Hello
Your MRI shows two main issues: a small osteochondral lesion (cartilage + underlying bone damage) on the lateral femoral condyle, and a mild (grade 2) meniscus tear. Since there is no bone marrow edema and the lesion is relatively small (9×4 mm), this is not an aggressive or advanced stage, but it can still cause persistent pain.
Treatment usually starts conservatively. This includes activity modification (avoiding deep squatting, running, stairs overload), structured physiotherapy to strengthen the quadriceps and stabilize the knee, weight management if needed, and medications for pain relief. In some cases, injections like PRP or hyaluronic acid are used to reduce symptoms and support joint health.
If pain continues despite proper rehab, surgical options are considered. For the osteochondral lesion, procedures like arthroscopic drilling or microfracture are done to stimulate healing of the cartilage. For the meniscus, since it is a small grade 2 tear, it usually does not require surgery unless it progresses or causes locking/catching; if needed, arthroscopic repair or trimming is done.
The bony fragment noted near the lesion may represent a loose or partially detached piece, which becomes important if it causes mechanical symptoms—in such cases, arthroscopy is more strongly recommended. The fabella is a normal anatomical variant and usually does not need treatment unless symptomatic.
Overall, if your pain is manageable, a non-surgical approach is reasonable first. If symptoms persist or worsen, arthroscopic treatment (as previously advised) becomes the next step, with generally good outcomes for lesions of this size.
Take care
When dealing with an osteochondral lesion in the knee, like yours on the lateral femoral condyle, alongside a meniscus tear, it’s crucial to weigh a number of treatment paths. Since your osteochondral lesion isn’t accompanied by bone marrow edema currently, that could mean it’s relatively stable, but it’s still a potential source of your pain and needs attention. The small tear of the medial meniscus can also contribute to discomfort and instability. For an osteochondral lesion, especially if you’re experiencing pain, surgical options, including the arthroscopy and drilling you’ve mentioned, might be beneficial. Such procedures can aid in promoting new bone growth and improving the condition of the cartilage. PRP injections can assist healing by promoting tissue regeneration but should be discussed in detail with an orthopedic specialist to determine if it’s a good fit. As for the meniscus tear, physical therapy is often quite effective in alleviating symptoms, focusing on strengthening the surrounding muscles to support the knee joint better. In some cases, if the tear is large or symptomatic, an arthroscopic repair might be considered. It’s important to incorporate a rehabilitative program into your routine, addressing strengthening, flexibility, and range of motion, potentially under a physiotherapist’s guidance. This approach not only helps to reduce pain but can improve knee function. It’s crucial to consult with an orthopedic specialist to closely monitor these conditions and determine the best individualized treatment plan. Considering you’re experiencing localized pain, make sure not to delay in seeking further consultation. Prompt management is key to preventing further deterioration and maintaining knee health.
