Aquatic Therapy Rehabilitation for Total Knee Replacement
Coping with knee pain or knee injuries can be both physically and emotionally exhausting. You may be thinking that ‘the pain will never go away’, or ‘rehab is going to hurt’ or ‘I will never run again’. Well, both those thoughts and the pain can be significantly diminished with warm water therapy.
Case Studies About Aquatic Therapy Rehabilitation for Total Knee Replacement
Clinical studies have proven the benefits of exercise in a warm water environment when recovering from knee surgery. A recent study by Drs. Mary Sanders and Daryl Lawson concluded that “an aquatic environment may be ideal during all phases of ACL rehabilitation post surgery.” Particularly following an intensive procedure, the added buoyancy of an aquatic environment relieves pressure on sensitive joints as they recover, allowing patients to slowly rebuild their strength through directed exercises.
During recovery from procedures typically performed on patients with osteoarthritis and other chronic conditions, such as a total knee replacement, the positive effects are even more pronounced.
Take the example of a Total Knee Replacement performed at the Kansas Joint and Spine Institute in Wichita, KS (from our video library). The patient received the surgery as a result of an injury that occurred 29 years prior! Fragments were beginning to break off of her knee cap and were ‘floating around’, which resulted in the need for this major surgery. The patient had the surgery on October 23rd and 4 days later, on the 27th she was in the pool.
“It was very pain free, I guess because gravity was not pulling my knee. And I loved it! But when you get out you can feel the workout. But I really was impressed!”- Knee Replacement Patient
The physical therapist, described in the case history that total knee rehab is a painful process because in order to move forward at all with the rehab process, you must work to move the joint. Therefore you are constantly causing trauma and inflammation to the knee, but using the pool for therapy helps ease that pain and reduce the swelling.
Speaking from much experience, the PT states that most patients who are discharged from the hospital from a knee surgery will be instructed to use aquatic therapy at the Kansas Joint and Spine Institute. She emphasizes the importance of starting off slow with controlled movements and then increasing the quantity and speed of the exercises as the joint warms up in the pool.
Benefits of Using Aquatic Therapy for Rehabilitation
The water is a great environment for patients rehabbing knee injuries, or any type of injury/surgery, because “any exercise you can do on land you can do in the pool with the added resistance or assistance of the water.”- PT at Kansas Joint and Spine Institute
Additionally, the water is a great place work on balance and strengthening the accessory muscles too. If the patient is using dumbbells, hydrotones or the balance rings at the same time someone else is in the pool, then they have to work twice as hard on their balance. Combining a strengthening exercise with an additional person in the pool creates waves and an ‘unstable environment.” Creating this unstable environment in the pool allows patients to strengthen additional muscles, making the transition to walking on land and uneven surfaces a lot easier.
For this particular rehab, there are many different exercises than can be performed. The patient begins in the aquatic therapy pool slowly warming up the joint with gentle squats, then hamstring stretches and lunges. Next she has the patient put fins around her ankle (as you can see in the video) and perform knee extensions. The faster you kick in the water, the more resistance you will feel. Lastly, the patient finishes on the treadmill walking at a slow pace to get the joint used to the ‘walking motion.’
Numerous other exercises can be performed for knee rehabilitation. Watch the full video case study on our video library and see how the water can help ease knee pain for total knee patients!
