Hi, It is prudent to make sure the stifle is xrayed when ACL problems are suspected. A friend's Rottie was operated on for ACL and was slow to heal, she took her to a specialist where the originating problem was diagnosed. She had osteosarcoma. The original vet had not xrayed prior to surgery which would have highlighted the malignancy. Unfortunately some ACL weaknesses occur due to bone cancers.
