There were 6 infected nonunions. Ten nonunions were located in the distal femur and the remaining proximal. Case notes and radiograph review were used to determine fracture union, lengthening achieved, and complications. Patient outcome was assessed using the SF-12, Tegner\u2013Lysholm Knee Score, and Oxford Hip Score.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results:<\/jats:title>\n            <jats:p>Fracture union was achieved in all patients. The mean lengthening performed was 51\u200amm (range 30\u201380) with a fixator time averaging 39 weeks (range 17\u201380). The bone healing index was 1.9\u200amonths\/cm. All but 2 patients were restored to within 5\u200amm of opposite leg length; 1 patient subsequently underwent contralateral limb shortening. The SF-12 had a mean Physical Health Composite Score of 40.0 (22.4\u201352.9) and a mean Mental Health Composite Score of 49 (30.7\u201362.0). The Oxford Hip Score was scored at a mean of 39 (21\u201347) and the Tegner\u2013Lysholm score had a mean of 71 (36\u201394). There were 3 cases of fracture\/deformity from the lengthened bone column (regenerate) and 2 patients required a quadricepsplasty for knee stiffness that was present prior to the treatment for the nonunion.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion:<\/jats:title>\n            <jats:p>Bifocal treatment of complex periarticular femoral nonunions offers a single solution for dealing with bone loss, nonunion, and instability.
