I am a long-distance runner and often participate in various road races, with my longest distance being a half marathon. I mostly train on asphalt surfaces, but I have been experiencing pain in my right knee?


I am a long-distance runner and often participate in various road races, with my longest distance being a half marathon.
I mostly train on asphalt surfaces.
I sought medical attention at a hospital due to pain in my right knee, and after an MRI, the doctor diagnosed me with grade III chondromalacia patellae.
The doctor only advised me to take glucosamine and did not prescribe any other treatments.
I would like to ask: besides taking glucosamine, are there other therapies or medications available? (I do not experience discomfort during daily activities, but occasionally feel some soreness.)

Hello: In response to your question...
The main significance of patellar chondromalacia lies in the structural changes of the patella due to injury or other non-injury-related inflammatory responses.
The mechanisms involved include not only structural alterations but also an increase in inflammatory factors.
Therefore, treatment approaches can be divided into two aspects.
One aspect focuses on structural changes, such as avoiding activities that may further injure the patellar cartilage (avoiding knee-impacting exercises) or surgical interventions (such as lateral retinacular release or tibial tuberosity elevation) to alleviate pressure on the patellar cartilage.
The other aspect involves supplementing or modifying the cartilage components in the synovial fluid, such as oral glucosamine, hyaluronic acid injections, or oral non-steroidal anti-inflammatory drugs (NSAIDs).
Many people may say they do not experience pain, only occasional discomfort; however, this indicates the presence of inflammation, and analgesic and anti-inflammatory medications still serve their purpose.
Additionally, your exercise regimen should be adjusted.
A general recommendation is to reduce your daily exercise volume by half; if symptoms persist, further reduce it by half again.
Once you maintain this reduced exercise volume for over a month without symptoms, you can gradually increase your activity level.
It is also advisable to engage in regular exercise two to three times a week, and avoid becoming a weekend warrior.

Managing patellar chondromalacia, particularly for runners, requires a comprehensive approach that goes beyond just taking supplements like glucosamine. Patellar chondromalacia, or the softening and breakdown of the cartilage on the underside of the kneecap, can be a significant concern for those who engage in high-impact activities such as running. Here are several strategies to consider for managing this condition effectively:

1. Physical Therapy
Engaging in a structured physical therapy program can be immensely beneficial. A physical therapist can design a personalized rehabilitation program focusing on strengthening the muscles around the knee, particularly the quadriceps, hamstrings, and hip muscles. Strengthening these muscles can help stabilize the knee joint and reduce the load on the patella, potentially alleviating pain and discomfort.


2. Activity Modification
While running is a beloved activity, it may be necessary to modify your running routine. Consider switching to softer surfaces, such as grass or a track, to reduce the impact on your knees. Additionally, incorporating cross-training activities like swimming or cycling can help maintain cardiovascular fitness while giving your knees a break from the repetitive stress of running.


3. Biomechanical Assessment
A thorough assessment of your running form and biomechanics can identify any abnormalities that may contribute to knee pain. This assessment can be conducted by a sports physiotherapist or a running coach who specializes in biomechanics. They may recommend adjustments to your running technique or suggest specific footwear that provides better support and alignment for your feet and knees.


4. Strength Training
Incorporating a strength training regimen that targets the lower body can enhance muscle balance and support around the knee joint. Focus on exercises that strengthen the quadriceps, hamstrings, glutes, and calves. Exercises like squats, lunges, and leg presses can be particularly effective. However, it's crucial to perform these exercises with proper form to avoid exacerbating the condition.


5. Flexibility and Stretching
Maintaining flexibility in the muscles surrounding the knee is essential. Regular stretching of the quadriceps, hamstrings, calves, and hip flexors can help prevent tightness that may contribute to knee pain. Consider integrating yoga or Pilates into your routine, as these practices promote flexibility and core strength.


6. Pain Management
While supplements like glucosamine can be helpful, other pain management strategies may include non-steroidal anti-inflammatory drugs (NSAIDs) for acute pain relief. Always consult with a healthcare provider before starting any medication. Additionally, applying ice to the knee after running can help reduce inflammation and alleviate discomfort.


7. Gradual Return to Running
If you’ve taken a break from running due to pain, it’s essential to return gradually. Start with shorter distances and lower intensity, and pay attention to how your knee responds. Gradually increase your mileage and intensity only when you feel comfortable and pain-free.


8. Consider Orthotics
If your foot mechanics contribute to knee pain, custom orthotics may provide the necessary support and alignment. A podiatrist can evaluate your foot structure and recommend orthotics that can help improve your running mechanics.


9. Surgical Options
In severe cases where conservative treatments fail, surgical options may be considered. Procedures such as arthroscopy to smooth the cartilage or realignment of the patella may be options, but these are typically reserved for cases that do not respond to other treatments.


Conclusion
In summary, managing patellar chondromalacia involves a multifaceted approach that includes physical therapy, activity modification, strength training, and proper pain management. While supplements can play a role, they should not be the sole focus of treatment. It’s essential to listen to your body and consult with healthcare professionals to develop a comprehensive plan tailored to your specific needs as a runner. By taking proactive steps, you can continue to enjoy running while minimizing the risk of further knee issues.
