Why don't you put a pillow under your knee after knee surgery?
After knee surgery, it is crucial to avoid placing a pillow directly under the operated knee because this position can significantly hinder the healing process. While it might seem like a comfortable or supportive position, it can lead to complications that delay recovery.
The Primary Reason: Preventing Knee Bending
The main reason to avoid putting a pillow under your knee after surgery is to prevent the knee from bending. Keeping the knee straight or in an extended position is often a critical part of post-surgical rehabilitation.
How Pillows Under the Knee Impact Healing
Placing a pillow under the knee causes it to remain in a bent or flexed position. This seemingly minor action can have several detrimental effects on your recovery:
- Difficulty in Healing: A bent knee can make it more challenging for the surgical site to heal properly. The tissues and structures that were repaired or replaced need to be in a specific alignment to mend effectively. Constant flexion can put undue stress on these areas.
- Upsetting the Surgical Site: Maintaining a bent position can irritate or "upset" the sensitive surgical area. This can lead to increased pain, swelling, or even affect the integrity of the surgical repair.
- Risk of Contracture: Prolonged bending can increase the risk of developing a knee flexion contracture, where the knee becomes stiff and unable to fully straighten. This condition can require additional therapy or interventions to correct, significantly prolonging your rehabilitation.
Optimal Positioning for Recovery
To facilitate proper healing and avoid complications, focus on positioning that encourages knee extension.
- Sleeping: When lying down, especially for extended periods like sleep, try to keep the operated leg as straight as possible. Some healthcare providers may even recommend placing a pillow under the ankle to allow the knee to gently extend.
- Resting: Avoid resting with the knee bent for long durations. If you need to elevate your leg, ensure the elevation supports the entire leg, keeping the knee straight.
- Following Medical Advice: Always adhere strictly to your surgeon's and physical therapist's specific instructions regarding positioning, exercises, and activity levels. They will provide tailored guidance based on your individual surgery and recovery needs.
Prioritizing proper knee alignment is a simple yet vital step in ensuring a successful and smooth recovery journey after knee surgery.
