Post-Surgery Knee Rehabilitation: Tips for Straightening and Recovery - Orthopedics

Inability to fully extend the knee while bent?


Hello, doctor.
I had knee surgery at the end of September and have been recovering for two months.
My knee is still in the process of bending, and I need to perform leg extension exercises.
I would like to know how long I should hold the leg extension, how long I should rest, and how many times a day I should do this? (For reference, I had a right knee medial meniscus repair with cartilage grafting and an outer cartilage transplant surgery at the end of September, and I am currently in the rehabilitation phase.)
I have another question regarding the outer side of my right thigh.
When I press on the quadriceps area with my fingers, I have asked my surgeon, and he mentioned that my bone is healing.
However, I often feel warmth on the sides, especially at night while sleeping.
Is this normal?

1.
The duck leg exercise should be done for about 5 seconds and can be performed multiple times a day.
It is recommended to do it for about ten minutes every hour, followed by a rest.
2.
It is normal for the surgical site to feel warm during rehabilitation.

Post-surgery knee rehabilitation is a critical phase in the recovery process, especially after procedures like meniscus repair or cartilage grafting. Given your situation, where you had surgery on your right knee at the end of September, it’s essential to follow a structured rehabilitation program to ensure optimal recovery and regain full function of your knee.


Tips for Straightening the Knee
1. Gentle Stretching: To help straighten your knee, you can perform gentle stretching exercises. A common method is to sit on the floor with your legs extended in front of you. Gradually try to push your knee down towards the floor, holding the stretch for about 15-30 seconds. Rest for the same amount of time between stretches. Aim to do this 3-4 times a day.

2. Heel Slides: While lying on your back, slide your heel towards your buttocks, bending your knee as much as possible, and then slide it back down. This exercise helps improve the range of motion. Perform this exercise 10-15 times per session, 2-3 times a day.

3. Quadriceps Sets: While sitting or lying down, tighten your thigh muscle (quadriceps) and hold for 5-10 seconds, then relax. Repeat this 10-15 times, 3-4 times a day. This exercise is crucial for building strength in the quadriceps, which supports the knee.

4. Knee Extension: You can use a rolled towel or a small pillow under your ankle while sitting. Let your knee hang off the edge of a chair or bed to encourage straightening. Hold this position for 15-30 seconds, repeating several times throughout the day.


Frequency and Duration
- Daily Routine: Aim to perform your stretching and strengthening exercises at least 2-3 times a day. Consistency is key to recovery.

- Duration: Each session should last about 15-30 minutes, depending on your comfort level and the exercises you are performing.


Monitoring Symptoms
Regarding the warmth you feel in your thigh area at night, this can be a normal part of the healing process. After surgery, it’s common for the body to experience increased blood flow to the area as it heals, which can cause a sensation of warmth. However, if you notice any swelling, increased pain, or redness, it’s essential to consult your physician to rule out any complications such as infection or deep vein thrombosis (DVT).


Additional Considerations
- Physical Therapy: If you haven’t already, consider working with a physical therapist. They can provide personalized guidance and ensure you’re performing exercises correctly, which is crucial for recovery.

- Pain Management: If you experience pain during exercises, it’s important to listen to your body. You may need to modify the intensity or duration of your exercises. Over time, as your knee becomes stronger and more flexible, you should be able to increase the intensity of your rehabilitation exercises.

- Follow-Up Appointments: Keep regular follow-up appointments with your orthopedic surgeon or healthcare provider. They can assess your progress and make necessary adjustments to your rehabilitation plan.


Conclusion
Rehabilitation after knee surgery is a gradual process that requires patience and commitment. By incorporating these exercises into your daily routine and monitoring your symptoms, you can work towards regaining full function of your knee. Always consult your healthcare provider before starting any new exercise regimen, especially post-surgery, to ensure it aligns with your recovery plan.
