Abstract

A 7-month-old, 5.2 kg spayed female Norwegian Forest cat was referred for chronic, non-weight-bearing lameness in the left pelvic limb that has been present since 3 months old and has not responded to medical conservative therapy. Based on orthopedic and radiographic examination, concomitant cranial cruciate ligament rupture (CCLR) and medial patellar luxation (MPL) of the left hind limb were diagnosed. In this case, cranial tibial wedge osteotomy (CTWO) was adopted to overcome side effect of performing other osteotomy techniques such as impairing the growth plates in the proximal tibia. Additionally, patient-specific surgical guides were applied to improve surgical accuracy. The patient showed an improvement in weight-bearing scores and gait condition during follow-up periods without complications. In our case, CTWO combined with corrective surgery for MPL can be used to treat concomitant CCLR and MPL without damaged on the growth plates and shows good clinical outcomes in an immature cat. Furthermore, the use of a surgical guide facilitates surgical procedures that minimize surgical error and increase surgical precision. This case study suggests that CTWO assisted by patient-specific surgical guides may be a viable surgical option for treating an immature cat with concomitant CCLR and MPL.
