After an injury or surgery, an exercise conditioning program will help you return to daily activities and enjoy a more active, healthy lifestyle. To ensure that the program is safe and effective for you, it should be performed under your doctor's supervision. Talk to your doctor or physical therapist about which exercises will best help you meet your rehabilitation goals.

  • Strength : Strengthening the muscles that support your knee will reduce stress on your knee joint. Strong muscles help your knee joint absorb shock.
  • Flexibility : Stretching the muscles that you strengthen is important for restoring range of motion and preventing injury. Gently stretching after strengthening exercises can help reduce muscle soreness and keep your muscles long and flexible.
  • Target Muscles : The muscle groups targeted are - Quadriceps (front of the thigh), Hamstrings (back of the thigh), Abductors (outer thigh), Abductors (inner thigh), Gluteus medius and gluteus maximus (buttocks)
  • Warm up : Before doing the exercises, warm up with 5 to 10 minutes of low impact activity, like walking or riding a stationary bicycle.
  • Stretch : After the warm-up, do the stretching exercises before moving on to the strengthening exercises.
  • Do not ignore pain : You should not feel pain during an exercise. Talk to your doctor or physical therapist if you have any pain while exercising.

There are many exercises which will help you meet your rehabilitation goals.

The small puncture wounds take several days to heal. The operative dressing can usually be removed the morning after surgery and adhesive strips can be applied to cover the small healing incisions.

Although the puncture wounds are small and pain in the joint that underwent arthroscopy is minimal, it takes several weeks for the joint to maximally recover. A specific activity and rehabilitation program may be suggested to speed your recover and protect future joint function.
