Arthroscopy, and subsequent arthrotomy, showed complete tearing of the CCL and an intact but grossly thickened LDE. No evidence of avulsion or bony proliferation associated with the LDE was appreciated. Tibial plateau leveling osteotomy (TPLO) and tenectomy of the LDE returned the dog to normal weight‐bearing. No evidence of ectopic mineralization in the affected limb or similar clinical signs in the contralateral limb have been observed in 12 months follow‐up.</p> </sec> <sec id="vsu12153-sec-0006" sec-type="section"> <title>Conclusions</title> <p>LDE tenectomy followed by stabilization of the stifle by TPLO resulted in a functional outcome. Mineralization without concurrent avulsion of the LDE has not been reported in dogs; however, posterolateral tendon injury in people has been linked to knee instability and cruciate ligament rupture.</p> </sec> </abstract>
