In patients with frozen shoulder, interscalene block and continuous patient-controlled analgesia via an interscalene catheter provided sufficient analgesia and contributed to the recovery of shoulder functions through an effective and safe exercise program, with no side effects or complications. However, further studies are needed to assess the feasibility of home applications of interscalene patient-controlled analgesia to increase cost-effectiveness and patient satisfaction.
The use of the EHL tendon as a reference improves coronal tibial alignment. The EHL is a reliable anatomical landmark to use with extramedullary guide systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
