Proximal Tibia osteoarticular allografts in tumor limb salvage surgery.
Clinical orthopaedics and related research, 2009Co-Authors: D. Luis Muscolo, Miguel A Ayerza, German L Farfalli, Luis A. Aponte-tinaoAbstract:Background Resection of large tumors of the Proximal Tibia may be reconstructed with endoprostheses or allografts with fixation. Endoprosthetic replacement is associated with high failure rates and complications. Proximal Tibia osteoarticular allografts after tumor resection allows restoration of bone stock and reconstruction of the extensor mechanism, but the long-term failure rates and complications are not known.

OUTCOME OF Proximal Tibia OSTEOARTICULAR ALLOGRAFTS RECONSTRUCTION AFTER TUMOR RESECTIONS
2009Co-Authors: Eduardo Abalo, Miguel A Ayerza, German L Farfalli, Luis A. Aponte-tinao, B. Politi, D. Luis MuscoloAbstract:Pupose: The purpose of this study was to analyze the outcome of Proximal Tibia osteoarticular allografts after tumor resections. Material amd Methods: We performed a retrospective study over 58 patients in which a Proximal Tibia allograft reconstruction was undertaken. All patients were followed for a minimum of 5 years and allografts survival from the date of implantation to the date of revision or the time of the latest follow-up was determined with the use of the Kaplan-Meier method. In all patients, the patellar tendon from the host was reattached by suturing to overlapped donor flaps. Patients were clinically evaluated with the MSTS score system. Results: The global rate of allograft survival was 65% +/− 12% (+/− 2 SE) at five and ten years, with no significant difference between patients who received chemotherapy and those who did not. Allografts needed to be removed in twenty patients due to 12 infection, 4 local recurrences and 4 fractures. Active knee extension was restored in all patients with an average functional score of 26.3 points. Discussion: Survival analysis showed that 65% of Proximal Tibia osteoarticular allograft reconstructions remain stable at five and ten years. Patellar tendon reconstruction with allogeneic tissue in Proximal Tibia allograft restores active knee extension with an excellent functional result. Despite the incidence of complications, Proximal Tibia osteoarticular allografts continue to be a very valuable reconstructive procedure for large defects after resection of bone tumors.

Proximal Tibia reconstruction after bone tumor resection are survivorship and outcomes of endoprosthetic replacement and osteoarticular allograft similar
Clinical Orthopaedics and Related Research, 2017Co-Authors: Jose I Albergo, Luis A Apontetinao, Miguel A Ayerza, Luis D Muscolo, German L Farfalli, C L Gaston, L Jeys, S R Carter, R M Tillman, A AbuduAbstract:Background The Proximal Tibia is one of the most challenging anatomic sites for extremity reconstructions after bone tumor resection. Because bone tumors are rare and large case series of reconstructions of the Proximal Tibia are lacking, we undertook this study to compare two major reconstructive approaches at two large sarcoma centers.

Extendible replacements of the Proximal Tibia for bone tumours
The Journal of bone and joint surgery. British volume, 2000Co-Authors: Robert J. Grimer, S R Carter, R M Tillman, M V Belthur, Paul CoolAbstract:Limb salvage is now customary in the treatment of primary bone tumours. The Proximal Tibia is a frequent site for these neoplasms but reconstruction, especially in children, is a formidable challenge. We reviewed 20 children with extendible replacements of the Proximal Tibia, all with a minimum follow-up of five years. Five died from their disease and, of the remaining 15, four had above-knee amputations for complications. Infection occurred in seven patients; in five it was related to the lengthening procedure. Aseptic loosening is inevitable in the younger children and only two have avoided a revision, amputation or other major complication; both were aged 12 years at the time of the initial surgery. Despite this, 11 children are alive with a functioning leg and a mean Musculoskeletal Tumour Society functional score of 83%. The lengthening mechanisms used in our series required extensive open operations. We are now using a simpler, minimally invasive, technique which we hope will decrease the incidence of complications. At present, the use of extendible prostheses of the Proximal Tibia remains an experimental procedure.

Endoprosthetic replacement of the Proximal Tibia
The Journal of bone and joint surgery. British volume, 1999Co-Authors: Robert J. Grimer, S R Carter, R M Tillman, R. S. Sneath, Peter Walker, Paul Unwin, P. C. ShewellAbstract:We have performed endoprosthetic replacement after resection of tumours of the Proximal Tibia on 151 patients over a period of 20 years. During this period limb-salvage surgery was achieved in 88% of patients with tumours of the Proximal Tibia. Both the implant and the operative technique have been gradually modified in order to reduce complications. An initial rate of infection of 36% has been reduced to 12% by the use of a flap of the medial gastrocnemius, to which the divided patellar tendon is attached. Loosening and breakage of the implant have been further causes of failure. We found that the probability of further surgical procedures being required was 70% at ten years and the risk of amputation, 25%. The development of a new rotating hinge endoprosthesis may lower the incidence of mechanical problems. Limb salvage for tumours of the Proximal Tibia is fraught with complications, but the good functional outcome in successful cases justifies its continued use.
