Table 1

Some of the complicated cases this technique was developed to solve.

Patient Age Status Surgery Post-Operative Follow up time Patient specifics Outcomes
Female 49

  1. TKR

  2. Quadriceps tendon suture

  3. Insufficiency of the extensor apparatus with patella baja and patellar instability

  4. Complete avulsion of the vastus medialis and medial retinaculum

 Suture of the quadriceps, vastus medialis and retinaculum with augmentation with the vascular graft. Tibial tuberosity transfer for patellar tracking improvement 6-week full extension brace 2 years Heavy smoker

  • Full Extension

  • Patellar stability

  • 90° Flexion
Male 75

  1. Chronic rupture of quadriceps tendon

  2. Patella baja with patellar tendon shortening

  3. Failed primary repair surgery

 Z plasty of the patellar tendon + reinsertion of the quadriceps tendon in the patella with augmentation with the vascular graft. 6-week full extension brace 2 years

  • Full extension

  • No pain

  • Autonomous

  • Flexion deficit (75°)
Female 60

  1. TKR

  2. TKR revision

  4. Laxity of the contralateral extensor allograft reconstruction

 Reconstruction of the extensor apparatus with vascular graft + retensioning and augmentation of the allograft with the vascular prosthesis 3 months extension brace 3 years Multiple surgeries on the knee

  • Full extension

  • Straight leg raising
