These exercises are typically performed in a progressive manner, starting with gentle movements and gradually increasing the range of motion and resistance as the knee heals and strengthens.

Active Knee Bending

Active knee bending involves actively bending the knee against gravity without assistance.

  • Sit to Stand:Start by sitting in a chair with feet flat on the floor. Slowly stand up, bending your knee to lift your body weight. Repeat 10-15 times.

Pain Management

Managing pain after ACL surgery is crucial to facilitate knee bending exercises and promote recovery. Here are some effective strategies:

Non-prescription Pain Relievers:

  • Over-the-counter (OTC) pain relievers like ibuprofen or acetaminophen can effectively reduce pain and inflammation.
  • Use these medications as directed and consult a healthcare professional before combining multiple OTC pain relievers.

Prescription Pain Relievers:

  • For severe pain, prescription opioids may be prescribed, but these should be used cautiously due to potential side effects.
  • Follow the doctor’s instructions carefully and avoid exceeding recommended dosages.

Alternative Therapies:

  • Ice Therapy:Applying ice packs to the knee can numb pain and reduce swelling.
  • Heat Therapy:Applying heat packs or taking warm baths can relax muscles and improve circulation, promoting pain relief.

Return to Activity

Returning to normal activities after ACL surgery depends on several factors, including knee bending ability, pain levels, and overall recovery progress. It’s crucial to follow your surgeon’s instructions and gradually increase activity levels to avoid reinjury.

Initially, you may experience stiffness and pain, limiting your knee bending range. As you progress through rehabilitation, you’ll gradually regain motion and strength, allowing you to perform everyday activities such as walking, climbing stairs, and squatting.

Guidelines for Gradually Increasing Activity Levels

  • Start with light activities like walking and gradually increase distance and intensity.
  • Listen to your body and rest when needed to prevent pain and swelling.
  • Avoid high-impact activities, pivoting, or sudden changes in direction until cleared by your doctor.
  • Use assistive devices like crutches or a knee brace if recommended.
  • Engage in regular strengthening exercises to improve knee stability and function.

Avoiding Reinjury

  • Warm up before any activity and cool down afterward.
  • Use proper form when performing exercises or lifting objects.
  • Strengthen the muscles around your knee to provide support and stability.
  • Avoid overexertion and allow your knee to heal at its own pace.
  • If you experience any pain, swelling, or instability, stop the activity and consult your doctor.
