We hypothesized that \u201ctime-based\u201d criteria to declare safe return to sport could not be reliable to predict functional recover. Fifty-eight young athletic patients were selected after isolated reconstruction of MPFL. The minimum follow-up was 8\u2009months. All the patients were evaluated subjectively with Kujala and Short Form 36 (SF-36) scores and objectively through a standardized computer-assisted physical battery of seven tests (Back in Action, Corehab). No patient was lost at the end point of follow-up and no recurrence of patellar dislocation was reported. At 8\u2009months, 31 patients (53.4%) returned to sport at preoperative levels, and 23 (39.6%) participated in sports at lower levels. The subjective evaluation reported an increase of Kujala (60\u201392.7) and SF-36 score (28.6\/25.4\u201352.2\/53.6). At computer-assisted objective assessment, only 23 patients (39.6%) fulfilled the criteria for safe return to sport, while 31 (53.4%) got an insufficient outcome and 4 (6.9%) failed to complete the test. From our data, clinical scores after MPFL reconstruction provide only little insight into return to sport. The introduction of a computer-assisted objective analysis in the decision-making process for proper return to sport is necessary to evaluate functional recovery and dynamic knee stability.<\/jats:p>","DOI":"10.1055\/s-0039-1696647","type":"journal-article","created":{"date-parts":[[2019,9,5]],"date-time":"2019-09-05T07:35:11Z","timestamp":1567668911000},"page":"363-371","source":"Crossref","is-referenced-by-count":17,"title":["Timing
