Talocalcaneal and talonavicular relationships were measured and the degree of osteo-arthritic change in the ankle and talonavicular joints was assessed. The functional results were evaluated using a modified Laaveg-Ponseti score. The talocalcaneal (TC) angles in the clubfeet were significantly lower in both anteroposterior (AP) and lateral projections than in the unaffected feet (p &lt; 0.001 for both views). There was significant medial subluxation of the navicular in the clubfeet compared with the unaffected feet (p &lt; 0.001). Severe osteoarthritis in the ankle joint was seen in seven feet (8%) and in the talonavicular joint in 11 feet (12%). The functional result was excellent or good (\u2265 80 points) in 29 patients (48%), and fair or poor (&lt; 80 points) in 31\u00a0patients (52%). Patients who had undergone few (0 to 1) surgical procedures had better functional outcomes than those who had undergone two or more procedures (p &lt; 0.001). There was a significant correlation between the functional result and the degree of medial subluxation of the navicular (p &lt; 0.001, r<jats:sup>2<\/jats:sup>= 0.164), the talocalcaneal angle on AP projection (p &lt; 0.02, r2 = 0.025) and extent of osteoarthritis in the ankle joint (p &lt; 0.001).<\/jats:p><jats:p>We conclude that poor functional outcome in patients with congenital clubfoot occurs more frequently in those with medial displacement of the navicular, osteoarthritis of the talonavicular and ankle joints, and a low talocalcaneal angle on the AP projection, and in patients who have undergone two or more surgical procedures. However, the ankle joint in these patients appeared relatively resistant to the development of osteoarthritis.<\/jats:p>","DOI":"10.1302\/0301-620x.94b11.28877","type":"journal-article","created":{"date-parts":[[2012,10,29]],"date-time":"2012-10-29T14:19:30Z","timestamp":1351520370000},"page":"1522-1528","source":"Crossref","is-referenced-by-count":8,"title":["Low prevalence of osteoarthritis in patients with congenital clubfoot at more than 60\u00a0years\u2019 follow-up"],"prefix":"10.1302","volume":"94-B","author":[{"given":"H.","family":"Wallander","sequence":"first","affiliation":[{"name":"G\u00e4vle Hospital, Department of Orthopaedic Surgery, SE801 87 G\u00e4vle, Sweden."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Saeb\u00f6","sequence":"additional","affiliation":[{"name":"G\u00e4vle Hospital, Department of Radiology, SE801 87 G\u00e4vle, Sweden."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Jonsson","sequence":"additional","affiliation":[{"name":"Sk\u00e5ne University Hospital, Centre for Medical Imaging and Physiology, SE22241 Lund, Sweden."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"Bj\u00f6nness","sequence":"additional","affiliation":[{"name":"Sahlgrenska University Hospital, Department of Orthopaedic Surgery, SE413 46 Gothenburg, Sweden."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.","family":"Hansson","sequence":"additional","affiliation":[{"name":"Queen Silvia Children\u2019s Hospital, SE41685 Gothenburg, Sweden."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"42","reference":[{"key":"r1","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199510000-00002"},{"key":"r2","doi-asserted-by":"publisher","DOI":"10.1097\/01241398-199701000-00009"},{"key":"r3","doi-asserted-by":"publisher","DOI":"10.1007\/s00256-003-0620-6"},{"key":"r4","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-200605000-00009"},{"key":"r5","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.91B10.22796"},{"key":"r6","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198062010-00004"},{"key":"r7","doi-asserted-by":"crossref","first-page":"30","DOI":"10.1097\/00003086-198110000-00003","volume":"160","author":"Ponseti IV","year":"1981","journal-title":"Clin Orthop Relat Res"},{"key":"r8","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.59B4.925058"},{"key":"r9","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.48B1.40"},{"key":"r10","doi-asserted-by":"publisher","DOI":"10.1097\/01241398-200101000-00013"},{"key":"r11","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.F.00438"},{"key":"r12","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.67B5.4055883"},{"key":"r13","doi-asserted-by":"publisher","DOI":"10.1097\/01202412-200010000-00013"},{"key":"r14","doi-asserted-by":"publisher","DOI":"10.3109\/17453677508989272"},{"key":"r15","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198062050-00012"},{"key":"r16","doi-asserted-by":"publisher","DOI":"10.1002\/sim.4780132310"},{"key":"r17","doi-asserted-by":"publisher","DOI":"10.1002\/sim.4780132308"},{"key":"r18","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0258(19981230)17:24<2923::AID-SIM104>3.0.CO;2-#"},{"key":"r19","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.182.5.1821279"},{"key":"r20","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.60B4.711805"},{"key":"r21","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198264050-00002"},{"key":"r22","doi-asserted-by":"publisher","DOI":"10.1097\/01241398-198809000-00018"},{"key":"r23","first-page":"219","volume":"248","author":"Lau JH","year":"1989","journal-title":"Clin Orthop Relat Res"},{"key":"r24","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-007-0448-0"},{"key":"r25","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-008-0543-6"}],"container-title":["The Journal of Bone and Joint Surgery.
