Keppler L, Klingbeil S, Navarre F, et al. - This study was undertaken to investigate if the lateral approach is superior to a modified medial approach in terms of implantation accuracy and subjective outcome. Researchers conducted a retrospective study including a total of 175 patients with lateral unicompartmental knee arthroplasty (UKA) between 2015 and 2020. They used the lateral approach in 82 patients, and the medial approach in 93 patients. Different imaging criteria on postoperative radiographs were examined to evaluate implantation accuracy. They assessed postoperative patient-related outcome measurements (PROMs) (OKS, LEFS, and EQ5D). It was shown that the lateral procedure is not superior regarding different radiological accuracy criteria. The findings suggested that Hoffa´s fat pad–preserving medial approach exhibited good outcomes in implantation accuracy and thus is a good alternative to implant lateral UKA. In addition, significant improvement in PROMs could be demonstrated.
