Results Evaluation of Resection-Reconstruction of Knee Periarticular Tumors

Oncological resection and articular reconstruction through modular tumor prosthesis is a challenge for the surgeon, but at the same time gives the patient the certainty of keeping the function and hope for healing. Due to technical evolution, the recovery of osteoarticular post-resection tumor is today much more versatile and permissive, providing the comfort of the orthopedic oncologist surgeon during reconstruction and at the same time the patient satisfaction. Purpose of the paper. Short-term and medium-term evaluation of surgical treatment outcome of bone oncological pathogenesis of the knee with modular tumor prosthesis. Material and method. Recording based on the unique tumor registry of the Clinic in a monocentric, retrospective continuously study between 2009 and 2017, of all orthopedic oncology patients with malignant/ borderline tumors with metaphyso-epiphyseal knee periarticular involvement, beneficiaries of the resection-reconstruction with prosthesis modular tumor - a total of 21 cases. Case analysis included details of histopathological types of tumors, followed by Enneking staging, which was performed, alongside classical demographics. The Malaware oncological resection technique was followed and the learning curve and results of the prostatic modular prosthetic reconstruction were registered, considering failure for any of the following reasons: revision, necessity exhaustion of the prosthesis - infection, relapse, or amputation. The functional evaluation was based on the revised Muscular-skeletal Tumor Society Score (rMSTS). Results and discussions. Only one case of failure was registered - a periprosthetic infection. The overall rate of apparently postoperative complications followed the literature data for this type of intervention - 40-50%. Compared to amputation, the lower limb salvage process in the knee malignant tumors has proven to be cost-effective and has contributed to improving the quality of life, becoming one of the sustainable options for onco-surgical management in good cases selected. The limits of the study are determined by the relatively short duration of follow-up, and the apparently large number of complications is nevertheless included in the international statistics related to such interventions.
