Effective Rehabilitation Strategies for Post-Knee Replacement Patients

Rehabilitation issues

I am 35 years old and a patient with rheumatoid arthritis.
I have the following questions: I had total knee replacements on my left and right knees in July and October of this year, and my recovery has been good.
However, I still have a bit of a wobble when walking and am not very agile.

1.
My doctor advised me to do leg raises, which I can practice while sitting or lying down.
How much will practicing leg raises help with climbing stairs? What other exercises should I do to be more effective?
2.
I still need to use my hands for support when climbing stairs (I have only climbed stairs three times since the surgery because I am a bit afraid to do so).
I plan to start practicing stair climbing after three months; I wonder how effective that will be.
Am I going to need hand support to climb stairs in the future?
3.
Before the surgery, my knee joint was severely damaged, so will that affect my rehabilitation? Is climbing stairs a form of rehabilitation, or should I avoid climbing stairs?

Dr. Shi Guozheng reply Orthopedics

Leg raises strengthen the quadriceps muscles in the thighs, and doing them more frequently can enhance walking and climbing stairs.
Once the strength in the legs is sufficient, climbing stairs becomes easier, so there is no need to rush into stair climbing practice.
In rheumatoid arthritis, not only are the bones damaged, but the soft tissues are also affected.
If the knee joint is severely deformed or worn before surgery, the outcomes post-surgery may be slightly less favorable.
However, if the surgery is performed well, the function of the knee joint will gradually improve.
Individuals who have undergone total knee arthroplasty should avoid frequent stair climbing, as these activities are more strenuous and can accelerate joint wear.

More Info

After undergoing total knee replacement surgery, especially for patients with rheumatoid arthritis, effective rehabilitation is crucial for regaining mobility and strength. Your concerns about your recovery process are valid, and I will address each of your questions while providing additional insights into effective rehabilitation strategies.

1. Leg Raises and Stair Climbing: Leg raises are an excellent exercise for strengthening the quadriceps, which play a vital role in stabilizing the knee joint and facilitating movements such as stair climbing. By practicing leg raises while sitting or lying down, you can enhance your muscle strength without putting undue stress on your knee. This exercise helps improve your range of motion and prepares your muscles for more demanding activities like climbing stairs.
In addition to leg raises, consider incorporating other exercises such as straight leg raises, heel slides, and ankle pumps. These exercises can help improve flexibility and strength in the knee and surrounding muscles. Resistance training with light weights or resistance bands can also be beneficial as you progress. Always consult your physical therapist for personalized recommendations based on your recovery stage.

2. Stair Climbing Confidence: It’s understandable to feel apprehensive about climbing stairs post-surgery. Using handrails is a good practice for safety and stability. As you approach the three-month mark, you should gradually start practicing stair climbing under the guidance of your physical therapist. They can provide you with techniques to improve your confidence and reduce reliance on handrails over time.
Stair climbing is indeed a form of rehabilitation as it mimics daily activities and helps improve functional strength. Start with a few steps at a time, focusing on proper technique—step up with your stronger leg first, then follow with the weaker leg. As you gain strength and confidence, you can gradually increase the number of steps you climb.

3. Impact of Pre-existing Knee Damage: The condition of your knee prior to surgery can influence your rehabilitation process. If your knee was severely damaged before the surgery, it may take longer to regain full function. However, this does not mean that you cannot achieve significant improvement. Consistent rehabilitation exercises tailored to your specific needs will be essential.
Climbing stairs can be a beneficial part of your rehabilitation, but it should be approached with caution. It’s important to listen to your body and not push through pain. If you experience discomfort, it may be wise to reduce the frequency of stair climbing until you build more strength and confidence.
In summary, effective rehabilitation after knee replacement surgery involves a combination of strength training, flexibility exercises, and functional activities like stair climbing. Regular communication with your healthcare team, including your physical therapist, will ensure that your rehabilitation plan is safe and effective. They can help you set realistic goals and monitor your progress, making adjustments as needed to optimize your recovery.
Remember, recovery is a gradual process, and it’s important to be patient with yourself. With dedication to your rehabilitation exercises and proper guidance, you can achieve improved mobility and a return to your daily activities.
