How to Relieve Back Pain After Knee Surgery

Pain in your knee after surgery is expected. A nagging ache in your lower back, however, can be a frustrating surprise. If this sounds familiar, you're not alone. Post-op back pain is common and happens because your body is a connected system.

You can feel better by making small changes to how you sit and sleep. Also, gentle movements can help your healing joint. If you’re looking for how to relieve back pain after knee surgery or dealing with back pain after knee replacement, the strategies below can help.

Summary

Post-op back pain after knee surgery (including lower back pain after knee replacement and backache after knee replacement) is common, typically caused by gait imbalance and upper-body strain from assistive devices.

You can find relief by keeping your spine straight while you sleep. Use pillows to help with this. Try gentle movements that don't hurt, like pelvic tilts or bringing one knee to your chest. Sit in a chair that supports your lower back.

Be careful when you sit down or stand up. When using crutches or a walker, stand up straight.

Seek medical advice for sharp, radiating pain, new numbness/tingling or weakness, or bowel/bladder changes. A simple daily checklist helps reinforce these habits for a smoother recovery.

Why Your Back Aches After Knee Surgery

To shield your healing knee, your entire walking pattern changes. This new, uneven walk—sometimes called a gait imbalance—is the primary culprit. Your body puts more weight on your "good" leg, causing your hips to become lopsided.

To keep you from tipping over, your back muscles must work overtime to hold you upright. These postural changes and muscle compensation are what you feel as a deep, persistent ache.

Adding to this, the very tools that help you walk can also contribute to the strain. Leaning forward on a walker or hunching over crutches pulls on your shoulder, neck, and back muscles in unfamiliar ways. This combination of an altered walk and new upper-body stress is the main reason your back hurts after surgery. These changes can also explain hip pain following knee surgery or back pain after TKR (total knee replacement), including bouts of lower back pain after TKR in the early recovery period.

How to Find the Best Sleeping Position to Avoid Backache

Finding a comfortable spot in bed can feel impossible when both your back and knee are aching. The goal is to keep your spine in a neutral, relaxed line, giving those overworked back muscles a much-needed break. A few strategically placed pillows can make a world of difference in preventing morning stiffness. If your hip hurts after knee surgery, these positions can also help keep your hips aligned and reduce strain.

• On your back: This is often the ideal position. Place a pillow under your knees to create a slight bend, which immediately releases tension in your lower back. These adjustments can ease lower back and hip pain after TKR.

• On your side: If you're a side-sleeper, tuck a firm pillow between your knees. This keeps your top leg from pulling your hips out of alignment and twisting your spine.

Try not to sleep on your stomach. This position can make your lower back curve too much and twist your neck. Getting your alignment right during sleep is a passive way to find significant relief.

3 Safe and Gentle Stretches for Immediate Back Relief

Beyond passive relief, a few simple movements can actively ease your aching back. The main rule is to stretch without pain. If a stretch hurts your back or knee sharply, stop right away.

The goal is gentle release, not a strenuous workout. These back stretches are designed to be performed during knee recovery without putting stress on your healing joint.

A great place to start is with a seated pelvic tilt. Sit on the edge of a strong chair. Move your hips gently to press your lower back against the chair. Then, lean forward to make a small curve in your back.This subtle movement helps reawaken the deep core muscles that provide crucial post-op support for your spine.

Another excellent stretch is the single knee-to-chest, using your non-surgical leg. Sit tall and gently draw your goodknee toward your chest until you feel a light stretch in your lower back and hip. Hold for 15-20 seconds. This classic physical therapy exercise directly eases back tension without involving the recovering leg and can also help when hip pain following knee replacement shows up alongside lower back tightness.

How to Walk and Sit Without Making Back Pain Worse

Apply the awareness from stretching to your everyday movements, starting with how you sit. Avoid slumping into soft couches. Instead, choose a firm chair and sit with your back straight.

To give your spine extra help, place a small, rolled-up towel in the curve of your lower back. This simple trick provides lumbar support, helping your back muscles relax.

When getting up, practice mindful movement. Scoot to the edge of the chair and plant your good foot firmly on the floor. Use the chair's armrests to push yourself up, engaging your arms and non-surgical leg while keeping your back as straight as possible. This technique shifts the workload away from your vulnerable back.

Finally, pay attention to your posture while using crutches or a walker. It's natural to hunch over, but this puts immense strain on your entire spine. Try to stand tall, relax your shoulders, and look ahead to reduce back strain. These cues also help reduce back pain after knee replacement and back pain after TKR by improving alignment while you heal.

Is Sciatic Pain Normal? When to Call Your Doctor

While a dull, muscular ache is common, a sharp, traveling pain is different. A tired muscle feels sore, but a pinched nerve feels more like a zapping electrical signal. This radiating discomfort, sometimes called sciatica, is a sign that a nerve might be irritated.

It's time to call your doctor or physical therapist if you experience:

• Sharp, shooting, or electric-shock-like pain down your leg.

• New numbness, tingling, or significant weakness in your foot or leg.

• Any loss of bladder or bowel control.

These symptoms are rare but require professional evaluation. Contact your surgeon promptly if you develop severe back pain after knee replacement along with these red-flag symptoms. The vast majority of back pain after knee surgeryis muscular strain that will improve as you get stronger and your walk returns to normal.
