This study found that arthroscopic double-bundle posterior cruciate ligament (PCL) reconstruction with Achilles allograft and double cross-pin fixation offers good clinical outcomes. The technique provides a reliable alternative for PCL repair, improving knee function and stability.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Biomedical Engineering

Background:

  • Posterior cruciate ligament (PCL) injuries often require surgical reconstruction to restore knee stability.
  • Arthroscopic techniques aim to minimize invasiveness while achieving robust fixation.
  • Double-bundle reconstruction aims to replicate native PCL anatomy and function more closely.

Purpose of the Study:

  • To evaluate the clinical outcomes of arthroscopic double-bundle PCL reconstruction.
  • To assess the efficacy of double cross-pin fixation on the tibial side using an Achilles tendon allograft.
  • To determine the functional and stability improvements following the procedure.

Main Methods:

  • A cohort of 22 patients underwent arthroscopic double-bundle PCL reconstruction with Achilles allograft and double cross-pin tibial fixation.

Novel Triple-Loop Technique for Suturing TFCC Injuries without Transosseous Tunnel

Published on: May 23, 2025

  • Preoperative and postoperative assessments included Lysholm knee scores, IKDC grades, Tegner activity scores, Telos stress radiographs, and KT-2000 arthrometer measurements.
  • Follow-up averaged 33 months.

    • Main Results:

    • Significant improvements were observed in Lysholm scores (64 to 88, P < 0.001) and IKDC grades (all abnormal preoperatively to 88% normal/nearly normal postoperatively).
    • Knee stability improved, with side-to-side differences reducing from 11 mm to 3 mm on Telos radiographs (P < 0.01) and KT-2000 measurements (P < 0.01).
    • Tegner activity scores increased from a preoperative median of 3 to a postoperative mean of 6.

    Conclusions:

    • Arthroscopic double-bundle PCL reconstruction using Achilles allograft with double cross-pin tibial fixation yields satisfactory clinical results.
    • The technique demonstrates reliable improvement in knee function and stability.
    • This method represents a viable alternative for PCL reconstruction.
