Summary
Augmenting quadriceps tendon (QT) and patellar tendon (PT) repairs with polyester tapes shows good to excellent outcomes. However, multiple risk factors and high-impact injuries predict poor results and complications.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Trauma Surgery
Background:
- Quadriceps tendon (QT) and patellar tendon (PT) ruptures are infrequent injuries with bimodal incidence.
- Risk factors include renal failure, obesity, steroid/antibiotic use, advanced age, and diabetes.
- Prompt repair is crucial for restoring leg extensor mechanism mobility and preventing morbidity.
Purpose of the Study:
- To evaluate the outcomes of QT/PT rupture repairs augmented with polyester tapes.
- To assess the safety and efficacy of polyester tape augmentation in tendon repair.
Main Methods:
- Retrospective cohort study of patients undergoing polyester tape-augmented QT/PT repair (Jan 2016-Dec 2023).
- Data collection included injury mechanism, risk factors, surgical details, complications, and functional outcomes.
- Operative outcomes (poor, satisfactory, good, excellent) were based on range of motion, weight-bearing, return to fitness, and need for revision.
Main Results:
- 76% of patients (n=69) met inclusion criteria for augmented QT/PT repair.
- 88% achieved good to excellent outcomes; common injury mechanisms were falls and sports-related twisting.
- Multiple risk factors and high-impact injuries significantly predicted poor outcomes and postoperative complications.
Conclusions:
- Polyester tape augmentation of QT/PT repairs is safe and associated with good to excellent outcomes.
- Pre-existing risk factors for tendon rupture also correlate with increased risk of postoperative complications and poorer functional results.

01:27Growth of Cartilage and Bone Tissue
Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...
01:28Phases of Wound Repair
Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.
Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...

01:23Bone as Supporting Connective Tissue
Bone tissue forms the internal skeleton of vertebrate animals, providing structure to the body.
Bone Matrix
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts— mostly calcium salts— that give the...

01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
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 procedure...

01:10Bones of the Lower Limb: Tibia and Fibula
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
