Our 26 year old daughter (dance instructor) has complained of a deep inside pain in her knee. There is no known trauma to the knee. She recently had an MRI and today was told that she needs to be seen again due to a mass being seen on the MRI. Any ideas of what the mass could be?
Hello, It would have been of great help if you had mentioned the MRI reports. The mass in the posterior aspects of the knee can be either due to the ligament sprain within the knee joint leading to a formation of cysts called as bakers cyst in the popliteal fossa.  This mass is basically a protective mechanism of the body to give rise to additional tissue to avoid any major knee injuries to occur. With the proper exercise of the muscles of the lower limb will help to avoid the additional pressure over the knee ligaments and the mass formation will subside. Most of them are advised surgery but actually, none need a get operated as this will go off on its own without giving any kind of trouble. In my clinical practice of over 12 years. This is one of the common thing heard and none have been needed surgery. Just exercise and regaining strength in the lower limb muscles have shown outstanding results. Hope I have answered your query. Let me know if I can assist you further. Jay In Chat Doctor.
