Mobile-bearing, congruent patellofemoral prosthesis: short-term results.

Purpose: To report the short-term outcome of the low contact stress (LCS) patellofemoral prosthesis in 51 knees.

Methods: 12 men and 37 women aged 23 to 79 (mean, 53.4) years underwent 51 consecutive LCS patellofemoral replacements.

Acute compression and lengthening by the Ilizarov technique for infected nonunion of the tibia with large bone defects.

Purpose: To assess the Ilizarov technique in treating large infected tibial defects by resection of the infected focus, its acute compression, and gradual distant site lengthening.

Methods: 27 men (mean age, 39 years) with infected nonunion and large bone defects of the tibia underwent complete resection of the nonunion site, debridement, sequestrectomy, lavage, and Ilizarov ring fixator application. Patients underwent acute compression of the defect site, followed by distant site metaphyseal corticotomy for simultaneous lengthening.
