CPM Goals Extensions Flexion
Day 1 10 70
Day 2 0 70
Day 3 0 80
Day 4 0 90
Day 5 0 100
Day 6 0 110
Day 7 0 115
These are general goals. If it is too painful to reach any of these goals, simply set the machine at a more comfortable setting and reach these goals at a slower pace. Once you have reached 115 degrees of flexion, continue using the CPM until your doctor has advised you to stop.
Cold Therapy Machine
If you are using a cold therapy machine, fill the unit with ice and water when you return home after surgery. Plug the unit into a convenient wall socket and set the temperature somewhere between 40 and 50 degrees. You should use the cold therapy machine continuously, as long as you are having pain and/or swelling (usually two to three weeks). You will need to have the ice changed every four to six hours to keep the temperature in range. Always have fabric (e.g. dressings, pillow case) between the cold therapy pad and your skin. The cold pad can cause frostbite without this.
If you are using an interferential stimulator, plug the unit into a convenient wall socket when you return home from surgery and turn it on to the Pain Control setting. See the protocol for appropriate settings. You will use the interferential stimulator for as long as you are having pain and/or swelling (usually two to three weeks).
The interferential stimulator is designed to help control pain and swelling. Hopefully this will help to decrease the amount of pain medication you will need following surgery. If, however, the inteferential stimulator does not relieve all your pain, you may still take your pain medication per the instructions you received from your physician. Do not use the interferential stimulator at night. It can overheat if caught under you or blankets.
The post-op brace is designed to protect your knee in case you slip or fall. It is very important to wear this brace at all times including while you sleep. However, you must remove the brace when you are in the CPM machine. The hinge on the brace is set to 10 degrees extension and 70 degrees fexion. This will allow you protected range of motion to bend your leg. You will need to wear this brace for four to six weeks.
When you are finished with the CPM machine you will be fitted for a functional brace. This brace is designed to protect your reconstructed ACL when you return to work and activities. Your reconstructed ACL will go through a period when it is weak and vulnerable to stretching. This period can last for several months. Because of this, your doctor has prescribed this brace.
The Donjoy brace is specifically designed to protect the ACL from stretching during this vulnerable period. Its patented Four-Points-of-Protection technology was designed to place opposing forces on your tibia and femur to prevent the tendency of your tibia to slide forward in relation to your femur. This is the motion that your ACL controls in the knee. It is this motion that can potentially damage your reconstructed ACL if it occurs when the ACL is in a weakened state. This brace will typically be used stating two to three months after surgery and continuing for a full year after surgery. Your doctor will advise you for what activities you will need to wear this brace.
Do not use this brace until your doctor has cleared you for activities, usually two to three months after surgery.
