Abstract：Objective To explore the outcomes of high tibia osteotomy with bone grafting and internal fixation + arthroscopic reconstruction of anterior cruciate ligament ( ACL ) in the treatment of ACL injury combined with varus osteoarthritis of the knee. Methods 14 patients with varus osteoarthritis of the knee and ACL injury underwent arthroscopic debridement, with intra-articular lesions cleaned. Autologous gracilis muscle and semitendinosus muscle tendons were taken and underwent weaving treatment. After that, an ACL sighting device was used to create a bone tunnel in the medial cortex near the tibial tubercle ( under and no less than 1cm from the osteotomy line ). The ACL was reconstructed by the conventional method. The femoral ifxation was performed with the button titanium plate and the tibial ifxation with the absorbable screw. At the same time, osteotomy was performed on the upper edge of the tibial tubercle, pointing to the top of the proximal tibioifbular joint, and the sagittal plane was parallel to the articular surface. The lateral bone cortex was not completely cut off, and high tibia osteotomy was performed. When the allogeneic bone was iflled in, the proximal tibial ifxation was performed with the anatomical titanium locking plate and genu varum was corrected. Results All patients were followed up for 6-28 months. Healing of the osteotomy ends was achieved in patients within 3 months after the surgery, with signiifcantly relieved joint pain, satisfactory range of movement ( ROM ) and no symptom of joint instability. The HSS scores were ( 50.25±4.82 ) points preoperatively and ( 80.12±3.41 ) points postoperatively; The Lysholm scores were ( 47.07±5.25 ) points preoperatively and ( 78.08±2.52 ) points postoperatively, and the differences were statistically signiifcant ( P<0.05 ). Conclusions It is an effective and minimally invasive method of high tibia osteotomy with bone grafting and internal ifxation+arthroscopic reconstruction of ACL in the treatment of varus osteoarthritis of the knee combined with ACL injury.
