Dos and don'ts after ACL surgery
The road to recovery after ACL surgery is not always smooth, but following the right practices can make all the difference. Knowing what to do and what to avoid is crucial for a smooth and successful ACL surgery recovery.
In this blog, we’ll explore the common bad signs after ACL surgery, along with expert tips from renowned knee surgeon Dr. Rik Kundra—to help you stay on track and regain your mobility with confidence.
What is ACL surgery?
ACL surgery, or Anterior Cruciate Ligament reconstruction, is a common orthopedic procedure used to repair or replace a torn ACL — one of the key ligaments that helps stabilize the knee joint.
Whether caused by sports injuries, accidents, or sudden twists, a torn ACL can severely affect your mobility and quality of life.
While ACL surgery is generally successful, Dr. Rik emphasizes that your outcome heavily depends on how well you manage your recovery. Recognizing bad signs after ACL surgery and seeking timely medical attention are crucial steps to ensure a successful outcome.
How long does it take to recover from ACL surgery?
Recovery isn’t one-size-fits-all, but here’s a general timeline:
⏱️ Week 1–2: Managing pain and swelling, beginning gentle movements
⏱️ Week 3–6: Starting light physical therapy, improving range of motion
⏱️ Month 2–4: Building strength and stability
⏱️ Month 4–6: Resuming low-impact activities
⏱️ Month 6–12: Return to sports or full activity (with clearance)
Patience and discipline go a long way in ensuring your ACL surgery recovery stays on track.
What can I do to maximize my ACL surgery recovery?
To promote optimal healing and return to your regular activities, here are essential dos recommended by Dr. Rik Kundra:
✅ Begin prehabilitation exercises with a physiotherapist before surgery to build strength and enhance outcomes.
✅ Incorporate low-impact cardio—like using a cross trainer or stationary bike—to maintain joint mobility before and after surgery.
✅ Learn proper crutch techniques prior to surgery to support safe post-op movement.
✅ Maintain a healthy diet, minimize alcohol, and quit smoking to aid tissue healing.
✅ Schedule your first post-op physiotherapy session within a week after surgery.
✅ Use cold therapy (if available) to manage swelling and discomfort in the early days.
✅ Use crutches for as long as needed, bearing weight gradually as advised by your physiotherapist.
✅ Keep the surgical wound dry and covered for at least two weeks to prevent infection.
✅ Elevate your leg by placing pillows under the heel to reduce swelling while resting or sleeping.
✅ Most importantly, always follow the guidance of your care team—your physiotherapist, surgeon, and nursing staff.

What should I avoid whilst my ACL surgery recovery?
It’s essential to understand that recovery after ACL surgery is a gradual, staged process that may take up to 12 months before you can safely pivot and move your knee as you did before.
During this time, you should avoid the following:
❌ Skipping physiotherapy sessions or not following your rehab plan
❌ Engaging in non-approved physical activities or sports
❌ Allowing your knee to become stiff due to prolonged immobility
❌ Participating in movements or sports that make your knee feel unstable
Most importantly, Dr. Rik advises avoiding thinking that you’ll be fine and getting back to your normal activities sooner than advised—you’ll be more likely to re-injure your knee and delays your overall recovery progress.

FAQ's
After ACL surgery, bad signs after ACL surgery include persistent swelling, severe pain, limited range of motion, instability, fever, or redness around the incision. Difficulty bearing weight or unusual noises in the knee also warrant attention. Always consult your surgeon promptly if any of these symptoms occur during recovery.
After ACL surgery, worry if you experience severe pain, excessive swelling, fever, pus from the incision, inability to move the knee, or a popping sensation. These could indicate infection, blood clots, or graft failure. Promptly consult your surgeon to avoid complications and ensure proper recovery.
Symptoms of a failed ACL surgery include persistent knee instability, swelling, pain during activity, limited range of motion, and difficulty bearing weight. You may also experience a popping sensation, weakness, or giving way of the knee. These bad signs after ACL surgery suggest graft failure, improper healing, or other complications requiring medical evaluation.
After ACL surgery, avoid putting weight on the leg too soon, skipping physiotherapy, sudden twisting or pivoting, and high-impact activities. Don’t ignore pain or swelling, and avoid prolonged sitting without elevating the leg. Smoking and poor nutrition can also delay healing. Follow your surgeon’s and physiotherapist’s instructions carefully.
Walking too much after ACL surgery can strain the healing ligament, increase swelling, and delay recovery. Following your surgeon’s rehabilitation plan and gradually increasing activity levels is essential. Overexertion may compromise surgical outcomes and can be one of the bad signs after ACL surgery, so rest, proper physiotherapy, and controlled movement are crucial for optimal healing and long-term knee stability.
In the first week after ACL surgery, focus on rest, icing, elevation, and pain management. Begin gentle range-of-motion exercises and follow your physiotherapist’s guidance. Keep the leg elevated, use crutches as instructed, and avoid putting weight on the knee. Attend follow-up appointments to monitor healing and prevent complications.
Loose surgical screws in the knee may cause pain, swelling, instability, or a grinding sensation. A reduced range of motion or a clicking noise when moving could be signs of an issue, which can be confirmed with imaging tests like X-rays or CT scans. Consult your orthopedic surgeon promptly if symptoms appear.
After ACL surgery, avoid high-impact activities like running, jumping, pivoting, or twisting movements. Refrain from sports, heavy lifting, and sudden directional changes. Limit stair climbing and prolonged standing. Follow your physiotherapist’s guidelines strictly to prevent strain, re-injury, or delayed healing during the recovery and rehabilitation. Ignoring these precautions may lead to bad signs after ACL surgery, such as swelling, instability, or pain.
