A hip replacement can change your life in a single day, eliminating years of pain and unlocking the freedom to move again. But in the days and weeks that follow, there’s one part of recovery many patients don’t expect to be challenging: getting a good night’s sleep. Finding the right position, staying comfortable, and protecting your new joint while you rest is crucial for healing faster and moving better.
At NanoKnee™, we make recovery rapid, but we also know your results are even better when your body gets the quality rest it needs. In this blog, we’ll give you our best advice for sleeping comfortably after hip replacement surgery.
Why Sleep Matters After Hip Replacement
While you sleep:
- Your body shifts into repair mode, releasing growth hormones
- These hormones help rebuild tissue, repair muscle fibers, and stimulate bone regeneration
- Blood flow to your muscles and surgical site increases, delivering the oxygen and nutrients your hip needs to heal
Consistent, high-quality sleep after surgery can:
- Reduce pain and inflammation by lowering stress hormone levels like cortisol
- Accelerate tissue repair and bone healing through increased cell production during deep sleep
- Strengthen your immune system, lowering your risk of post-surgical infection
- Regulate mood and energy levels, helping you stay active and positive during recovery
Additionally, research shows poor or disrupted sleep can slow wound healing and delay mobility gains after joint replacement. The importance of deep, restorative sleep simply cannot be underestimated.
Best Sleep Positions After Hip Replacement
1. On Your Back (Supine)
- Keeps weight evenly distributed and minimizes stress on your new joint
- Use a pillow under your knees to maintain spinal alignment and relieve hip pressure
2. On Your Non-Operated Side
- Place a pillow between your knees to prevent your legs from crossing
- Supports proper hip alignment during the night
Positions to Avoid Early On
- Sleeping on your stomach (can strain the hip and lower back)
- Crossing your legs at the knees or ankles (increases dislocation risk in some approaches)
- Twisting your torso sharply while in bed
Pro Tips for Comfortable Post-Surgery Sleep
- Invest in a firm pillow between your knees—many patients prefer wedge pillows for added stability
- Use an elevated wedge or recliner for the first week if lying flat causes discomfort
- Maintain a cool, dark bedroom—optimal sleep environments promote deeper rest
- Stick to your pain management plan—taking medication or using ice before bed can reduce nighttime discomfort
- Practice gentle stretching before bed to prevent stiffness
- Keep your hips aligned and supported until your surgical team says otherwise
