| Summary: | Purpose. To investigate consultant surgeons' knowledge about the costs of implants for various joint surgeries. Methods. Questionnaires were distributed to consultant orthopaedic surgeons at 2 hospitals. Respondents were asked to estimate the implant costs of any brand for low-demand and high-demand total hip replacement (THR), total knee replacement (TKR), uni-compartmental knee replacement, arthroscopy shaver blade, total anterior cruciate ligament (ACL) fixation, and meniscal repair. The actual cost of each implant was obtained from the manufacturer. Results. 16 consultant surgeons completed the questionnaires. The respective mean estimated and actual costs for a low-demand THR implant were £1714 (range, £600–3000) and £1448 (range, £985–2335), with an overestimation of 18.4%. The respective costs for a high-demand THR implant were £2172 (range, £600–6000) and £1737 (range, £1192–2335), with an overestimation of 25%. The respective costs for a TKR implant were £1550 (range, £600–6000) and £1316 (range, £995–1535), with an overestimation of 17.8%. The respective costs for a uni-compartmental knee replacement implant were £1040 (range, £600–2000) and £1296 (range, £698–1470), with an underestimation of 19.7%. The respective costs for an arthroscopy shaver blade were £110 (range, £75–150) and £94 (range, £80–100), with an overestimation of 16.6%. The respective costs for a total ACL fixation implant were £246 (range, £80–500) and £306 (range, £272–335), with an underestimation of 19.4%. The respective costs for a meniscal repair implant were £153 (range, £50–250) and £242 (range, £170–260), with an underestimation of 37%. Conclusion. The knowledge among consultant orthopaedic surgeons about implant costs was poor. To reduce implant costs, cooperation between surgeons and hospital managers and measures to increase surgeons' awareness about cost-reduction programmes are needed.
