Knee problems
About two weeks ago, I jumped up three steps at once, and I did it with somewhat poor form (pushing off strongly with my left foot).
At the moment of the jump, I felt like all my force was concentrated on my knee.
After jumping, I experienced a sensation similar to jumping from a higher place without cushioning, which caused my knee to hurt.
Since then, while walking, I sometimes feel that my left knee is a bit unstable, accompanied by a faint popping sound (usually when I turn to the right), but it doesn't persist.
I don't feel any pain when exercising or weight training.
Could you please tell me what might be the issue, doctor? Thank you!

Hello Mr.
Chen: You may want to consult an orthopedic specialist to check if there is any damage to the articular cartilage or other issues.
If obvious problems with the bones, joints, or ligaments are ruled out and you still experience discomfort, it may fall under the category of "bone misalignment." You can seek assistance from a traditional Chinese medicine practitioner who specializes in injuries to help with adjustments, along with appropriate rest, which should help improve your symptoms.
I hope this answers your question.

More Info
Knee pain after jumping, especially following an incident where improper technique may have been used, can be indicative of several potential issues. Given your description of the event—jumping up three stairs with a focus on your left leg—it's possible that you may have strained or injured structures within the knee joint. Here’s a breakdown of what might be happening and some recommendations for addressing your concerns.
Potential Issues
1. Patellar Tendonitis: This condition, often referred to as "jumper's knee," occurs when the patellar tendon, which connects the kneecap (patella) to the shinbone (tibia), becomes inflamed. This can happen due to repetitive stress or a sudden increase in activity, such as jumping.
2. Meniscus Injury: The meniscus is a C-shaped cartilage that acts as a cushion between your thigh bone (femur) and shinbone (tibia). A sudden twist or turn during a jump can lead to a meniscus tear, which might explain the feeling of instability and the noise you hear when turning.
3. Ligament Strain: The knee is stabilized by several ligaments, including the anterior cruciate ligament (ACL) and the medial collateral ligament (MCL). A sudden movement or awkward landing can strain these ligaments, leading to pain and a feeling of instability.
4. Patellofemoral Pain Syndrome: This condition is characterized by pain around the kneecap and can be exacerbated by activities that put stress on the knee joint, such as jumping or squatting. It may also cause a popping or grinding sensation.
Recommendations
1. Rest and Ice: Initially, it’s crucial to rest the knee and apply ice to reduce any swelling. Avoid activities that exacerbate the pain, particularly jumping or heavy lifting.
2. Physical Therapy: Engaging in physical therapy can be beneficial. A physical therapist can guide you through exercises that strengthen the muscles around the knee, improve flexibility, and enhance stability. Focus on quadriceps and hamstring strengthening, as well as balance exercises.
3. Knee Brace: If you feel instability, using a knee brace during activities may provide additional support and confidence while you heal.
4. Gradual Return to Activity: Once the pain subsides, gradually reintroduce activities. Start with low-impact exercises, such as swimming or cycling, before progressing to jumping or running.
5. Consult a Specialist: If the pain persists or worsens, it’s advisable to consult an orthopedic specialist. They may recommend imaging studies, such as an MRI, to assess for any tears or injuries to the ligaments or meniscus.
6. Modify Activities: Pay attention to your jumping technique. Ensure that you land softly and with your knees aligned over your toes to minimize stress on the knee joint.
Conclusion
While it’s encouraging that you do not experience pain during weight training or other exercises, the symptoms you describe warrant attention. The knee's complexity means that even minor injuries can lead to discomfort or instability. By taking proactive steps—resting, seeking physical therapy, and possibly consulting a specialist—you can address the underlying issues and work towards a full recovery. Remember, listening to your body and allowing adequate time for healing is crucial to prevent further injury.
