Article Title: Combined Transosseous and Osteosynthetic Reconstruction of Chronic Patellar Tendon Rupture Using Achilles Tendon Allograft With Bone Block

doi: 10.1016/j.eats.2025.103537

Figure Lengend Snippet: (A) With the patient supine and with anterior midline exposure of the right lower extremity, the introduction of the allograft involves placing the “donor” calcaneal bone block into the “recipient” tibial tuberosity trough (arrow 1) and provisionally fixing it in place with two parallel K-wires prior to definitive fixation with cannulated, partially-threaded screws. (B) The graft limb whipstitches are then shuttled through their respective patellar tunnels (arrow 2) using passing sutures. When the patella is reduced, and the native height is confirmed fluoroscopically, the graft limbs are secured using 5.5 mm-biocomposite interference screws (arrow 3) in each patellar tunnel (C). The medial (arrow 4) and lateral (arrow 5) retinacular defects are then closed with No. 2 nonabsorbable ultra-high-molecular-weight polyethylene suture.

Article Title: Multiligament Knee Injury With Common Peroneal Nerve Rupture: Single-Stage Reconstruction of the Anterior Cruciate Ligament, Posterolateral Corner, and Common Peroneal Nerve Graft

doi: 10.1016/j.eats.2025.103445

Figure Lengend Snippet: During posterolateral reconstruction graft passage of the right knee with the patient in the supine position, the bone plug portions of the 2 Achilles tendon allografts are placed into the popliteal tunnel (A) and the LCL tunnel (B) in the femur and fixed using metal interference screws. The LCL graft is passed between the capsule and the iliotibial band and biceps (C) and routed through the fibular tunnel from anterolateral to posteromedial (D). (E) The knee is held at 30° of flexion, with a slight valgus force in neutral rotation, and the graft is fixated in the fibula using a bio composite interference screw. (F-G) The popliteal limb is shuttled intra-articularly and out by the proximal tibiofibular joint and the 2 free ends of the grafts are then shuttled through the tibia from posterior to anterior. (H) With the knee at 60° of flexion and neutral rotation, and slight valgus force, the graft is fixed on the tibia, using a biocomposite interference screw. (LCL, lateral collateral ligament.)

Article Snippet: With the knee at 60° of flexion and neutral rotation, a slight valgus force is applied and the graft is fixed on the tibia, again using a biocomposite interference screw (Arthrex).
