Abstract

Total hip and total knee arthroplasties (n = 951) were retrospectively reviewed to determine the cost-effectiveness of routine pathologic examination of surgical specimens in primary total hip and total knee replacements. Discrepancies between the postoperative diagnosis and the final pathologic diagnoses were recorded. Of the 951 cases reviewed, 27 (2.8%) noted conflicting postoperative and pathologic diagnosis. In all cases, the discrepancy was between a postoperative diagnosis of osteoarthritis and pathologic diagnosis of vascular necrosis. No new cases of neoplasia or inflammatory arthropathy were noted based on the pathologic interpretation. Sixteen of these discrepancies (5.1%) and were noted in total hip arthroplasties, and 11 (1.7%) were noted in total knee arthroplasties. In no case was postoperative medical or surgical treatment altered. Based on this review, strong consideration should be given to the elimination of routine pathologic evaluation of surgical specimens during primary joint arthroplasty, leaving this pathologic evaluation optional, at the discretion of the orthopaedic surgeon, rather than mandatory.

    Lin et al. arrived at essentially infinite cost per QALY by not finding any gain in QALY (QALY = 0) with routine pathology [4,6]. Of the articles that commented on the need for routine pathologic examination of femoral heads retrieved during THA, 58% (7 of 12 articles) advised against this practice as it was not found to change patient management [4,5,8,10,12,13,15]. It is our opinion that the remaining 5 articles that favored routine pathologic examination did so after mischaracterizing many pathologic diagnoses that did not impact patients’ clinical course as discordant [6,7,9,11,17].

    The arguments made in support of this practice are eliminating the HP examination cost benefiting the patient. Generally, there is a lack of disagreement between the clinical and pathological diagnosis, and minor discrepancy in the diagnosis usually does not change the patient management.12–17 This point of view advocated by these research papers assumes that eliminating the HP examination in no way compromises the quality of care delivered to the individual patient.
