Stifle Retractor. The examination of the meniscus and intra-articular structure during anterior cruciate repair is a real necessity. This visualisation is often difficult even in the largest of dogs. The stifle retractor allows gentle retraction between the femur and tibia, exposing the entire stifle joint to a thorough exam without damaging the joint surface. Stainless steel. Improved model has longer jaw tips which are self protecting when the instrument is in the closed position. Once inserted atraumatically into the stifle, distraction exposes the longer tips for maximum grip. The best instrument to examine the caudal horn of the medial meniscus.
