Case contributed by Dr Maulik S Patel

Presentation

Atraumatic origin of the left knee pain on the medial side for the last month. Increased pain for the last few days.

Patient Data

Age: 50 years
Gender: Female

There is a well-defined calcification (17 x 16 x 9 mm) involving the proximal end of the medial collateral ligament of the knee. It correlates with the site of pain. The rest of the ligament shows normal echopattern. The ligament is intact. The underlying femoral condylar cortex is intact. There was no suprapatellar recess effusion.

Arthroscopic images show a release of calcium from the medial collateral ligament. Anterior cruciate ligament and menisci are normal.

Case Discussion

A female presented with the atraumatic origin of medial side knee pain for the last month.  Due to increased local pain during the last few days, a local steroid injection was given in another hospital which failed to reveal pain. Ultrasound shows calcification of the medial collateral ligament of the knee at its proximal end.

Arthroscopic removal of the calcium was done. Arthroscopic photos courtesy: Operating surgeon Dr. Ritesh Patel.
