Hi,
Dear,thanks for the query to HCM.
After going through the query in details,In my opinion-
-Your lump on the knee left-is
Synovitis with Effusion with knee arthritis?early-OA.
-Cause- is the aging OA due to overuse of the joint and disuse
atrophy of the quadriceps by sedentary job life style.
Synovitis of the knee joint with overgrowth of the synovial granular tissue erodes the knee joint surfaces and OA occurs with reactionary fluid in the knee joint as in your case.
-Your symptoms suggest progression to the back of the left knee from the front knee area.
-Treatment- I would advise you to see Orho-Surgeon / Physician who would treat it after proper investigation.
Hope this would help you to plan treats with your doctor.
Wishing you fast recovery and Healthy life.
Wellcome to HCM for further query to My HCM clinic.
Have a Gd day.
