Hi,Dear,Thanks for your query to HCM.
Dear I read your query and reviewed it with context to your query facts.
Based on the facts of your query, you seem to suffer from-
Synovial Thickening with
Arthritis / and or /from Oschgood Shlatters disease of the knee from the
injury to tendon few years ago.
Surgery may be required only if -Arthritis with Synovial thickening is there.
For Oschgood Shlatter's disease -
Cold Compresses+Tab
Motrin would relieve it in initial acute period and would not need any treatment as the lump would reslove over a time,as the time passes by.
USG / X-ray Knee would fix the diagnosis prior to surgery and consultation from Ortho-Surgeon.
Second Opinion from Ortho-Surgeon would be needed to rule out other causes of such a lump prior to treatment.
Hope this reply would help you to plan further treatment with your family and specialist doctors there.
Welcome for any further query in this regard.
Good Day!!
