Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Biomaterials Science

Background:

  • Neglected chronic patellar tendon injuries present significant functional limitations.
  • Current treatment options may involve allografts or implants, increasing complexity and cost.
  • Anatomical reconstruction is crucial for restoring knee function.

Purpose of the Study:

  • To describe a cost-effective and simple anatomical reconstruction technique for neglected chronic patellar tendon injuries.
  • To evaluate the efficacy of using hamstring tendon autograft without allograft or implants.
  • To report outcomes in patients with chronic patellar tendon injuries.

Main Methods:

  • Seven patients with neglected patellar tendon injuries underwent reconstruction using hamstring tendon autograft.

  • Patients presented with significant extensor lag and functional limitations (average IKDC score 46.8).
  • Follow-up averaged over three years.

    • Main Results:

    • All patients achieved stable knees postoperatively with no extension lag and good range of motion (mean flexion 125°).
    • Significant improvement in quadriceps strength and functional scores (average IKDC 86.8, Lysholm 92.4, Kujala 94.5).
    • Excellent outcomes reported in five patients, good outcomes in two.

    Conclusions:

    • Hamstring tendon autograft reconstruction is effective for neglected patellar tendon injuries, providing stability and excellent functional recovery.
    • This technique offers a cost-effective, simple, and anatomical solution compared to methods requiring allografts or implants.
    • The procedure demonstrates a viable alternative for managing chronic patellar tendon defects.
