Hi, thanks for writing to HCM.
After going through the description , I suspect MENISCAL TEAR in your knee joint.
This can be ruled out only by an MRI
scan of knee joint.
Not all meniscal tears needs surgical managment.
The initial management is as follows -
* activity modification by avoiding impact sports which causes more strain on the knee joint
* using an elastic compression bandage to reduce the swelling
* Ice packing to alleviate the pain
to strengthen the quadriceps muscle
If the above measures fail to provide you pain relief, get MRI done and consult an orthopedic surgeon for further management.
Hope this information is helpful. Good day
