Background Addressing bone loss in revision TKA is challenging despite the array of options to reconstruct deficient bone. Biologic reconstruction using morselized loosely-packed graft potentially allows for augmentation residual stock while offering physiologic load transfer. However it unclear whether reconstructions are durable. Questions/purposes We therefore sought determine (1) survivorship and complications, (2) function, (3) radiographic findings cementless combination with osseous defects at TKA. Patients Methods retrospectively reviewed 56 patients who had undergone TKAs long-stemmed components loose our institution. There were 26 men 30 women a mean age 68.3 years (range, 56-89 years). followed assess symptoms function detect loosening, component migration, incorporation. The minimum followup was 4 (mean, 7.3 years; range, 4-10 Results Cumulative prosthesis survival, as an end point, 98% 10 years. Oxford Knee Scores improved from 21 (36%) preoperatively 41 (68%) final followup. Five (9%) reoperations complications. Conclusions Our observations suggest this technique reproducible obviates need excessive resection, use large metal augments, mass allografts, or custom prostheses. It be reconstructed reliably durable midterm fixation. Level Evidence IV, therapeutic study. See Guidelines Authors complete description levels evidence.
