Anterior cruciate ligament tear with associated fracture?


Hello Doctor: At the end of January this year, I suffered a torn anterior cruciate ligament and a fracture in my right knee due to a car accident.
I had a metal plate inserted, and the doctor advised me to keep it immobilized for a month without bending or putting weight on it.
After a month, the immobilization was removed, and I started rehabilitation.
About a month and a half later, I stopped using crutches and began to walk with weight-bearing.
It has been almost three months since then.
I would like to know if this could affect the healing of the bone.
Currently, I still have a slight limp when walking, and I feel that my knee tends to tilt inward while walking.
My leg does not fully extend, and when both legs are straightened, the curvature of the knee on the injured leg is less than that of the other leg.
I can only gradually stretch it out.
I am now more concerned about the following: 1.
When lying flat with my legs straight, my knee feels slightly elevated.
2.
The arc of my lower leg when walking is less than that of the other leg, and sometimes, due to certain positions or when kicking forward, I experience a pulling pain in the bone on the inner side of my lower leg below the knee.
3.
I can slowly stretch my knee to its limit, like stretching, but after a while, it still tends to revert back.
4.
I cannot stand on the injured leg with it fully extended for more than three seconds; I need to keep my knee slightly bent to exceed three seconds.
Could these issues be due to my early cessation of using crutches, or do I need further rehabilitation? I would appreciate your guidance.
Thank you!

Hello: In response to your question, rehabilitation therapy is necessary after an anterior cruciate ligament (ACL) tear with associated fracture surgery.
The fact that you can walk without crutches indicates that your function has mostly recovered.
However, since you still cannot fully extend the affected leg, your function has not completely returned.
It is recommended to actively pursue rehabilitation.
If there is no improvement, please consult your original surgeon, as they are most familiar with your condition.
Wishing you a speedy recovery!

Recovering from an ACL tear can be a complex process, and it’s understandable to have concerns about your healing and rehabilitation. Based on your description, it seems like you are experiencing some common post-operative issues that many patients face after ACL reconstruction. Let’s address your concerns one by one and provide some insights into the recovery process.

1. Impact of Early Weight Bearing: You mentioned that you started bearing weight and walking without crutches about six weeks post-surgery. Generally, early weight-bearing can be beneficial for recovery, but it must be done cautiously and under the guidance of your healthcare provider. If your doctor advised you to start walking without crutches, it likely means that your bone and soft tissue were healing adequately. However, if you feel pain or instability while walking, it’s essential to communicate this to your physical therapist or orthopedic surgeon. They can assess your gait and determine if any adjustments to your rehabilitation plan are necessary.

2. Knee Alignment and Gait Issues: The inward deviation of your knee while walking, along with the inability to fully straighten your leg, can be attributed to several factors, including muscle weakness, tightness in the surrounding muscles, or even proprioceptive deficits. After an ACL injury, it’s common for the muscles around the knee to weaken due to disuse, which can lead to compensatory movement patterns. Engaging in a structured rehabilitation program that focuses on strengthening the quadriceps, hamstrings, and calf muscles, as well as improving flexibility, can help address these issues.

3. Knee Extension and Flexibility: The difficulty in fully extending your knee and the sensation of your knee "bouncing back" after stretching are indicative of potential stiffness or tightness in the joint or surrounding tissues. This is a common occurrence after knee surgery. Regular stretching and strengthening exercises, as prescribed by your physical therapist, are crucial for regaining full range of motion. It’s important to be patient, as regaining flexibility can take time.

4. Pain and Discomfort: The pain you experience in the lower leg, especially during certain movements, could be due to several reasons, including muscle strain, overcompensation, or even irritation of the soft tissues around the knee. If the pain persists or worsens, it’s advisable to seek a professional evaluation to rule out any complications.

5. Importance of Rehabilitation: Rehabilitation is a critical component of recovery from an ACL tear. It’s not just about regaining strength and flexibility; it’s also about restoring function and stability to the knee. A well-structured rehabilitation program typically includes phases that focus on reducing swelling, restoring range of motion, strengthening the muscles around the knee, and eventually returning to sport-specific activities. It’s essential to follow your physical therapist's guidance and not rush the process, as doing too much too soon can lead to setbacks.

In conclusion, while your concerns are valid, many of the issues you’re experiencing are common among individuals recovering from ACL injuries. It’s crucial to maintain open communication with your healthcare team, adhere to your rehabilitation program, and be patient with your recovery process. If you have any doubts or if your symptoms persist, don’t hesitate to seek further evaluation from your orthopedic surgeon or physical therapist. They can provide tailored advice and adjustments to your rehabilitation plan to ensure you’re on the right track to recovery.
