some exercises while lying in bed after TKR surgery may help maintain circulation and reduce the risk of blood clots. These may include:

  • Ankle pumps: Push your foot up and down several times every 5–10 minutes.
  • Ankle rotations: Move your ankle inward and outward five times, repeating this exercise three to four times daily.
  • Bed-supported knee bends: Lying down, slide your foot back toward your buttock, keeping your heel on the bed. Repeat 10 times, three or four times a day.
  • Straight leg raises: Tighten your thigh muscle and raise your leg a few inches, keeping it straight. Hold for 5–10 seconds, then gently lower.

Wearing compression socks may also help prevent clots, and a doctor will likely prescribe blood thinners to help, too.

Physical therapy is a common part of treatment to help restore balance, strength, and mobility. Your physical therapy regimen will usually begin within 24 hours after surgery.

A physical therapist will visit you several times to:

  • help you stand up as soon as possible
  • get you moving and help you adjust to your new knee
  • record your mobility, range of motion, and exercise progress

It’s important to get the most from these visits. The sooner you begin rehabilitation, the better your chances for a successful outcome and speedy recovery.

A doctor will develop a treatment plan to help you resume your day-to-day activities as soon as possible.

This may include a combination of natural remedies, medications, and physical therapy to help reduce pain and inflammation.

  • taking your medication for as long as the doctor prescribes, even if you feel better
  • attending all appointments with your doctor and physical therapist
  • practicing the exercises your physical therapist has prescribed

Early goals you can set yourself may include:

  • getting in and out of bed without help
