Exclusion criteria included Kellgren-Lawrence grade \u22653 osteoarthritis, concurrent ligamentous or realignment procedures, all-inside suture anchor repair, and concomitant lateral meniscal tears. The clinical outcome measures included conversion to knee arthroplasty, the shortened Knee injury and Osteoarthritis Outcome (KOOS) Jr, International Knee Documentation (IKDC), and Veterans RAND 12-Item Health Survey (VR-12) scores. Clinical failure was defined as failing to achieve the minimal clinically important difference (MCID) for \u22651 PROM. The MCID and Patient Acceptable Symptom State (PASS) thresholds were derived from a peer-reviewed study and were as follows: IKDC (MCID, 10.2; PASS, 67.8), KOOS Jr (MCID, 10.4; PASS, 71.9) and VR-12 Physical (MCID, 6.1; PASS, 47.8).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>A total of 38 patients who met inclusion criteria and underwent transtibial root repair before March 2019 were retrospectively identified, of which 36 (94.7%) were available for follow-up at mean 65.8 \u00b1 6.7 months (range, 60-81). Of this total, 5 patients (13.9%) converted to arthroplasty (mean \u00b1 SD, 41.8 \u00b1 28.0 months). Transtibial pullout repair had an overall survivorship of 97.2%, 94.4%, and 91.6% at the 1-year, 2-year, and 5-year time points, while 2 patients failed after 60 months postoperatively, for an 86.1% arthroplasty-free survivorship at mean 65.8 months. MCID and PASS achievement rates at final follow-up for KOOS Jr were 74.2% and 51.6%, respectively. Three patients (8.3%) failed to achieve MCID for any 1 of the 3 PROMs while 28 patients (77.8%) achieved the MCID for \u22651 PROM.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Clinically significant outcomes for KOOS Jr were achieved in 74.2% and 51.6% of patients undergoing transtibial pullout repair for isolated MMPRT at 5-year follow-up.
