-Tibia Plateau Leveling Operation-TPLO
Licensed by Slocum Enterprises –Eugene, OR
-First “Break-Through” for RCCL Repair, esp. Active and Obese Patients
-Corrects the sloping posterior tibia
-Allows for the Correction of Vargus/Valgus in one operation
-Most Invasive and Traumatic of current procedures
-Most likely to require Rehabilitation
-Increases Pressure in the Posterior joint space and on the menisci
-Can be used when other procedures have been performed
-Implants made of SS, are quite massive, limited industry
standards

Tibial Tuberosity Advancement
Developed by Slobodan Tepic and Pierre Montavon

TTA
Restores stability by adjusting joint force vectors
Maintains congruency of joint
Allows unimpeded full range of motion
Preserves primary loading axis of tibia
Increases lever arm of quadriceps force and thus
reduces all internal joint reactions
 Implants are made specifically for TTA and are
Titanium for reduced body reactivity
 Implants and instruments made in Switzerland and
Germany and of highest quality and standards

Requires a bone graft
Less Allowance for Technical Errors
More difficult to correct Valgus/Vargus
Potential for Non-Union is greater
Patients will weight-bear immediately upon
recovery from anesthesia which lessens
requirement for rehab
Unkown if Osteoarthritis is reduced but is
expected to do so with current case experience
Over 40,000 cases world-wide have been
performed

Both require strict aseptic techniques
Both require extensive inventory of
implants
Both require Orthopedic Power Equipment
Both require extensive array of Orthopedic
