Macroscopic evaluation of tissue from primary and revision TKA.
Synovial membrane (upper panel) and infrapatellar fat pad (lower panel) were isolated from patients undergoing primary TKA (left panel), patients undergoing non-arthrofibrotic revision TKA (middle panel) and patients undergoing arthrofibrotic revision TKA (right panel). Both tissues from primary TKA patients appeared to be homogenous, fatty, non-fibrotic tissue. In contrast, tissue from revision TKA patients appeared to be dense, pigmented, fibrotic tissue regardless of clinical diagnosis. Images acquired by Dr Lee Borthwick.
