“…Options have included the use of impaction bone-grafting [22,25,38,40,44], structural bulk allografts [7,11,14,16,17,28,31,39], and tumor-type megaprostheses [2]. Studies with structural allografts and tumor megaprostheses during revision knee arthroplasty have reported encouraging mid-term results, but the high number of complications is a concern.…”

“…Major tibial and femoral bone defects, classified as Anderson Orthopaedic Research Institute (AORI) [10] Types 2B and 3, have been reconstructed using impaction bone grafting with or without mesh augmentation [22,25,38,40,44], structural or bulk allografts [7,11,14,16,17,28,31,39], modular metal augmentations of prostheses [15,32], and tumor-type megaprostheses [2]. Studies using structural allografts have reported numerous complications and minimum 5-year survivorship of 67% to 96% [1,6,7,14,17], whereas reconstructions with tumor-type megaprostheses have shown a 5-year survivorship of 68% [33].…”

Background Multiple studies have reported favorable short-term outcomes using tantalum cones to reconstruct massive bone defects during revision TKA. However, longer-term followup is needed to determine the durability of these reconstructions. Questions/purposes We wished to determine the midterm (1) reoperation rates for septic and aseptic causes, (2) radiologic findings of osseointegration, and (3) clinical outcomes based on the Knee Society score in patients who underwent revision knee arthroplasty with tantalum cones for severe bone loss. Methods We retrospectively evaluated records of 18 patients (18 knees) who underwent revision knee arthroplasty with use of tantalum cones between 2005 and 2008; the primary indications for use of this approach were to reconstruct massive bone defects classified as Anderson Orthopaedic Research Institute Types 2B and 3. During this period, all defects of this type were treated with this approach and no cones were used for more-minor defects. A total of 26 cones (13 tibial and 13 femoral) were implanted. There were 12 female and six male patients with a mean age of 73 years (range, 55-84 years) at the time of revision. The indication for the revision included aseptic loosening (five patients) and second-stage reimplantation for deep infection (13 patients). Patients were followed for a mean of 6 years (range, 5-8 years). No patient was lost to followup. Clinical and radiographic outcomes were assessed with the Knee Society clinical rating system and radiographic evaluation system.

“…5,11,20 In revisions of hinges, the use of highly constrained implants, rotating hinges, fixed-axis hinges, or segmental knee replacements poses the problem that poor bone stock is exposed to increased loading by the highly constrained articulation of the revision implants. 13,15,18,23,26 As a result, implant loosening and bone fracture (Table 1) occur. 1,13,15 Another specific complication is failure of the extensor mechanism.…”

If hinged prostheses are revised with smaller and nonhinged prostheses, do these implants provide adequate fixation, do massive bone grafts in combination with smaller implants reinforce host bone stock, do less constrained prostheses restore ligament tension, and do they avoid problems of the extensor mechanism? To answer these questions, 20 failed hinges were revised to rotating platform revision prostheses with short intramedullary stems in a prospective study. Meticulous soft tissue release techniques and extensive bone grafts were used (tibia, impaction grafting in 16 cases, and structural grafts in four cases; femur, impaction grafting in four cases and structural grafts in 16 cases). The mean followup was 5.3 years (range, 2.3-10.5 years). The Knee Society score improved from a preoperative mean of 21 points (range, 7-49 points) to a mean 81.2 points (range, 59-94 points). One cementless tibial component with extensive impaction grafting became loose. The remaining components (95%) were well-fixed. All cancellous bone grafts showed trabecular remodeling. All structural grafts united to the host bone without resorption. All knees had ligamentous stability after surgery. There were no problems of the extensor mechanism. In this series the rotating platform revision prostheses were used successfully for failed hinged prostheses.
