PRIOR ACLR RELATED TO KNEE OSTEOARTHRITIS (Orthopedics This Week)
If you are a young athlete who had anterior cruciate ligament reconstruction (ACLR) you have a 33% chance of getting osteoarthritis of the knee within a year. That is the result of a study conducted by Adam Culvenor of the University of Queensland School of Health and Rehabilitation Sciences in Brisbane, Australia. The study was published in Arthritis & Rheumatology.
According to MedPage Today, which reported on the study, 21 patients or 19% of 111 participants who had undergone ACLR a year earlier met the MRI criteria for tibiofemoral OA. Another 19 patients or 17% met the MRI criteria for patellofemoral OA. Put together, this means that 31% of the participants had MRI-defined knee OA one year after undergoing an ACLR. Among the uninjured controls, not one participant had MRI-defined patellofemoral or tibiofemoral OA.
Doctors detected bone marrow lesions (BMLs) in the femoral trochlea region in 19% of participants; they found cartilage lesions in 31% of participants and osteophytes in 37% of participants. Pathology in the patellofemoral joint on MRI included not only early features of OA such as BMLs and partial...
