Abstract
We performed a functional analysis of massive knee replacements after extra -articular resection of primary bone tumors. Patients did not score as high ly on the Musculoskeletal Tumour Society Score and Knee Society Score (P le ss than or equal to .01) as patients who had undergone intra-articular rese ction. Lower scores were achieved for emotional acceptance (P less than or equal to .01 ). functional restriction (P less than or equal to .05), walki ng distance (P less than or equal to .05). and managing stairs (P less than or equal to .05). These patients had a significantly greater extension lag (P less than or equal to .01) and greater fixed flexion (P less than or eq ual to .05). This functional deficit is primarily due to a compromised exte nsor mechanism inherent in the type of surgical resection necessary to achi eve adequate removal of the tumor.
