Anatomical reconstruction techniques that can restore normal joint kinematics without increasing surgical complications could potentially improve clinical outcomes and help manage anterior cruciate ligament injuries more efficiently. ⋯ Single-tunnel double-bundle anterior cruciate ligament reconstruction with anatomical placement of hamstring tendon graft could provide improved clinical outcomes over a conventional single-bundle reconstruction.

High tibial osteotomy is technically demanding. Risks include injury to the popliteal neurovascular bundle. The present goal was to further define this risk. ⋯ To perform a safe osteotomy, the knee should be positioned in 90 degrees of flexion with the saw angled less than 30 degrees from the coronal plane. A protective device deep to the popliteus may protect against popliteal injury.

Increase in expression of substance P (SP) and calcitonin gene-related peptide (CGRP) has been reported in clinical samples of tendinopathy. ⋯ There was increased expression of SP and CGRP after collagenase-induced tendon injury, and their expression was positively associated with double-stance duration. Clinical Relevance Substance P and CGRP might be involved in the pathogenesis and origin of pain of tendinopathy and could be the targets for future intervention.
