Reduction of the articular block
The chosen approach must adequately expose the articular surface of the
distal femoral condyle. Reduction aids that are helpful include:
- A 5.0 mm or 6.0 mm Schanz pin in the medial and/or lateral femoral condyle
to act as a joystick.
- Pointed reduction forceps, or large pelvic reduction clamps, to clamp from
medial to lateral across the intercondylar split.
Pearl: combination of reduction aids
Attempts at reduction of the intercondylar split with the pointed reduction
forceps alone are often unsuccessful, as rotational control of the femoral
condyle is also needed. The use of the Schanz pin in conjunction with the
pointed reduction forceps is therefore preferred.
