Table 2.
Advantages, Risks, and Limitations of the Presented Technique
| Advantages | Risks and Limitations |
|---|---|
| Anchoring the tendon graft through the retinaculum on either side of the patella avoids a transosseous tunnel, protecting the patella from a potential fracture and the articular cartilage from damage | Unpredictability of graft length and width |
| The U-shaped graft avoids concentration of the tension load over the patella and the repaired patellar tendon | In extensive knee extensor mechanism injury, retinaculum damage may preclude this surgical technique |
| Autologous graft allows biological healing; no synthetic or metallic hardware is needed | Risk of tibial tubercle fracture during tunnel drilling |
| The U-shaped graft fixation avoids overtightening or undertightening and consequent patella alta or baja |
