Osteoporosis & bone health

Reduction of subchondral bone marrow lesions concurrent with early recovery of trabecular bone mineral density in knee osteoarthritis following RANKL inhibitor administration for the treatment of osteoporosis: Implying human osteoporotic osteoarthritis?

Semin Arthritis RheumPublished Prospective single-group clinical study

Authors' conclusion

In this clinical study, after the application of a RANKL inhibitor for OP treatment, BMLs and knee pain were effectively reduced in OP patients with symptomatic KOA and BMLs. In addition, the correlation between early recovery of TBMD and reduction in BML area was also demonstrated.
