Knee problems


Hello Doctor: Recently, I had inflammation in my knee and an X-ray showed signs of wear.
I have been following the exercises my doctor recommended to strengthen my leg muscles, but I felt it wasn't enough, so I searched for some exercise videos online, such as squats and wall sits.
During these exercises, my knee doesn't hurt, but afterward, I start to feel pain in the indented area on the outer side of my left knee.
Could you please tell me what might be the issue? I am also considering going to the gym and would like to know what types of exercises are not suitable for someone with knee problems.
Is cycling okay? Additionally, I have previously undergone heat therapy during rehabilitation, and there were times when I felt pain inside my knee.
Why is that? Although the therapist said it might feel hot, what I experienced didn't feel hot at all! A few days ago, I noticed that the skin on both of my knees is darker than the surrounding areas.
Could this be related to my knee issues? Thank you, Doctor, for patiently reading my questions.

1.
It is recommended to assess knee stability before determining the type of exercise.

2.
The skin reaction may be due to the skin being too thin and dry.

Knee pain, especially in the context of inflammation and wear, can be a complex issue that requires careful management and understanding. It’s great that you are actively seeking to improve your knee health through exercises and rehabilitation. However, it’s crucial to approach this with caution, especially given your history of knee issues.

First, let’s address the pain you experience after performing exercises like squats and air chairs. The discomfort you feel on the outer side of your left knee could be indicative of several underlying issues. One possibility is that you may be experiencing patellofemoral pain syndrome, which is common in individuals with knee wear and tear. This condition often arises from improper tracking of the kneecap during movement, leading to pain and discomfort, particularly after activities that involve bending the knee.

Another potential issue could be related to the muscles and tendons surrounding the knee. If the muscles are not adequately balanced or if there is weakness in certain areas, it can lead to increased stress on specific parts of the knee joint, resulting in pain. It’s essential to ensure that your rehabilitation exercises are not only strengthening the quadriceps but also the hamstrings, calves, and hip muscles to provide better support for the knee.

Regarding your question about gym workouts, it’s advisable to avoid high-impact activities that can exacerbate knee pain, such as running or jumping. Instead, low-impact exercises are generally recommended. Cycling is an excellent option as it allows you to strengthen the muscles around the knee without putting excessive stress on the joint. Swimming is another fantastic low-impact exercise that can help improve overall fitness while being gentle on the knees.

You mentioned experiencing pain during heat therapy. While heat can be beneficial for relaxing muscles and improving blood flow, it can also increase inflammation if used improperly. If the heat feels uncomfortable or if you experience pain, it’s essential to communicate this with your therapist. They may need to adjust the temperature or duration of the treatment.

The discoloration of your knee skin compared to the surrounding areas could be related to several factors, including changes in circulation or inflammation. It’s not uncommon for individuals with knee issues to notice changes in skin color due to altered blood flow or swelling. However, if you are concerned about this, it would be wise to consult with a healthcare professional for a thorough evaluation.

In summary, while it’s commendable that you are taking steps to strengthen your knee, it’s crucial to listen to your body and adjust your exercise regimen accordingly. Focus on low-impact activities, ensure a balanced strengthening program, and communicate any discomfort to your healthcare providers. Regular follow-ups with your physical therapist or orthopedic specialist can help monitor your progress and make necessary adjustments to your rehabilitation plan. Remember, the goal is to enhance your knee function while minimizing pain and preventing further injury.
