Fig 3.

This is a needle arthroscopic view of a right ankle. Two images are included in this figure. The left figure shows a clear (osteo)chondral defect, which is identified and thereafter graded as an International Cartilage Repair Society (ICRS) grade 2. The (osteo)chondral lesion is locate on the lateral talar dome (centroposteriorly). In the right image one can see the hypertrophic anterior inferior talofibular ligament (AITFL) which is also observed on the left image. The hypertrophic ligament causes impingement on the anterolateral ankle joint, and was resected with a 3.0 mm shaver. Moreover, debris and synovial hyperplasia can be resected with the 3.0 mm shaver.
