Inquiry about rehabilitation after patellar fracture surgery?


Hello, Doctor.
I underwent surgery for a patellar fracture in early July.
The X-ray showed a crack in the middle, and the doctor said that it could be fixed with steel pins, without the use of wires.
It has now been four months, and my knee still feels tight when walking, and I can only bend it about 90 degrees.
The doctor advised me to walk more, but I am concerned that not engaging in bending rehabilitation now may affect my knee's future flexibility.
Therefore, I would like to ask a few questions:
1.
Around October, I started to press my leg inward to increase the degree of bending.
Is this approach feasible? Is it normal to feel a tearing sensation in the area where the knee connects to the lower leg during this process?
2.
My knee still appears swollen.
What methods can improve this condition, and is this phenomenon reasonable? (I am worried that excessive bending may be causing the swelling, so I have been cautious about bending it too much for the past two weeks, only walking normally.)
3.
When is it appropriate to see a rehabilitation specialist? Is it better to consult a rehabilitation specialist or to practice bending on my own according to my recovery progress?
4.
Is it normal that I still cannot lift my lower leg with strength?
Thank you, Doctor, for your response.

More Info


After undergoing surgery for a patellar fracture, it is common to have concerns regarding rehabilitation and recovery. Your situation, having had surgery four months ago, indicates that you are in a critical phase of your rehabilitation. Here are some insights and answers to your questions based on medical knowledge and rehabilitation practices.

1. Self-Directed Exercises: It is generally acceptable to begin gentle exercises to increase the range of motion in your knee, such as pressing your leg inward to enhance flexion. However, if you experience a tearing sensation in the area where your knee connects to your lower leg, it is crucial to listen to your body. This sensation could indicate strain on the healing tissues. It is advisable to perform these movements within a pain-free range and to consult with your healthcare provider or physical therapist before significantly increasing the intensity of your exercises.

2. Knee Swelling: Swelling in the knee after surgery can be a normal part of the healing process, especially if you have been active. However, persistent swelling may indicate that you are overdoing it or that there is an underlying issue. To manage swelling, consider elevating your leg, applying ice, and using compression wraps as needed. If the swelling does not improve or worsens, it is essential to consult your physician to rule out complications such as fluid accumulation or infection.

3. When to See a Rehabilitation Specialist: It is advisable to see a physical therapist or rehabilitation specialist if you have not already done so. A rehabilitation professional can provide a tailored exercise program that considers your specific condition and recovery stage. They can also monitor your progress and adjust your rehabilitation plan as needed. Typically, patients are referred to rehabilitation services when they have completed the initial healing phase, which can vary but is often around 6-8 weeks post-surgery.

4. Weakness in the Lower Leg: It is not uncommon to experience weakness in the lower leg after knee surgery. This weakness can result from disuse during the recovery period and the impact of the injury on the surrounding muscles. Engaging in targeted strengthening exercises, as guided by a physical therapist, can help rebuild strength in your calf and thigh muscles. It is essential to start with low-resistance exercises and gradually increase the difficulty as your strength improves.

In summary, while it is important to remain active and work on your range of motion, it is equally crucial to do so safely and under the guidance of a healthcare professional. Rehabilitation after a patellar fracture can be a lengthy process, and patience is key. Regular follow-ups with your orthopedic surgeon and physical therapist will help ensure that you are on the right track and that any concerns, such as swelling or pain, are addressed promptly. Always prioritize your safety and well-being during your recovery journey.
