Avoiding setbacks and protecting your new joint during recovery
Knee replacement surgery can be life-changing: but only if recovery is handled with care. While it is natural to want to get back to normal life quickly, certain movements and habits can jeopardise healing, increase pain, or even damage your new joint.
At Orthopaedic Innovation, we guide patients through every stage of recovery. Our procedures are designed to eliminate pain and restore mobility using advanced implants and minimally invasive techniques. Below, we outline the most important things not to do after knee replacement surgery; so you can heal safely and confidently.
1. Don’t Sit for Long Periods Without Moving
Prolonged sitting increases swelling and raises the risk of blood clots. In the first few weeks, aim to stand or walk for a few minutes every hour. If seated for longer, elevate your leg to reduce fluid build-up.
The NHS recovery guide1 recommends walking for five minutes every hour to prevent complications like deep vein thrombosis.
2. Don’t Cross Your Legs
Crossing your legs at the knees or ankles can strain the joint and restrict circulation. Keep your legs uncrossed and supported when sitting or lying down - especially during the first six weeks.
3. Don’t Place a Pillow Under Your Knee
Sleeping with a pillow directly under your knee may feel comfortable but can lead to stiffness and reduced range of motion. Instead, place a pillow under your ankle to gently encourage full extension.
4. Don’t Kneel or Twist
Kneeling puts direct pressure on the joint, and twisting can strain surrounding ligaments. Avoid both until your surgeon or physiotherapist confirms it’s safe.
5. Don’t Lift Heavy Objects
Lifting heavy items (like grocery bags, laundry baskets, or gym weights) can stress your healing knee. Wait at least three months before resuming strenuous tasks, and always lift with proper technique.
6. Don’t Return to High-Impact Sports
Running, jumping, and contact sports place excessive force on your new joint. These activities can shorten implant lifespan or cause damage. Stick to low-impact options like swimming, cycling, or walking.
OrthoBethesda2 advises avoiding high-impact sports and uneven terrain during early recovery.
7. Don’t Ignore Pain or Swelling
Some discomfort is normal; but sharp pain, excessive swelling, or warmth around the joint could signal a complication. Always report unusual symptoms to your care team promptly.
8. Don’t Drive Too Soon
Driving requires strength, reflexes, and control. Most patients can drive again after 6 weeks — once cleared by their surgeon. Never drive while taking opioid pain medication.
9. Don’t Skip Your Exercises
Recovery depends on movement. Skipping physiotherapy or home exercises can lead to stiffness, weakness, and delayed healing. Follow your programme consistently: even when progress feels slow.
