Surgeries

Question 1

What is Abrasion Trochleoplasty? + instruments needed

Answer 1

This involves the removal of the articular cartilage and subchondral bone from the trochlea sulcus. It is less technically demanding than other surgical repair options. Instrumentation requireed: Gelpies, Rongeurs/or Bone Rasp.

Question 2

What is Trochlear Wedge Sulcoplasty/ Recession? + instruments needed

Answer 2

This involves the removal of a ‘V shaped’ wedge of bone and cartilage from the femoral trochlear sulcus, followed by replacement of the original wedge in a recessed position. This surgical approach is more technically demanding. Instrumentation required: Fine toothed hand saw blade, Rongeurs and the Gelpies.

Question 3

What is Trochlear Block Sulcoplasty/ Recession? + instruments needed

Answer 3

This involves the removal of a block from the femoral trochlea sulcus. This surgical approach provides a bigger proximal recession, which may provide more stability for the patient. It is a technically demanding surgery. Instrumentation required: Fine tooth hand-saw blade, modular osteotome, Mallet, Rongeurs, and the Gelpies.

Question 4

What is Tibial Tuberosity Transposition? + Instruments needed

Answer 4

This surgical approach is used to improve alignment of the patellar mechanisms for patients who have an abaxially displaced tibial tuberosity. This involves cutting the tibial tuberosity and transpositioning laterally to achieve neutral orientation of the patella ligament. Instrumentation required: gelpies, mallet, rongeurs, Bone Rasp, IM Pins (K wire), Jacobs chuck handle and key, sagittal saw, listen bone cutters, modular osteotome, cerclage wire, wire twisters (possibly lag screw).
