ABSTRACT
OBJECTIVE:
To describe the technique of combined center of rotation of angulation (CORA)-based leveling osteotomy (CBLO) with tibial tuberosity transposition (TTT) and to compare the load to failure between CBLO combined with TTT and CBLO or TTT alone. STUDYDESIGN:
Ex vivo study. SAMPLE POPULATION Twelve pairs of cadaveric pelvic limbs.METHODS:
Six pairs of cadaveric tibia were tested in each group (CBLO-TTT versus CBLO) and (CBLO-TTT versus TTT) with each limb randomly assigned to a treatment group. Construct stability was determined by applying a tensile force to each patellar tendon until failure occurred. Load at failure and mode of failure were recorded for each specimen.RESULTS:
No difference in mean load to failure was identified between CBLO-TTT (897 N) and CBLO alone (943 N) (P = .81). There was also no difference in the mean load to failure between the CBLO-TTT (928 N) and TTT alone (1046 N) (P = .12).CONCLUSION:
Performing a TTT in combination with a CBLO does not weaken the construct failure to load when compared with each procedure performed alone. CLINICALSIGNIFICANCE:
A combined CBLO and TTT could be considered a viable option for concurrent management of a cranial cruciate ligament deficient stifle and medial patella luxation.
