Patellar fracture - postoperative
Hello, Doctor.
Last month, I inquired about patellar fractures (#142575).
It has been 2.5 months since my surgery, and I have had my knee brace removed.
I can currently bend my knee to 120 degrees and am undergoing water therapy and rehabilitation.
I would like to ask you about a few concerns.
Last week, after removing the knee brace, I noticed that my knee makes a sound when walking.
During the process of straightening my knee, I feel a slight sliding of the joint bones.
When walking on a slightly inclined surface, I sometimes experience a feeling of weakness in my legs.
During rehabilitation, the therapist mentioned that this might be due to weakness in my quadriceps.
1.
Is it common for the knee to vibrate during the recovery process after a patellar fracture? Is this due to weakness in the quadriceps, or could it be related to the healing process at the fracture site where the bone callus is not smooth? Or could there be other reasons?
2.
I found a quadriceps training video online (https://www.youtube.com/watch?v=H0OAZBjGlvA).
During my hospital stay, I was only taught the first phase of the exercises.
I am currently following the video to train my quadriceps through phases one to five.
Is this correct?
Thank you, Doctor, for your attention and response.
Thank you!

1.
After a patellar fracture surgery, if the muscles are not used for a period of time, they may become weaker.
However, with gradual rehabilitation therapy, they usually recover.
The vibrations you mentioned may be due to insufficient muscle strength.
If the surface of the fracture site is uneven, it can produce friction sounds and even cause pain.
2.
Training the quadriceps is usually quite simple.
You can sit on a higher chair, allowing your knee joint to bend to 90 degrees, with your lower leg hanging down, and then extend your knee until it is level.
Repeat this slowly for about ten minutes, three times a day, and gradually your muscle strength will recover.
Before the fracture has completely healed, you should avoid putting too much strain on it or using weights on your lower leg, as this can increase the stress on the patella and may lead to a re-fracture.

More Info
Post-operative recovery from a patellar fracture can be a complex process, and it’s essential to understand the various factors that can influence your rehabilitation. Based on your description, it seems you are experiencing some common post-operative symptoms, and I will address your concerns in detail.
1. Knee Noise and Sensation: It is not uncommon for patients recovering from a patellar fracture to experience noises in the knee joint, such as clicking or popping sounds. These sounds can occur due to several reasons. One possibility is that the quadriceps muscle, which plays a crucial role in stabilizing the knee, may still be weak. A lack of strength in the quadriceps can lead to improper tracking of the patella (kneecap) during movement, resulting in these noises. Additionally, the healing process of the fracture site may involve the formation of scar tissue or bone callus, which can also contribute to sensations of grinding or slipping during knee extension.
2. Quadriceps Strength: Your rehabilitation therapist's assessment that the quadriceps may be weak is valid. Strengthening this muscle is vital for knee stability and function. Weakness in the quadriceps can lead to a feeling of instability or “softness” in the knee, especially on uneven surfaces. It is crucial to engage in a structured rehabilitation program that focuses on strengthening the quadriceps and improving overall knee function.
3. Exercise Progression: The video you referenced for quadriceps training appears to be a good resource for progressive strengthening exercises. It is essential to follow a structured program that gradually increases in intensity and complexity. Ensure that you are performing exercises correctly to avoid further injury. If you have only been taught the first stage of exercises during your hospital stay, it may be beneficial to consult your physical therapist to ensure you are ready to progress to the next stages safely.
4. Monitoring Symptoms: While some noise and sensations in the knee can be normal during recovery, it is essential to monitor these symptoms closely. If you experience significant pain, swelling, or instability, it may indicate that you need to adjust your rehabilitation approach or consult your orthopedic surgeon for further evaluation.
5. Importance of Rehabilitation: Continuing with physical therapy is crucial. Your therapist can provide tailored exercises that focus on improving strength, flexibility, and range of motion. They can also help you with proprioceptive training, which is essential for regaining balance and coordination in the knee.
6. Long-term Recovery: Recovery from a patellar fracture can take several months, and it is not uncommon for patients to experience lingering symptoms even after the initial healing phase. Patience and adherence to your rehabilitation program are key to achieving the best possible outcome.
7. Consulting Specialists: If your symptoms persist or worsen, it may be beneficial to consult with your orthopedic surgeon or a sports medicine specialist. They can provide additional insights and may recommend imaging studies, such as an MRI, to assess the healing of the fracture and the condition of surrounding soft tissues.
In summary, while some noise and sensations in the knee can be expected during recovery from a patellar fracture, it is essential to focus on strengthening the quadriceps and following a structured rehabilitation program. Keep an open line of communication with your healthcare providers, and do not hesitate to seek further evaluation if your symptoms cause concern. Your proactive approach to your recovery will be crucial in regaining full function and returning to your desired activities.
