Rehabilitation Following Meniscus Repair
Phase 1: Postop phase Goals • Protect healing of repair • Decrease pain • Manage effusion • Increase weight-bearing tolerance per procedure • Gradually improve knee ROM to 0–90° by week 2 and 0–120° by…
Meniscal Posterior Root Tear
Fig. 8.1 This coronal image shows an extruded medial meniscus On the sagittal MRI images, root injury will manifest with anterior displacement of the meniscus. As the meniscus breaks free…

Biological Augmentation of Meniscus Repair and Restoration
Fig. 11.1 Arthroscopic image demonstrating near full-thickness cartilage loss on the lateral femoral condyle in the knee of a patient with lateral meniscus deficiency. In many cases, meniscus damage is…
Basic Science of Meniscus Repair: Limitations and Emerging Strategies
Fig. 10.1 Schematic of a horizontal meniscal tear highlighting the limitations to repair (hypovascularity, hypocellularity, and inflammation) and pro-repair strategies, including enhancing vascularity (angiogenesis, fibrin clot, vascularized graft or conduit),…
Meniscal Scaffolds: Options Post Meniscectomy

Physical Examination for Meniscus Tears
Fig. 2.1 Palpation of the meniscus. (a) Palpation of medial meniscus. (b) Palpation of lateral meniscus The lateral knee must also be evaluated carefully with palpation. Analogous to the medial…
