Abstract

Orthopaedic oncologic surgery requires resection with a safe margin as inadequate surgical margin leads to unfavorable results with an increased rate of local tumor re- currence [1]. Computer Navigation Assisted Surgery (CAS) and Patient Specific In- strumentation (PSI) have been reported to increase accuracy and predictability of tumor resections [2-6]. The technically demanding joint-preserving surgery that re- tains the native joint with the better function may be benefited from the new tech- niques [7]. CAS has the advantages of real-time intraoperative guidance of the bone resections but requires bulky and costly facilities [5]. PSI is a simple option of repli- cating surgical plan but lacks intraoperative image feedback on the surgery [5,6]. As primary bone sarcoma is uncommon, clinical studies for meaningful comparison of the two techniques may not be feasible. The cadaver study was to investigate the surgical accuracy of CAS and PSI in joint-preserving tumor surgery of knee joint.
