|
| Nelson et al. [64] | 2003 | 20 | 70 | N/A | Porous tantalum (PT) patellar components | 23 | Good or excellent results in 17 patients; 3 polar patellar fractures postoperatively; no sign of loosening |
|
| Nasser and Poggie [65] | 2004 | 11 | 66 | N/A | Porous tantalum (PT) patellar components | 32 | All implants stable, high patients’ satisfaction |
|
| Meneghini et al. [57] | 2008 | 15 | 68.1 | Types 2 and 3 | Femoral and tibial tantalum cones | 34 | All cones were osteointegrated at the follow-up; no loosening or migration |
|
| Long and Scuderi [58] | 2009 | 16 (all tibial) | 66.1 | 2 T2A, 3 T2B, 4 T3A, 7 T3B tibial bone defects | Tantalum tibial cones | 31 | 2 cases of reinfections; in the remaining cases no reoperations and no signs of loosening; good short-term results were achieved in complex revisions, with these new cones |
|
| Howard et al. [66] | 2011 | 24 (all femoral) | 64 | Types 2 and 3 | Femoral tantalum cones | 33 | 21% required
subsequent
surgery (no aseptic loosening); all femoral cones appeared well-fixed radiographically, with no evidence of complications related to the cone |
|
| Lachiewicz et al. [59] | 2012 | 33 (9/24) | 64.6 | N/A | Femoral or tibial cone | 39.6 | 2 cones removed for infection at 12 months, 1 revision for loosening
Metaphyseal fixation with tantalum cones can be achieved |
|
| Kamath et al. [56] | 2012 | 23 | 62 | N/A | Porous tantalum (PT) patellar components | 92.4 | All patellae had less than 10 mm residual thickness; in 2 cases direct sutures to the tendons; 4 revision surgeries; 83% of survivorship; failures were associated with avascular necrosis of the residual bone and direct suture to the extensor apparatus |
|
| Villanueva-Martínez et al. [60] | 2013 | 21 (18/11) | 73.3 | Types 2 and 3 | Femoral and tibial tantalum cones | 36 | All metaphyseal cones showed evidence of stable osteointegration; good or excellent results in 17 cases |
|
| Schmitz et al. [61] | 2013 | 44 | 72 | Types 2 and 3 | Femoral and tibial tantalum cones | 37 | 2 rerevisions for aseptic loosening; favorable clinical and radiological outcomes using tantalum cones in managing significant bone losses in revision TKA |
|
| Rao et al. [62] | 2013 | 29 | 72 | Types 2 and 3 | Femoral and tibial tantalum cones | 36 | No radiolucent lines; good osteointegration one year after surgery; no evidence of collapse or loosening |
|
| Jensen et al. [67] | 2014 | 36 (all tibial) | 69 | Types 2 and 3 (75%) | Tantalum tibial cones | 47 | 4 rerevisions (2 infections, 1 aseptic loosening, 1 hyperextension); 27 patients had no radiological loosening |
|
| Derome et al. [63] | 2014 | 29 | 70 | Types 2 and 3 | Femoral and tibial tantalum cones | 33 | No evidence of loosening or migration of the constructs; no complication |
|
| Boureau et al. [54] | 2015 | 7 (all femoral) | 65 | Types 2 and 3 | 2-tantalum-cone technique | 17 | No complication; no migration of the femoral cones |
|
| De Martino et al. [68] | 2015 | 26 (13/13) | 73 | Types 2 and 3 | Femoral and tibial tantalum cones | 72 | 2 reoperations for infection, but cones were osteointegrated; no evidence of loosening; tantalum cones for reconstruction of massive bone defects provided secure fixation and outcomes at average follow-up of 6 years |
|
| Brown et al. [69] | 2015 | 83 | 69 | Types 2 and 3 (primary and revision surgery) | Femoral and tibial tantalum cones | 40 | 12% revision (one aseptic loosening); of the unrevised knee, 99% had complete osteointegration
45% experienced at least one complication |
|
| Kamath et al. [70] | 2015 | 66 | 67 | Types 2 and 3 | Tibial tantalum cones | 70 | Improvement of mean Knee Society Score; one patient had progressive radiolucent line; 3 cones were revised: 1 infection, 1 aseptic loosening, 1 periprosthetic fracture; revision-free survival of the tibial cone component was >95% at the time of the latest follow-up |
