2 days duration, H/o injury so it may be Post traumatic inflammation, R/o fracture/ligament or meniscal injury. Then think of arthritis, ARF... Investigation, Rx as advised by @Dr. Animesh Majhi

Basically we r having arthritis of right knee. 1. Rule out rheumatic especially if it's tender. Watch for migratory nature and response to ASPIRIN Other dds JIA - but the duration s too less (need at least 6 weeks to diagnose) Septic - but there s no fever.

Most common d/d of an acute onset large joint swelling in a young male is reactive arthritis , septic arthritis or undifferentiated spondyloarthritis. Unfortunately history again becomes a major differentiator rather than investigations.

can be traumatic synovitis, reactive arthritis or rheumatic. investigate as suggested by Dr animesh majhi

Injury Knee joint, one has to treat the injury with Analgesics, work up with X-RAY. R/O FRACTURE. D/D : SEPTIC ARTHRITIS. RX : ACORDINGLY.

I shall also like to exclude hemarthrosis, may be secondary to hemophilia.

I agree with Dr.R Khan.

Injury mark is there so, it may be traumatic effusion or sub acute septic arthritis????
