Surgical Procedure
Pearls & Pitfalls
Video
The second video shows a second look arthroscopy one year after placement of a hemicap. The hemicap is almost completely covered with (fibro-)cartilage
Pearls
To be sure of the angle of the medial malleolar osteotomy, use an arthroscopic probe to identify the ankle joint behind the medial malleolus. (van Bergen, Arch Orthop Trauma Surg. 2011 Jul)
Pitfalls
Make sure not to place the HemiCAP in level of the cartilage or above, to prevent contact pressure on the distal tibia.
