Modified Pulvertaft on Weave Technique Restores Full Active Knee Extension in Patients With Large Chronic Quadriceps Tendon Rupture: A Case Series

Treatment of Distal Patellar Tendon Chronic Rupture: The X-Wave Technique

“…2 Chronic injuries to the extensor mechanism are complex to treat. 3 The proximal retraction of the quadriceps tendon makes the correct distal positioning of the patella difficult. [3][4][5][6] Patellar tendon injury is not an uncommon misdiagnosis at the emergency leading to chronic proximal retraction and, hence, to a challenging clinical scenario sometimes so intense that it may require gradual trans-osseous traction and a two-stage PT reconstruction.…”

[3][4][5][6] Patellar tendon injury is not an uncommon misdiagnosis at the emergency leading to chronic proximal retraction and, hence, to a challenging clinical scenario sometimes so intense that it may require gradual trans-osseous traction and a two-stage PT reconstruction. 4 Additionally, in the cases of chronic PT rupture, different techniques involving auto or allograft augmentation, reinforcement, and combination of other varying fixation devices were described aiming to appropriately correct the patella height and restore soft tissue integrity.…”
