Improving Knee Flexion After Severe Injury: Options and Hope - Orthopedics

Knee flexion issues?


Hello, doctor...
At the end of last year, I was involved in a serious car accident that resulted in an open fracture of my left thigh and some bone fragments in my knee.
I have been undergoing rehabilitation for the past seven months, and last month I even had a surgery to release the tightness in my knee.
However, the results have been disappointing, and my current range of motion is only about sixty degrees.
I would like to ask, is it possible that I will have to live like this for the rest of my life? My primary physician mentioned a potential option of knee ligament surgery to lengthen the ligaments, but it would also make them thinner (please forgive my lack of expertise; I didn't note the name of the surgery, but my physician referred to it as the "V-Y procedure" because the ligament is cut in a V-Y shape).
I would like to know if there are any other medical options available to improve my knee flexion.
At the very least, I want to achieve a 90-degree bend; is this an unattainable dream for me?

Your condition may be due to an extension contracture of the knee joint following a fracture, or a quadriceps muscle contracture, which means the knee is fixed in an extended position and cannot flex properly.
This may be caused by adhesions or shortening of the quadriceps muscle.
Therefore, a muscle-tendon lengthening procedure (such as VY lengthening or tendon lengthening) may be necessary, which can assist in improving knee flexion.
With aggressive rehabilitation, it is likely that the desired outcome can be achieved.

I'm sorry to hear about your severe injury and the challenges you're facing with knee flexion. Recovering from such significant trauma, especially involving open fractures and joint injuries, can be a long and complex process. Your determination to regain mobility is commendable, and there are several options and considerations that may help you improve your knee flexion.

Firstly, it's essential to understand that the recovery process after a severe knee injury can vary significantly from person to person. Factors such as the extent of the injury, the type of surgical interventions performed, and individual healing responses all play a crucial role in determining recovery outcomes. In your case, with a current flexion of only 60 degrees after seven months of rehabilitation and a recent procedure to release the knee, it’s understandable to feel frustrated and concerned about your long-term mobility.

One of the most critical aspects of rehabilitation is the ongoing physical therapy. Since you have already been engaged in rehabilitation for several months, it may be beneficial to reassess your current therapy regimen. Working closely with a physical therapist who specializes in post-surgical rehabilitation can provide you with tailored exercises and strategies to improve your knee flexion. They can also help you manage pain and stiffness, which are common after such injuries. Techniques such as manual therapy, stretching, and strengthening exercises for the quadriceps and hamstrings can be particularly beneficial.

Regarding the surgical option your doctor mentioned, often referred to as a "V-Y plasty" or "V-Y advancement," this procedure can indeed help lengthen the ligaments around the knee, potentially improving range of motion. However, it is essential to weigh the risks and benefits of any surgical intervention carefully. Discussing this option in detail with your orthopedic surgeon can help clarify whether this procedure is appropriate for your specific situation and what outcomes you might realistically expect.

In addition to surgical options, there are other non-invasive treatments that may assist in improving your knee flexion. These include:
1. Continuous Passive Motion (CPM) Machines: These devices can help gently move your knee through its range of motion, which may promote healing and flexibility.

2. Hydrotherapy: Exercising in water can reduce the strain on your knee while allowing you to work on your range of motion and strength.

3. Electrical Stimulation: This can help activate muscles around the knee, promoting strength and potentially improving range of motion.

4. Pain Management: If pain is limiting your ability to engage in rehabilitation, discussing pain management strategies with your healthcare provider is crucial. This may include medications, injections, or alternative therapies.

5. Bracing: While you mentioned discomfort with braces, a well-fitted brace can provide support and stability, allowing you to engage more effectively in rehabilitation exercises.

6. Nutritional Support: Ensuring you have adequate nutrition, including sufficient protein and vitamins, can support healing and recovery.

Lastly, it’s important to maintain realistic expectations. While achieving full range of motion may be challenging, many individuals can improve their knee flexion significantly with the right interventions and dedication to rehabilitation. Setting incremental goals, such as aiming for 70 degrees, then 80 degrees, can help keep you motivated.

In conclusion, while the journey to regain knee flexion after a severe injury can be daunting, there are various options available to you. Collaborating closely with your healthcare team, including orthopedic surgeons and physical therapists, will be crucial in developing a comprehensive plan tailored to your needs. Remember, persistence and patience are key in the recovery process, and many individuals have successfully improved their knee function even after significant injuries.
