PHASE 1: THE FIRST SIX WEEKS AFTER INJURY (grade 2 and 3)

                                 THREE WEEKS AFTER INJURY (grade 1)

                     

The knee should be to be protected with a hinged brace for 3 to 6 weeks, depending upon the severity of the injury.  Crutches and restricted weight bearing may be needed, as instructed by Dr. Gill.  Apply ice to control swelling.  Elevate the leg and use elastic stockings if the leg is swollen. As the pain lessens and the swelling decreases, try to gradually regain knee motion.  Avoid pivoting or twisting the knee because it might be unstable and give out.  Be careful getting out of cars, or catching your toe on a rug. When

walking, bear weight according to Dr. Gill’s instructions. Progress to no crutch(es) or brace when you can walk without a limp and there is no pain (per doctor instructions).  Ice the knee if there is pain and swelling.  Place a towel or cloth between the skin and the ice to prevent skin injury.  Ice for 20 minutes, three times a day.  At about two or three weeks following injury, the pain is usually subsiding and the swelling is lessened. You can now try to stretch the knee to regain motion. Stationary cycle, swimming (flutter kick only)

and the following exercise program are recommended.

 

STATIONARY  BICYCLE

 

Utilize a stationary bicycle to move the knee joint and increase knee flexion.  If you cannot pedal all the way around, then keep the foot of your operated leg on the pedal, and pedal back and forth until your knee will bend far enough to allow a full cycle. Most people are able to achieve a full cycle revolution backwards first, followed by forward.   You may ride the cycle with no resistance for 20 to 30 minutes a day.  Set the seat height so that when you are sitting on the bicycle seat, your knee is fully extended with the heel resting on the pedal in the fully bottom position. You should then ride the bicycle with your forefoot resting on the pedal.

 

QUADRICEPS SETTING

 

To maintain tone in the thigh (quadriceps) muscles and straighten the knee, lie on your back with the knee extended fully straight as in the figure.  Contract and hold the front thigh muscles (quadriceps) making knee flat and straight.  If done correctly, the kneecap will slide slightly upward toward the thigh muscles.  The tightening action of the quadriceps muscles should make your knee straighten and be pushed flat against the bed or floor.  Hold five seconds for each contraction.  Do at least 20 repetitions three or four times a day until you can fully straighten your knee equal to the uninjured side.  

 

HEEL PROP- to straighten (extend) the knee.

 

Lie on your back with a rolled up towel under your heel or sit in a chair with the heel on a stool as shown in the figure.  Let the knee relax into extension (straight).  If the knee will not straighten fully, you can place a weight (2 to 5 pounds) on the thigh, just above the kneecap.  Try to hold this position for 5 minutes, three times a day. While maintaining this extended position, practice quadriceps setting.

 

 

HEEL SLIDES - to regain the bend (flexion) of the knee.

 

While lying on your back, actively slide your heel backward to bend the knee.  Keep bending the knee until you feel a stretch in the front of the knee.  Hold this bent position for five seconds and then slowly relieve the stretch and straighten the knee.  While the knee is straight, you may repeat the quadriceps setting exercise.  Continue this exercise

until you can fully bend your knee equal to the uninjured side. Also, as you start to gain flexion, you can assist your efforts to gain flexion by assisting the heel slide with a towel. See illustration.  Repeat 20 times, three times a day.

                                             

You can advance to the following exercise program to help you regain knee motion and strength.  If the exercises can be performed easily after the first week, then an ankle weight may be used to increase the resistance of the exercise and to build strength.  Start with one pound and add one pound per week until you reach five pounds.

Do the exercises daily for the first week, then decrease to every other day when using ankle weights. You may ride the stationary bicycle daily for 10 to 20 minutes.

Avoid using stair-stepper machines, doing deep knee bends and squats or any exercise that causes crunching, clicking or pain at the kneecap.

 

 STANDING HAMSTRING CURL

                                                     

 Stand facing a table, using the table for balance and support. While standing on the unoperated  limb bend the knee of the operated side and raise the heel toward the buttock.  Hold this flexed position  for one second.  Slowly lower the foot back to the floor.   Keep the thighs aligned as illustrated. Repeat 20 times.

 

 

STANDING TOE RAISE

 

Stand facing a table, hands on the table for support and balance. Keep the knees extended fully.  Tighten the quadriceps to hold the knee fully straight.  Raise up on

‘tip-toes’ while maintaining the knees in full extension.  Hold for one second, then lower slowly to the starting position.  Repeat 20 times.

 

HIP ABDUCTION

Lie on your uninjured side. Keep the knees fully extended. Raise the operated limb upward to a 45-degree angle as illustrated.  Hold one second, and then lower slowly.  Repeat 20 times.

 

WALL SLIDES

 

Stand upright with your back and buttocks touching a wall.  Place the feet about 12 inches apart and about 6 inches from the wall.  Slowly lower your hips by bending the knees and slide down the wall until the knees are flexed about 45 degrees (illustration).  Pause five seconds and then slowly slide back up to the upright starting position.  Do 3 sets of 10 to 15 repetitions.      

 

STRAIGHT LEG LIFT

 

Tighten the quadriceps muscle so that the knee is flat, straight and fully extended.  Try to raise the entire operated limb up off of the floor or bed. If you are able to keep the knee straight raise the limb to about 45 degrees, pause one second and then lower slowly to the bed.  Relax and repeat. If the knee bends when you attempt to lift the limb off of the bed, do not do this exercise.  Keep trying to do the quadriceps setting exercise until you can lift the limb without letting the knee bend.  Repeat 20 times.

 

SHORT ARC LIFT

With the knee bent over a rolled up towel or blanket, lift the foot so that the knee fully straightens.  Hold the knee locked in extension for five seconds, then slowly lower.  Repeat 20 times.
