Seven ruptures occurred from the patellar origin medially and the tibial attachment laterally in a Z-shaped pattern. Four were completely distal, and 2 were completely proximal ruptures. All patients exhibited early flexion loss, but 11 of 13 patients maintained full, terminal hyperextension throughout treatment. The mean postoperative side-to-side flexion deficit was 33\u00b0 at 1 month, 6\u00b0 at 3 months, and 3\u00b0 at latest follow-up at a mean of 4.8 years after tendon repair (range, 1-16 years). By International Knee Documentation Committee (IKDC) criteria, 10 patients had normal flexion, and 3 were nearly normal at latest follow-up. Twelve patients had normal extension, and 1 had nearly normal extension at latest follow-up. Mean isokinetic quadriceps muscle strength was 68.7% of the other side at 3 months after repair and 100.0% at latest follow-up, occurring at a mean of 47.5 months (range, 12-120 months). At a mean of 2 years (range, 1-4 years) after repair, the mean modified Noyes subjective score was 89.8 \u00b1 9.2.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Patellar tendon ruptures are rare after ACL graft harvest. These ruptures usually occur in either a proximal-medial and distal-lateral pattern or an entirely distal pattern, in contrast to the proximal-only tear pattern commonly observed in unharvested patellar tendons. Good objective and subjective results were achieved with repair of postoperative patellar tendon ruptures using suture anchors and Dall-Miles cable augmentation, followed by aggressive, immediate range of motion exercises.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/0363546512449815","type":"journal-article","created":{"date-parts":[[2012,6,17]],"date-time":"2012-06-17T18:51:48Z","timestamp":1339959108000},"page":"1834-1841","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":31,"title":["Tear Patterns, Surgical Repair, and Clinical Outcomes of Patellar Tendon Ruptures After Anterior Cruciate Ligament Reconstruction With a Bone\u2013Patellar Tendon\u2013Bone Autograft"],"prefix":"10.1177","volume":"40","author":[{"given":"Rodney W.","family":"Benner","sequence":"first","affiliation":[{"name":"Campbell Clinic, Department of Orthopaedic Surgery, University of Tennessee, Memphis, Tennessee"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.
