1. Complete exposure of the knee joint is facilitated by the reflection of the tibial tubercle and of the patellar tendon. Early function is instituted, following re-attachment of the tubercle by means of a metal nail.
2. The anterior inclination of the superior articular surface of the tibia must be corrected to relieve the deformity of genu recurvatum and to give adequate knee function.
3. In reconstructive surgical procedures, metal blocks may be used advantageously to fill bone defects.
