The purpose of this study was, therefore, to evaluate sports activity after arthroscopic BMS at long\u2010term follow\u2010up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Sixty patients included in a previously published randomized\u2010controlled trial were analyzed in the present study. All patients had undergone arthroscopic debridement and BMS for OCLT. Return to sports, level, and type were assessed in the first year post\u2010operative and at final follow\u2010up. Secondary outcome measures were assessed by standardized questionnaires with use of numeric rating scales for pain and satisfaction and the Foot and Ankle Outcome Score (FAOS).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The mean follow\u2010up was 6.4 years (SD\u2009\u00b1\u20091.1 years). The mean level of activity measured with the AAS was 6.2 pre\u2010injury and 3.4 post\u2010injury. It increased to 5.2 at 1 year after surgery and was 5.8 at final follow\u2010up. At final follow\u2010up, 54 patients (90%) participated in 16 different sports. Thirty\u2010three patients (53%) indicated they returned to play sport at their pre\u2010injury level. Twenty patients (33%) were not able to obtain their pre\u2010injury level of sport because of ankle problems and eight other patients (13%) because of other reasons. Mean NRS for pain during rest was 2.7 pre\u2010operative, 1.1 at 1 year, and 1.0 at final follow\u2010up. Mean NRS during activity changed from 7.9 to 3.7 to 4.4, respectively. The FAOS scores improved at 1 year follow\u2010up, but all subscores significantly decreased at final follow\u2010up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>At long\u2010term follow\u2010up (mean 6.4 years) after BMS for OCLT, 90% of patients still participate in sports activities, of whom 53% at pre\u2010injury level. The AAS of the patients participating in sports remains similar pre\u2010injury and post\u2010operatively at final follow\u2010up. A decrease over time in clinical outcomes was, however, seen when the follow\u2010up scores at 1 year post\u2010operatively were compared with the final follow\u2010up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of evidence<\/jats:title>\n                    <jats:p>Level II.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00167-020-06250-8","type":"journal-article","created":{"date-parts":[[2020,9,12]],"date-time":"2020-09-12T02:02:48Z","timestamp":1599876168000},"page":"1562-1569","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Bone marrow stimulation for talar osteochondral lesions at long\u2010term follow\u2010up shows a high sports participation though a decrease in clinical outcomes over time"],"prefix":"10.1002","volume":"29","author":[{"given":"Kaj T.
