Rupture of the anterior cruciate ligament is one of the most common causes of lameness, pain, and consequent degenerative knee changes in dogs. Its rupture leads to significant instability of the knee, which is manifested by cranial tibial thrust, subluxation, and excessive internal rotation of the lower leg. It occurs in acute and chronic form, and the most successful method of treatment is surgery. Osteotomy techniques are the most commonly used methods, of which tibial plateau leveling osteotomy (TPLO) is the most popular. Other techniques are cranial closing wedge osteotomy, modified Maquet procedure, tibial tuberosity advancement, triple tibial osteotomy, and tibial wedge osteotomy. Each of the mentioned techniques adequately solves the problem of rupture of the anterior cruciate ligament. When selecting, the body weight of the dog, the conformation of the knee joint, the state of the ligaments in the knee, the lifestyle and the level of activity of the dog play a big role. Each of the mentioned techniques has its advantages and consequent complications. In general, the most common complications are suture dehiscence and infection, and the most severe include a late-onset meniscus tear, and a femur, tibia, or fibula fracture. All techniques are similarly successful, but TPLO shows the best long-term results. With it, dogs have the greatest chance of achieving a high quality of life, minimal knee pain and restored normal and total knee function. According to some studies, CBLO shows better results than the gold standard, TPLO, but it is a newer technique, so surgeons do not use it as often.
