“…There are currently no reports available on a single method that has proven to be superior to others, and decisions on treatment modality are still dependent largely on the expertise and implants at hand. They include using bone cement either on its own or in conjunction with screws (Glynn and Austin [9]), bone grafting (Goldstein et al [10], Lonner et al [11]), metal augments (long stems, wedge augments, tantalum cones, metaphyseal sleeves) (Glynn and Austin [9], Mozella et al [8], Fedorka et al [12], Dalury and Barrett [13], Bugler et al [14], Huang et al [15], Vasso et al [16], Barnett et al [17], Brown et al [18], Gross and Liu [19]), structural allografts (Glynn and Austin [9], Engh and Ammeen [20], Backstein et al [21], Kuchinad et al [22]), hinged prostheses (Glynn and Austin [9], Sanguineti et al [23]) and custom-made implants (Glynn and Austin [9]). The metaphyseal sleeve is one such option in revision TKR; however, to the author's knowledge it has not been described as a treatment option for cases of complex primary knee osteoarthritis.…”
