Radiographs and magnetic resonance imaging of right ankle in the illustrated case. Anterolateral (A) and lateral (B) views showing a cluster of ossifications at the posterolateral ankle. Coronal (C) and transverse (D) views showing that the bursal sac is adherent to the peroneal tendon sheath and the skin.

3. Fig 2
Endoscopic resection of bursal chondromatosis of right lateral ankle. The patient is in the lateral position. The bursa and the peroneal tendon sheath are outlined. The proximal viewing portal (pp) and the distal viewing portal (dp) are marked proximal and distal to the bursa and along the peroneal tendon sheath.

Endoscopic resection of bursal chondromatosis of right lateral ankle. The patient is in the lateral position. (A) The proximal portal is the viewing portal. Synovectomy is performed with an arthroscopic shaver through the bursal portal. (B) Endoscopic view showing resection of the inflamed synovium (IS) with preservation of the integrity of the bursal sac (BS).

Endoscopic resection of bursal chondromatosis of right lateral ankle. The patient is in the lateral position. (A) Endoscopic view showing resection of the bursal sac (bs) by an arthroscopic shaver. (B) Endoscopic view showing internal drainage of the bursal sac to the peroneal tendon sheath by resection of part of the peroneal tendon sheath. The peroneus brevis (pb) and peroneus longus (pl) tendons are exposed.
