Benign Bone Tumors When They Coexist with Common Orthopaedic Conditions

Abstract

Benign and malignant bone tumors around the knee can be encountered with concomitant orthopaedic disease. As such, it is important to recognize these oncologic processes that may impact or alter the routine treatment of more common orthopaedic processes. Frequently, these rare oncologic conditions are discovered only through the evaluation of acute injuries as in the setting of fractures or sports injuries. Other times, they are encountered when evaluating chronic entities, such as arthroplasty. This article aims to provide general guidelines and management strategies for benign bone tumors when they coincide with common orthopaedic conditions around the knee.

“…Instead, a comprehensive diagnostic work-up should be followed including histologic diagnosis and grading, age, clinical findings, history, and genetic expression before definitive surgical, oncologic, or imageguided interventions. 14,16 Novel and established functional imaging techniques such as single-photon emission computed tomography/CT, positron emission tomography/CT (►Fig. 2), MR perfusion (perfusion-weighted imaging [PWI]), MR diffusion (diffusion-weighted imaging), and dynamic contrast enhancement (DCE) analysis allow accurate visualization of the active and most cellular components of the tumors that can then be targeted with image-guided interventions, [19][20][21] as well as permitting assessment of response to such interventions on subsequent follow-up 22 (►Fig.…”

“…1 Failure to identify and consider biological behaviors of such tumors can result in inappropriate surgical or interventional strategies, use of unsuitable surgical implants, and increased morbidity/mortality rates, both in childhood as well as later in life. 1,14 In this article, we share our experience in bone and MSK soft tissue ablation interventions including benign tumors, sarcoma and metastases, and myeloma from several internationally renowned centers, aiming to provide a comprehensive overview of methods to tackle common tumors (primary and secondary), axial and nonaxial, that may be encountered in an MSK practice. We examine the utility of the versatile image-guided interventional repertoire, which as such allows for patient-tailored management plans that may involve single or combined procedures, guided by one or more imaging modality.…”
