Osteoarthritis Cartilage . 2013 Nov; 22(2):355-62. PMID: 24185113
Objective: Cartilage injury can lead to post-traumatic osteoarthritis (PTOA). Immediate post-trauma cellular and structural changes are not widely understood. Furthermore, current cellular-resolution cartilage imaging techniques require sectioning of cartilage and/or...
