Patellar Tendon Reconstruction Using Semitendinosus Autograft With Preserved Distal Insertion for Treatment of Patellar Tendon Rupture After Bone–Patellar Tendon–Bone ACL Reconstruction: A Case Report

Patellar Tendon Reconstruction Using Tibialis Posterior Allograft for Treatment of Patellar Tendon Rupture After Bone-Patellar Tendon-Bone Anterior Cruciate Ligament Reconstruction

“…The patellar tendon rupture described in this report was a midsubstance tear. This injury pattern has only been described twice previously, 7,14 with both reports describing different techniques of surgical repair.…”

“…2 Patellar tendon rupture following BPTB ACL reconstruction is an uncommon complication, with studies demonstrating occurrence in 0.06% to 0.24% of cases. 3,4 Patellar tendon rupture commonly occurs in the early postoperative period from a slip and fall accident, [3][4][5][6][7][8] and case reports have described various locations of tendon rupture. [3][4][5][6][7][8][9][10][11][12][13][14][15][16] The majority of these injuries have been complete distal or proximal ruptures, avulsions, or Z-type ruptures with the medial side of the tendon tearing proximally and the lateral side tearing distally.…”

Patellar Tendon Rupture 12 Years after ACL Reconstruction with BPTB Autograft

“…The reported incidence of PTR following ACLR with ipsilateral BPTB autograft ranges from 0.05% to 0.24% [ 1 , 5 , 7 ]. The majority of tears occur in the early postoperative period, but there have been six reports of tears occurring in the 7-month to 10-year range since this complication was first described by Bonamo et al in 1984 [ 2 – 6 , 8 – 10 ]. To our knowledge, this is the first report of a PTR greater than 10 years after ACLR with BPTB autograft in a knee with prior hamstring tendon (HT) harvest for an elbow ulnar collateral ligament reconstruction.…”
