Transcriptional profiling of articular cartilage in a porcine model of early post-traumatic osteoarthritis

36 Yucatan minipigs underwent anterior cruciate ligament (ACL) transection and were randomly assigned in equal numbers to no further treatment, reconstruction or ligament repair. Cartilage was harvested at 1 and 4 weeks post-operatively and histology and RNA-sequencing performed. The generated data served to identify the molecular pathophysiology present in early post-traumatic osteoarthritis (PTOA), as well as differences between surgical treatments.
