Patellar Malalignment: Concerns and Management Strategies - Rehabilitation

Patellar valgus related issues?


Hello, doctor.
I was previously diagnosed with patellar malalignment by a rehabilitation physician, who advised me to avoid squatting and kneeling.
I used to use squat toilets when going out, but since my knee started to hurt, I can only use sitting toilets now.
The action of "kneeling" isn't a big problem as long as I don't do it for too long, but occasionally, due to work or cleaning needs, if I have to "squat," my knee becomes very uncomfortable for several days.
I have a few questions:
1.
Currently, I avoid squatting whenever possible because my knee feels tight.
However, my mother believes that if I avoid squatting altogether, my knee will only become tighter and weaker over time, and she encourages me to squat occasionally.
Is my mother's perspective correct? If not, how can I explain this to her?
2.
Am I never going to be able to squat or kneel again in my life? Or is it actually okay to squat and kneel occasionally?
3.
Does any squatting or kneeling action lead to wear on the patella? Or is it not a big issue if the duration is short?
4.
I am 35 years old and considering having children, but I know that pregnancy will cause my belly to grow large and heavy.
Given my patellar malalignment issue, can I still get pregnant?
5.
Is there a solution for patellar malalignment? What can be done to improve this condition?
6.
Should I seek help from other specialties regarding my patellar malalignment? (I have only seen orthopedic and rehabilitation specialists so far.)
I hope you can address these questions one by one.
Thank you.

1 & 2.
Short-term squatting should not cause significant effects, but it is advisable to incorporate thigh strength training and use assistive devices to enhance knee joint stability and alleviate symptoms.
3.
Pregnancy may lead to increased joint laxity, resulting in exacerbated pain; however, it generally does not contraindicate pregnancy.
Similar to the previous point, appropriate treatments can help alleviate discomfort, but it should still be assessed based on individual circumstances.
4.
In addition to the conservative treatment methods mentioned above, surgical intervention may be considered for severe cases.
5.
Patellar malalignment is treated by both orthopedic and rehabilitation specialists.

Understanding patellar malalignment, particularly conditions like patellar tilt or patellar subluxation, is crucial for managing knee pain and maintaining joint function. Your concerns about your diagnosis of patellar malalignment and the associated symptoms are valid, and I will address each of your questions in detail.

1. Avoiding Squatting Movements: Your mother's suggestion to occasionally perform squatting movements to prevent stiffness is partially valid. While it's essential to avoid movements that exacerbate your pain, completely avoiding squatting can lead to decreased strength and flexibility in the knee joint over time. Gentle, controlled squatting can help maintain mobility and strength, but it should be done cautiously and ideally under the guidance of a physical therapist. You can explain to your mother that while some movement is beneficial, it must be balanced with pain management and the need to avoid exacerbating your condition.

2. Can You Squat or Kneel Again?: It's not that you will never be able to squat or kneel again, but it may require a gradual approach. Many individuals with patellar malalignment can return to these activities with proper rehabilitation and modifications. Start with shallow squats or kneeling on soft surfaces, and listen to your body. If pain persists, consult your healthcare provider for tailored advice.

3. Impact of Squatting and Kneeling on Patellar Wear: The concern about wear and tear on the patella is valid. Activities that place excessive stress on the knee joint can lead to cartilage wear over time, especially if performed incorrectly or excessively. However, short durations of squatting or kneeling, when done with proper form and without pain, are generally not harmful. It's essential to focus on strengthening the muscles around the knee to provide better support and stability.

4. Pregnancy Considerations: Being 35 and considering pregnancy is a significant life decision. While patellar malalignment can complicate physical activity during pregnancy, it does not inherently prevent you from becoming pregnant. However, as your belly grows, it may alter your center of gravity and put additional stress on your knees. It's advisable to consult with your obstetrician and possibly a physical therapist specializing in prenatal care to develop a plan that accommodates your knee condition while ensuring a healthy pregnancy.

5. Can Patellar Malalignment Improve?: Yes, patellar malalignment can improve with appropriate interventions. Physical therapy focusing on strengthening the quadriceps, hamstrings, and hip muscles can help stabilize the patella. Stretching tight muscles, particularly the iliotibial band and calf muscles, is also beneficial. In some cases, orthotics or knee braces may be recommended to improve alignment during activities.

6. Seeking Additional Help: If you have not already, consider consulting a sports medicine specialist or a physical therapist with experience in knee conditions. They can provide a comprehensive assessment and tailored rehabilitation program. Additionally, if conservative measures do not yield improvement, an orthopedic surgeon specializing in knee conditions may offer surgical options to correct malalignment.

In summary, while patellar malalignment can be a challenging condition, with appropriate management strategies, including physical therapy, activity modification, and possibly surgical intervention, many individuals can achieve significant improvement. It’s essential to listen to your body, seek professional guidance, and maintain open communication with your healthcare providers about your concerns and goals.
