Rehabilitation Challenges After Femur Fracture: Knee Flexibility Issues - Rehabilitation

More Info

---

Rehabilitation after a femur fracture can be a challenging process, especially when it comes to regaining knee flexibility. Your situation, having undergone surgery three months ago, is not uncommon, as many patients experience stiffness and difficulty in achieving full range of motion post-surgery. Let’s address your concerns one by one.

1. Knee Tightness and Swelling: The tightness and noticeable swelling above your left knee compared to the right knee can indeed be related to your inability to bend the knee fully. After a fracture, especially in the femur, the surrounding soft tissues, including muscles, tendons, and ligaments, can become stiff due to immobilization and disuse. This stiffness can lead to a feeling of tightness when attempting to bend the knee. Additionally, swelling can contribute to discomfort and limit your range of motion. It's essential to manage this swelling through elevation, ice application, and possibly compression to help reduce the tightness.

2. Pain During Passive Stretching: The pain you experience when attempting to push your knee into a more flexed position could be due to several factors. First, the surgical site may still be sensitive, and the surrounding tissues may not have fully healed. When you apply pressure to bend the knee, it can irritate the area around the fracture site, causing discomfort. This is not uncommon, and as you noted, the pain tends to decrease with sustained pressure. This phenomenon can be attributed to the body’s response to stretching and the gradual adaptation of the tissues involved.

3. Numbness and Sensation Changes: The numbness and altered sensation in your left leg, particularly below the knee, could be a result of nerve irritation or damage during the injury or surgery. Reduced activity can exacerbate these symptoms, as muscles and nerves may not function optimally without regular movement. To improve this, it's crucial to engage in gentle, progressive exercises that promote circulation and nerve function. Physical therapy can be beneficial in this regard, as a therapist can provide targeted exercises to enhance sensation and mobility.

4. Physical Therapy Techniques: If your current physical therapy regimen feels insufficient, it may be time to discuss additional treatment options with your therapist. Beyond heat and electrical stimulation, consider incorporating the following:
- Active Range of Motion Exercises: Gradually work on bending and straightening your knee actively, even if it’s just a small range at first.

- Strengthening Exercises: Focus on strengthening the quadriceps and hamstrings, as stronger muscles can support better knee function.

- Manual Therapy: Techniques such as joint mobilization or soft tissue massage performed by a skilled therapist can help alleviate stiffness and improve range of motion.

- Aquatic Therapy: If available, exercising in water can reduce the load on your knee while allowing for more movement.

- Functional Activities: Gradually incorporate functional movements like standing, walking, and climbing stairs to promote overall mobility.

In summary, rehabilitation after a femur fracture requires patience and a multifaceted approach. It’s essential to communicate openly with your physical therapist about your progress and any concerns you have regarding pain or stiffness. They can adjust your treatment plan to better suit your needs and help you achieve your rehabilitation goals. Remember, recovery is a gradual process, and with consistent effort, you can regain your knee flexibility and overall function.
