Tuberculous synovitis - knee

Case contributed by Dr Maulik S Patel


Left knee - non traumatic pain, swelilng, restricted movements for about 5 mths. Difficulty in walking - 2 wks.

Patient Data

Age: about 35 yrs
Gender: Male

Periarticular osteopenia. Supra and infrapatellar soft tissue density.


Diffuse synovial thickening with hypervascularity was seen involving suprapatellar, infrapatellar, medial - lateral joint recesses and also in posterior joint space.

Collection / granulation was noted extending cranial to suprapatellar pouch, into muscle.

Lymphnodes  are noted in left iliac - inguinal - popliteal regions.

Case Discussion

Knee arthroscopy was done. Defect was seen in suprapatellar capsule which explains collection out side joint capsular in distal thigh.

Synovitis is a non-specific finding. However, extra-articular collection and lymphnodenopathy favor infective etiology rather than inflammatory like rheumatoid.

Histopathology - Tuberculosis.
