Purpose: To determine the level of promotion of minimally invasive surgery (MIS) & computer assisted orthopaedic surgery (CAOS) in total knee replacement (TKR) through internet sites by BASK members.

Methods: We obtained an updated list of active members of BASK in March 2007 and permission from the executive committee to undertake this study. Standard search engines commonly used in our daily lives (viz. Google, Yahoo and Ask.com) were used to search for websites related to each surgeon during Sep–Nov 2007 period. The surgeon’s name, initials and job title thereof were used as keywords in conducting the search. Thus for each surgeon, all websites found were browsed and evaluated for MIS/CAOS and TKR/UKR information. Both direct (surgeon’s personal website/private practice) and indirect (group practice/hospital/university affiliation) information from these websites were reviewed and a standard pre-formed questionnaire proforma was filled in against that particular surgeon.

Results: A total of 178 websites were found for 405 members (392 inland + 13 overseas). 2.8% and 4.5% made direct and indirect reference to MIS TKR respectively. The most commonly listed benefits of MIS were quicker recovery, smaller incision and hence lesser pain. Very few specific risks of MIS were outlined by these websites. None of the websites quoted any peer-reviewed publication to support their claims. CAOS was discussed in 1.7% and 2.8% of these sites respectively.

Conclusion: Our study suggests that many active members do not have personal websites and these procedures are not commonly promoted by them via the internet. Many of these are often associated indirectly with group practice/institutional affiliation websites which may not necessarily be endorsed the surgeon. Our plan in near future is to monitor the changes in internet dissemination of information and close the audit loop by next year.
