Post-ACL Surgery: Recovery Timeline and Scar Management Tips - Orthopedics

Post-ACL Surgery


Hello, my family member just underwent surgery for a torn posterior cruciate ligament.
The doctor mentioned that the leg should not be bent for two weeks.
Does that mean rehabilitation starts only after two weeks, or should it begin the day after surgery? The doctor didn't discuss this part and only emphasized that the leg should not be straightened for two weeks.
What should we do?
Additionally, my family member has had issues with keloids after previous surgeries.
Will this type of cruciate ligament surgery pose the same problem? If so, how can we prevent it?

Hello: After cruciate ligament surgery, immobilization for two weeks is necessary to prevent ligament laxity, and isometric muscle exercises can be initiated.
Keloids should be more focused on the scar tissue of the skin and are less related to the ligaments.

More Info


After undergoing anterior cruciate ligament (ACL) surgery, it is crucial to understand the recovery timeline and proper scar management to ensure optimal healing and regain function. The recovery process can vary significantly from person to person, but there are general guidelines that can help you navigate this journey.


Recovery Timeline
1. Immediate Post-Operative Phase (Days 1-3):
- After surgery, the focus is primarily on managing pain and swelling. Ice therapy and elevation of the leg are essential during this period.

- While your family member may be advised not to bend the knee for two weeks, it is common for physical therapy to begin within the first few days post-surgery. Gentle range-of-motion exercises may be introduced to prevent stiffness, but these should be done under the guidance of a physical therapist.

2. Weeks 1-2:
- During the first two weeks, the emphasis is on protecting the surgical site and allowing the initial healing to occur. The patient may be instructed to use crutches and a brace to stabilize the knee.

- It is important to follow the surgeon's instructions regarding weight-bearing activities. Typically, partial weight-bearing may be allowed, depending on the surgical technique used.

3. Weeks 3-6:
- After the initial two weeks, physical therapy becomes more intensive. The therapist will guide the patient through exercises to improve range of motion, strength, and stability.

- Patients may begin to perform more active exercises, including straight leg raises and gentle bending of the knee, as tolerated.

4. Weeks 6-12:
- By this stage, the focus shifts to strengthening the muscles around the knee and improving functional mobility. Activities may include balance exercises and low-impact aerobic conditioning.

- Patients are typically encouraged to gradually return to daily activities and may start light sports or recreational activities, depending on their progress.

5. 3-6 Months:
- Full recovery can take anywhere from six months to a year, depending on the individual and the extent of the injury. Athletes may begin to return to their sport after a thorough evaluation by their healthcare provider.


Scar Management Tips
Scar management is an important aspect of recovery, especially for individuals prone to keloid formation or hypertrophic scars. Here are some strategies to minimize scar tissue development:
1. Keep the Incision Clean and Moisturized:
- After the surgical site has healed sufficiently, keeping the scar moisturized with silicone gel or ointments can help reduce scar formation.

2. Gentle Massage:
- Once the incision has healed, gentle massage of the scar tissue can promote blood flow and help break down collagen fibers that contribute to thick scarring.

3. Avoid Sun Exposure:
- Protect the scar from sun exposure, as UV rays can darken scars and make them more noticeable. Use sunscreen or cover the area when outdoors.

4. Monitor for Signs of Complications:
- If there are signs of excessive redness, swelling, or pain around the scar, it is essential to consult with a healthcare provider to rule out infection or other complications.

5. Consult a Specialist:
- If your family member has a history of keloid scarring, it may be beneficial to consult with a dermatologist or plastic surgeon who specializes in scar management for tailored advice.


Conclusion
In summary, while the initial two weeks post-ACL surgery may involve limited movement, physical therapy typically begins shortly after surgery to promote healing and prevent stiffness. Scar management is crucial, especially for those with a history of problematic scarring. Following the surgeon's and physical therapist's recommendations will be key to a successful recovery. If there are any concerns about the recovery process or scar formation, do not hesitate to reach out to the healthcare team for guidance.
