TOTAL KNEE REPLACEMENT FOR METASTATIC DESTRUCTION OF THE PROXIMAL TIBIA

Discussion. Accurate reduction of a long bone fracture is important, since it has been shown that degenerative changes can follow even minimal mala1inment (Kettel-kamp et al 1988). The maximum acceptable angular deformity in the tibia or femur has not been accurately determined (Ting et al 1987), but 1 5#{176}of femoral and 5#{176}of tibial angulation have been accepted (Mooney and Claudi 1984). Values greater than this may lead to deterioration of the articular surfaces. The method described here is simple, reproducible, does not affect the surgical field, is more accurate than conventional plain radiography, involves less radiation to the patient and theatre staff and saves theatre time.
