Healing II: Complications01:24

Healing II: Complications

Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...

Peripheral Artery Disease V: Postoperative Nursing Management

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
Knee Joint01:23

Knee Joint

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Extensor mechanism complications following total knee arthroplasty (TKA) are infrequent but can lead to severe outcomes.
  • These complications include patellofemoral instability, periprosthetic patellar fractures, and quadriceps tendon or patellar ligament disruptions.

Purpose of the Study:

  • To review the etiology, treatment, and prevention of extensor mechanism complications after TKA.
  • To highlight recent advancements in understanding and managing these adverse events.

Main Methods:

  • Literature review focusing on extensor mechanism complications after TKA.
  • Analysis of etiological factors, surgical techniques, and treatment modalities.

Main Results:

  • The incidence of extensor mechanism complications has decreased due to refined surgical techniques and improved component design.
  • Understanding the specific failure mechanism is crucial for effective treatment, which may involve non-surgical management, primary repair, or reconstruction.

Conclusions:

  • Prevention is paramount, requiring identification of risk factors, meticulous surgical technique, and heightened vigilance.
  • Advances in surgical approaches and component innovation have positively impacted the management and reduced the occurrence of these complications.
