We correlated tunnel widening with clinical factors, knee scores, KT\u20101000 and isokinetic muscle strength to determine the clinical significance of this finding. Seventy\u2010three patients at least 12\u00a0months post\u2010ACL reconstruction were evaluated. Thirty\u2010eight patients had received a doubled semitendinous and gracilis graft and 35 a bone\u2010patella tendon\u2010bone graft. All patients underwent a similar endoscopic procedure and accelerated postoperative rehabilitation. Tunnel widening was determined using standardized anteroposterior (AP) and lateral X\u2010rays adjusted for magnification. A limited series of MRIs was performed to validate these measurements. There was a significant difference in the degree of tunnel widening between the two groups. The mean increase in femoral tunnel area in the hamstring group was 100.4% compared with a decrease of 25% in the patella tendon group (<jats:italic>P<\/jats:italic> = &lt; 0.0001). In the tibial tunnel the mean increase in the hamstring group was 73.9% compared with a decrease of 2.1% in the patella tendon group (<jats:italic>P<\/jats:italic> = &lt; 0.0001). The MRIs validated the plain film measurements. Tunnel widening did not correlate with the clinical findings, knee scores, KT\u20101000 or isokinetic muscle strength. Tunnel widening is marked in the hamstring group. Tunnel widening does not correlate with instability or a poor clinical outcome in the short term. The long\u2010term implications of this finding are still to be determined.<\/jats:p>","DOI":"10.1007\/s001670050138","type":"journal-article","created":{"date-parts":[[2002,8,25]],"date-time":"2002-08-25T03:30:30Z","timestamp":1030246230000},"page":"138-145","source":"Crossref","is-referenced-by-count":360,"title":["Tunnel widening in anterior cruciate ligament reconstruction: a prospective evaluation of hamstring and patella tendon grafts"],"prefix":"10.1002","volume":"7","author":[{"given":"M.
