Renewal of Skin Epidermal Stem Cells

Renewal of Skin Epidermal Stem Cells

The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...

Burn Injuries

Burn Injuries

Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Tissue Transplantation

Tissue Transplantation

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.
The Biology of Tissue Transplantation
The biology of tissue transplantation hinges on the Major Histocompatibility Complex (MHC) molecules. These molecules...

Healing II: Complications

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...

Area of Science:

Orthopedic surgery
Sports medicine
Regenerative medicine

Background:

Chronic patellar tendon injuries lead to significant functional deficits, including anterior knee pain and extensor weakness.
Degenerated tissue in chronic injuries necessitates augmentation or reconstruction with grafts.
Achilles tendon allograft is presented as a viable option for reconstruction.

Purpose of the Study:

To describe the technique and outcomes of reconstructing chronic patellar tendon injuries using Achilles tendon allograft.
To evaluate the efficacy of Achilles tendon allograft in restoring function and reducing pain.

Main Methods:

Surgical reconstruction involving excision of the patellar tendon and fixation of an Achilles tendon allograft bone block to the tibial tubercle.
Use of cannulated screws for bone block fixation and Krackow sutures for graft securement.
Quadriceps tendon V-Y advancement was performed for patellar advancement.

Main Results:

Patients achieved near-full range of motion and minimal extensor lag at 1-year follow-up.
Reconstruction significantly improved pain and function compared to preoperative status.
Patients returned to their previous activity levels post-reconstruction.

Conclusions:

Achilles tendon allograft is a suitable option for chronic patellar tendon injury reconstruction.
Advantages include bone-to-bone healing at the tibia, no donor site morbidity, and ample tissue availability.
This technique offers a reliable solution for restoring function in patients with chronic patellar tendon injuries.
