Objective:
Transosseous augmentation of patellar sleeve fractures (PSF) with suture tape in young athletes.
Indications:
Acute avulsions of the proximal or distal patellar pol with clinical relevant deficit of knee extension.
Contraindications:
Local infections, severe soft tissue damage (relative contraindication), fractures of the patella or tibial tuberosity.
Surgical Technique:
Direct longitudinal anterior approach to the patella. Debridement of the proximal patellar tendon insertion. Anatomic reduction of any osteochondral fragments. Transosseous augmentation of the tendon with FiberTapes® (Arthrex, Naples, FL, USA).
Postoperative Management:
Passive motion exercise to 30° of flexion from day 1; increase to 60° from week 3; 90° from week 5. Partial load-bearing of 20 kg with knee in locked full extension brace during first 2 weeks. Isometric exercises from week 3. Free active ROM and full weight bearing from week 7.
Results:
If diagnosis and treatment is early and sufficient augmentation of the tendon and periosteum is provided, good to excellent functional outcome can be expected.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
