Abstract

In recent years, there has been an increasing debate regarding the possible role of minimally invasive (MIS) total hip arthroplasty (THA). We conducted a questionnaire survey of the Hip Society members and compared the responses of the surgeons with those of patients who were being considered for THA. 80% of surgeons who completed the survey admitted to performing MIS THA, of whom two thirds defined MIS as small incision. Of surgeons, 74% had encountered some complication related to MIS THA; 67% of patients had not heard of MIS THA. The knowledge regarding MIS THA expressed by 80% of patients was either inaccurate or not substantiated by any studies. This survey highlights the inadequacy of our current understanding of MIS THA and lack of education on the part of the patients.

Materials and Methods

In 2004, all 96 members of the American Hip Society were sent a mail survey regarding MIS hip arthroplasty. The survey questionnaires consisted of 25 questions (Appendix A) developed with the assistance of the medical survey division of the Department of Epidemiology at our institution to capture the opinion and experience of these experts with regard to MIS THA. A similar survey (Appendix B) was also designed to capture the opinion and knowledge of patients who were candidates for THA. The

Results

Of 96 members of the Hip Society who were contacted, 45 returned the completed questionnaires. Completed surveys by 45 patients who had heard of MIS surgery were included in the final analysis.

Discussion

Minimally invasive THA has become a popular issue because of the enormous implications associated with the concept, including market share (for surgeons, hospital, and implant manufactures), patient outcomes, and complications. The surgeons, administrators, and more importantly, the patients, have devoted immense attention to this issue in recent years. It has become common place for reconstructive orthopedic surgeons to face patients who speak about and possibly request MIS hip or knee

    We reviewed 386 identified abstracts and determined that 172 publications were directly related to minimally invasive hip arthroplasty. These publications were categorized as review articles (n = 69), scientific studies (including comparative studies and case series, n = 64), randomized controlled trials (RCTs, n = 9) [1-9], cadaveric studies (n = 8) [10-17], letters to the editor (n = 6), case reports (n = 3) [18-20], questionnaires (n = 3) [21-23], surgical techniques (n = 3) [24-26], internet information (n = 2) [27,28], unavailable articles (n = 2), economic analyses (n = 2) [29,30], and an RCT outline plan (n = 1) [31]. Within the scientific study group of 64 studies, we found that 4 series of patients were reported twice, so 1 of each of those series was removed from additional analysis, leaving 60 scientific studies and a total of 168 articles for analysis.

    While the debate regarding the potential benefits of minimally invasive total hip arthroplasty continues, the influence of a variety of factors on the outcome of total hip arthroplasty is not completely known. In a recent survey of members of the Hip Society in 2004, 77% of the forty-five surgeons confirmed that they had implemented changes in their routine practice when performing minimally invasive total hip arthroplasty32. These included the use of preemptive analgesia, preoperative patient education, changes in anesthesia, the use of different surgical instruments, and the use of an aggressive rehabilitation protocol33.
