Wear and tear on the knee is a painful truth many face. For such a small part of the body, it can have a major impact on your quality of life. Being mobile means moving your knee joint countless times a day and having to endure discomfort with every step is not a reality anyone should have to accept.

In many cases, ACL repairs and knee replacement operations are essential to restore mobility, but the recovery process can be slow and painful. But maybe, just maybe, it doesn’t have to be.

Recover Tips After a Knee Operation

  1. Focus on range of motion. It is more important to get your leg as straight as possible and to bend as far as possible. While the joint is healing, scar tissue is forming so this range of motion is important to avoid scar tissue build up. It is less important to focus on walking quickly and building strength, this should be viewed as a second phase of your recovery.
  2. Keep your pain management under control. Use Cold Therapy and medication as prescribed by your doctor.
  3. During rehabilitation and exercise, don’t try to progress too quickly. Further to point one; motion before mobility. Take it slow to avoid possible hurting your joint or slowing your recovery.
  4. Do not compare your progress to other people’s progress. If you do both knees at the same time, expect them to recover at different rates. Each joint should be allowed to recover at its own pace.
  5. Don’t stop therapy too soon or avoid it completely. Therapist know how to stretch your joints to acceptable limits without causing damage, but drastically improving range of motion.

Ice Therapy Benefits & Tips

  1. Pads should never come in direct contact with the skin, always use a protective wrap, a liner or a towel to ensure you do not over-cool and damage your skin. A towel can be used between the pad and your skin to ensure there is no direct contact between the two.
  2. Do not over cool an area. Use for 30 minute sessions and check your skin in-between sessions. Excessive cold can cause frostbite.
  3. These therapy units are much more convenient and less messy to use than conventional ice packs. Keep your freezer stocked with ice and all you need to do is drop it in the cooler when you need to use your machine. You can also freeze small bottles of water and simply drop them in the cooler. Refreeze them once they have melted.
  4. Cold therapy decreases the need for anti inflammatory medications by reducing pain symptoms and surgery swelling.
  5. Consult your doctor to ensure you use the system according to your specific needs.
  6. A post knee surgery ice machine is commonly used for both knee replacements and ACL repairs (Anterior Cruciate Ligament).
