Consultation regarding patellar valgus?


Hello, doctor.
My knee has had pain issues since fifteen years ago when I suddenly experienced severe pain while rushing up the stairs one day in college.
The pain has been recurring; sometimes it’s fine, but other times, going up the stairs can trigger sudden severe pain.
I have seen orthopedic specialists for several years without improvement.
It was only two years ago that I decided to consult a rehabilitation specialist, who diagnosed me with "patellar malalignment." The outpatient doctor advised me to "avoid using squat toilets, refrain from squatting or kneeling, and take the elevator whenever possible instead of using the stairs." Since that consultation, I have been using a sitting toilet and have avoided squatting completely; I only allow myself to do a slight half-squat when picking things up, tying my shoes, or cleaning.
However, my mother keeps nagging me, saying, "If you don’t squat or use the stairs, your knees will get worse and weaker." I would like to ask the doctor: (1) Is my mother's perspective correct? Should I occasionally squat fully or walk up the stairs? (2) Can I ride a bicycle with patellar malalignment? Can I hike on mountain trails? (3) Can patellar malalignment be treated without surgery? (4) Is it possible to have children with patellar malalignment? Will pregnancy and carrying a child put too much strain on my knees? (5) Should I wear a knee brace? (Which type of knee brace is most suitable?) (6) Are there any exercises that are more suitable for someone with patellar malalignment? I apologize for the many questions, and I appreciate the doctor’s responses to each one.
Thank you.

Patellar valgus is merely a sign and may not necessarily be the cause of pain.
It is recommended to undergo more detailed examinations and diagnoses before proceeding with treatment and appropriate exercises.

More Info


Understanding patellar malalignment, particularly conditions like patellar tilt or patellar tracking issues, can be complex, especially for patients who have been experiencing knee pain for an extended period. Your experience of sudden knee pain after rushing up the stairs and the subsequent diagnosis of "patellar malalignment" is not uncommon. Let's address your questions one by one.

1. Should you squat or use stairs?
Your mother's concern about avoiding squatting and stairs is rooted in a common belief that avoiding these activities can prevent further damage. However, it's essential to balance activity with caution. While it's true that excessive squatting or stair climbing can exacerbate pain in individuals with patellar malalignment, complete avoidance may lead to muscle weakness and decreased function over time. Engaging in modified activities, such as partial squats or using stairs at a comfortable pace, can help maintain strength and mobility. It’s advisable to consult your physical therapist to develop a tailored exercise plan that considers your pain levels and functional abilities.

2. Can you ride a bike or hike?
Cycling can be a beneficial low-impact exercise for individuals with patellar malalignment, as it strengthens the quadriceps without putting excessive stress on the knee joint. Hiking, on the other hand, depends on the terrain and your current knee condition. If the trails are well-maintained and you can manage the elevation changes without pain, it may be feasible. Always listen to your body and avoid activities that cause pain.

3. Can patellar malalignment be treated non-surgically?
Yes, many cases of patellar malalignment can be managed non-surgically through physical therapy, strengthening exercises, and activity modifications. A physical therapist can guide you through exercises that strengthen the quadriceps, hamstrings, and hip muscles, which can help improve patellar tracking. Additionally, modalities like ice, ultrasound, or electrical stimulation may be beneficial in managing pain and inflammation.

4. Can you have children?
Having patellar malalignment does not inherently prevent you from having children. However, pregnancy and the physical demands of caring for a newborn can place additional stress on your knees. It's crucial to maintain a healthy weight and engage in safe exercises during pregnancy to support your knee health. Discussing your concerns with your obstetrician and a physical therapist can help you develop a plan to manage any potential knee issues during and after pregnancy.

5. Should you wear a knee brace?
Wearing a knee brace can provide support and stability, particularly during activities that may exacerbate your symptoms. A patellar stabilizing brace may be beneficial, as it helps keep the patella in alignment. However, it’s essential to consult with your healthcare provider or physical therapist to determine the most appropriate type of brace for your specific condition.

6. What exercises are suitable for patellar malalignment?
Low-impact exercises are generally recommended for individuals with patellar malalignment. These can include swimming, cycling, and using an elliptical machine. Strengthening exercises focusing on the quadriceps, hamstrings, and hip abductors are particularly beneficial. Your physical therapist can provide a tailored exercise program that emphasizes proper form and technique to minimize stress on the knee.

In summary, managing patellar malalignment involves a combination of activity modification, targeted exercises, and possibly the use of supportive devices like knee braces. It’s essential to work closely with your healthcare team to develop a personalized plan that addresses your specific needs and concerns. Remember, maintaining open communication with your physical therapist and orthopedic specialist will help you navigate your condition effectively and improve your quality of life.
