TL;DR: Indications for mosaicplasty with a plug transfer from the knee to the talus must be considered carefully, as at midterm, moderate outcome and considerable donor-site morbidity may be found.

TL;DR: The data support realignment surgery for patients with asymmetric ankle osteoarthritis, and outcome correlated with achieved reversal of tibiotalar tilt and the score of Takakura et al.

TL;DR: The modified AMIC procedure is safe for the treatment of OCLs in the ankle with overall good clinical and MRI results and normal signal intensity of the repair tissue compared with the adjacent native cartilage was seen.

TL;DR: SPECT-CT had significantly higher interobserver agreement, especially when evaluating the naviculocuneiform and tarsometatarsal joints, which is useful in localising active arthritis especially in areas where the number and configuration of joints are complex.

TL;DR: Retinacular lengthening showed less medial instability, less quadriceps atrophy, and a better clinical outcome at 2 years compared with retinacular release, and it is believed that this may be explained by the controlled preservation of the lateral patellar muscle-capsuloligamentous continuity after retinocular lengthening.
