My concern

It’s frustrating when knee pain doesn’t seem to improve, especially if it’s impacting your daily activities. The lingering pain after a twisted knee could indeed suggest a range of issues—from tendinitis, as your doctor mentioned, to something more structural. When sharp pain occurs during squats or stairs, it might indicate something like a meniscus injury or ligament strain, which doesn’t always resolve as easily as a sprain. It’s fair to question whether an MRI is appropriate; this imaging can help visualize soft tissue injuries more clearly. Persistent pain after several weeks, especially with your activity limitations, warrants further evaluation. You might consider seeking a second opinion from an orthopedic specialist or a sports medicine physician. They can assess your knee’s stability, check for signs of other injuries, and determine if imaging is truly needed. Meanwhile, ensure you’re managing the pain with adequate rest, appropriate exercises focusing on strengthening around the knee (as advised), and possibly anti-inflammatory medications if suitable for you. Be mindful of pushing into activities that exacerbate your pain. If symptoms significantly worsen or if new symptoms arise, like significant swelling, locking, or giving way of the knee, you should reach out to a healthcare provider without delay. It’s crucial, though, to keep your health care providers informed about the persistence and specifics of your pain, as this is key in determining the next best steps for your treatment.
