Suspending the\n\t\t\t\t\tdiagnosis and treatment of non-virus related diseases for longer periods of time\n\t\t\t\t\tis not a viable option since this would only exacerbate problems on the patient\n\t\t\t\t\tand national level. The need for alternative treatment modalities increased\n\t\t\t\t\trather quickly. So far, telemedical applications have mainly focused on\n\t\t\t\t\tteleradiological diagnosis, follow-up and monitoring of psychiatric and internal\n\t\t\t\t\tdiseases, as well as geriatric patient care. As far as these authors are aware,\n\t\t\t\t\torthopaedic physical examination of the knee joint, including trauma work-up,\n\t\t\t\t\thas not been the subject of any studies to date. This feasibility study explores\n\t\t\t\t\thow video consultation can be designed and implemented in the context of history\n\t\t\t\t\ttaking and physical examination in knee joint complaints.<\/jats:p><jats:p>\n          Material and Method 21 patient actors (PA) with simulated complaints of\n\t\t\t\t\tthe knee joint were examined individually for each diagnosis, first via video\n\t\t\t\t\tconsultation and then directly by a specialist (SP). One PA group has a medical\n\t\t\t\t\tbackground, the other was made up of laypersons. The time was measured for both\n\t\t\t\t\ttypes of consultation. The physician documented the detected symptoms, the\n\t\t\t\t\tquality of implementation of the self-examination steps, and the derived\n\t\t\t\t\tdiagnosis on an assessment form. After completion of both consultation sessions,\n\t\t\t\t\tthe PAs were handed a questionnaire on the respective examination modality.<\/jats:p><jats:p>\n          Results With the video consultation the examination lasted 8.63 (\u00b1\u20092.5)\n\t\t\t\t\tminutes on average and with the regular consultation in person 5.63 (\u00b1\u20091.7)\n\t\t\t\t\tminutes (p\u2009&lt;\u20090.001). For the group with medical background the examination\n\t\t\t\t\tlasted 7.67 (\u00b1\u20091.4) minutes on average, while for the lay group the video\n\t\t\t\t\tconsultation took 9.7 (\u00b1\u20093.1) minutes (p\u2009=\u20090.049). With increased age, the video\n\t\t\t\t\tconsultation was prolonged (p\u2009=\u20090.032; r\u2009=\u20090.47). The mean value for\n\t\t\t\t\tself-examination of leg axis, gait pattern and degrees of freedom was 9.32\n\t\t\t\t\t(\u00b1\u20090.4) of 10 points. The following functional tests resulted in lower mean\n\t\t\t\t\tvalues (points): Payr 7.2 (\u00b1\u20092.3), Merke 5.9 (\u00b1\u20092.8), no-touch Lachmann 6.4\n\t\t\t\t\t(\u00b1\u20092.7), gravity sign-recurvatum 6.7 (\u00b1\u20092.4). The mean grade by the PAs for the\n\t\t\t\t\tfeasibility of self-examination was 2.43 (\u00b1\u20090.98) out of 5 points.<\/jats:p><jats:p>\n          Conclusion The video consultation for musculoskeletal complaints of the\n\t\t\t\t\tknee joint allows exploratory remote examination and helps to minimise the\n\t\t\t\t\tnumber of patients in hospitals and practices. It takes longer for the physician\n\t\t\t\t\tto perform and does not permit functional testing for ligament injuries of the\n\t\t\t\t\tknee joint. In its present form, telemedical examination is not able to fully\n\t\t\t\t\treplace personal consultation.<\/jats:p>","DOI":"10.1055\/a-1246-3615","type":"journal-article","created":{"date-parts":[[2020,11,24]],"date-time":"2020-11-24T23:54:05Z","timestamp":1606262045000},"page":"93-98","source":"Crossref","is-referenced-by-count":7,"title":["A Feasibility Pilot Study on the Use of Telemedicine for\n\t\t\t\t\tthe Examination of the Knee Joint"],"prefix":"10.1055","volume":"160","author":[{"given":"Sebastian","family":"Scheidt","sequence":"first","affiliation":[{"name":"Department of Orthpaedics and Trauma Surgery, Bonn University Medical\n\t\t\t\t\tCentre, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Kehrer","sequence":"first","affiliation":[{"name":"Department of Orthpaedics and Trauma Surgery, Bonn University Medical\n\t\t\t\t\tCentre, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kristian","family":"Welle","sequence":"first","affiliation":[{"name":"Department of Orthpaedics and Trauma Surgery, Bonn University Medical\n\t\t\t\t\tCentre, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthias D.","family":"Wimmer","sequence":"first","affiliation":[{"name":"Department of Orthpaedics and Trauma Surgery, Bonn University Medical\n\t\t\t\t\tCentre, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Max","family":"Jaenisch","sequence":"additional","affiliation":[{"name":"Department of Orthpaedics and Trauma Surgery, Bonn University Medical\n\t\t\t\t\tCentre, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hans","family":"Goost","sequence":"additional","affiliation":[{"name":"Department of Orthpaedics and Trauma Surgery, Wermelskirchen Hospital,\n\t\t\t\t\tGermany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dieter Christian","family":"Wirtz","sequence":"additional","affiliation":[{"name":"Department of Orthpaedics and Trauma Surgery, Bonn University Medical\n\t\t\t\t\tCentre, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christof","family":"Burger","sequence":"additional","affiliation":[{"name":"Department of Orthpaedics and Trauma Surgery, Bonn University Medical\n\t\t\t\t\tCentre, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1458-2825","authenticated-orcid":false,"given":"Koroush","family":"Kabir","sequence":"additional","affiliation":[{"name":"Department of Orthpaedics and Trauma Surgery, Bonn University Medical\n\t\t\t\t\tCentre, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2020,11,24]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"727","DOI":"10.1056\/NEJMoa2001017","article-title":"A Novel Coronavirus from Patients with Pneumonia in China","volume":"382","author":"N Zhu","year":"2020","journal-title":"N Engl J Med"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"1679","DOI":"10.1056\/NEJMp2003539","article-title":"Virtually Perfect?
