What exercises should you avoid after hip or knee replacement?

  • Posted by: Bas van Beest

After hip or knee replacement surgery, certain exercises can put unnecessary stress on your new joint and slow down your recovery. High-impact activities, deep squatting movements, excessive twisting, and exercises that force your joint beyond recommended ranges all pose risks during the healing process. Understanding which movements to avoid helps protect your investment in surgery whilst building strength safely for long-term joint health.

What movements put your new hip or knee at risk?

Your new hip or knee is vulnerable to specific movements that can compromise the prosthesis or damage healing tissue:

  • Deep flexion beyond 90 degrees – Bending your joint past this angle can dislocate a hip replacement or damage the soft tissue envelope around a knee replacement before the surrounding structures have fully stabilized
  • Excessive rotation and twisting – These movements create shearing forces that healing tissue cannot handle effectively, potentially loosening the prosthesis or tearing vulnerable soft tissue
  • High-impact forces – Activities that generate forces several times your body weight through the joint can loosen the prosthesis or cause inflammation before the surrounding bone and tissue have adapted gradually
  • Extreme range of motion movements – Pushing into end ranges before your body has developed adequate scar tissue and muscle stabilization around the prosthesis risks both dislocation and tissue damage

During the initial recovery phase, your body needs time to develop scar tissue around the prosthesis and strengthen the muscles that stabilize your new joint. While your artificial joint will eventually handle demanding loads, the surrounding structures require gradual adaptation to prevent complications that could set back your progress. The good news is that these restrictions aren’t permanent—as your body adapts to the artificial joint over several months, you’ll gradually regain the ability to perform more demanding movements safely.

Which popular exercises should you skip during recovery?

Several common exercises pose specific risks after joint replacement and should be avoided or modified during early recovery:

  • Deep squats and lunges exceeding 90 degrees – These movements force excessive flexion that risks dislocation or tissue damage before your joint has stabilized, particularly dangerous in the first three months
  • Heavy or deep leg presses – The combination of high resistance and deep range of motion creates compressive and shearing forces that healing tissue cannot safely absorb
  • Extreme yoga poses – Positions like pigeon pose, lotus position, or deep hip openers require flexion and rotation beyond safe ranges for newly replaced joints
  • Contact sports and unpredictable movements – Activities like basketball, football, or martial arts involve sudden directional changes and potential impacts that can compromise your surgical outcome
  • Twisting exercises – Rotational movements in tennis, golf swings, and certain dance moves create shearing forces at the joint that healing structures cannot handle effectively
  • High-impact cardio – Running, plyometrics, jumping exercises, and step aerobics generate repetitive impact that can accelerate prosthesis wear and prevent proper tissue healing

High-impact activities should typically be avoided for at least six months after surgery, with some surgeons recommending permanent avoidance to maximize prosthesis longevity. Most other restrictions gradually lift between three and six months post-surgery, though this timeline varies based on your healing progress, the type of prosthesis used, and your surgeon’s specific approach. Working closely with your medical team ensures you understand which modifications apply to your individual situation and when you can safely reintroduce more demanding movements.

How do you know when you’re ready to progress your exercise routine?

Recognizing the right time to advance your exercise program requires attention to several key indicators:

  • Pain-free performance of current exercises – You should complete your existing routine without sharp pain, persistent aching, or protective movement patterns that indicate your body is struggling
  • Achievement of recovery milestones – Typical markers include walking without assistance (4-6 weeks), returning to daily activities pain-free (8-12 weeks), and achieving full safe range of motion (12-16 weeks)
  • Medical team confirmation – Your surgeon assesses bone integration around the prosthesis through physical examination and sometimes imaging to verify structural readiness for increased demands
  • Appropriate post-exercise response – Mild muscle soreness resolving within a day signals healthy adaptation, whereas sharp pain, persistent swelling, or worsening stiffness indicates you’ve exceeded current capacity
  • Consistent movement quality – You can perform exercises with proper form throughout the full set without compensatory patterns or technique breakdown that might cause problems

Understanding the difference between normal adaptation and warning signs is crucial for safe progression. Sharp pain during movement, swelling lasting beyond a few hours, or stiffness that worsens rather than improves all suggest you should reduce intensity and consult your physiotherapist or surgeon. Working with professionals who understand post-surgical recovery helps you progress confidently—they can assess your movement quality, identify compensations that might cause problems, and design progressions that challenge you appropriately without risking your surgical outcome. Regular check-ins ensure you’re advancing at the right pace for your individual healing timeline, building strength and confidence whilst protecting your investment in surgery.
