Stem Cell Therapy
Stem cell therapy involves the injection of stem cells, which are undifferentiated cells that can develop into many different cell types into damaged tissues. The stem cells then differentiate into the required enclosures to heal the tissue.
Stem cells can be obtained from bone marrow, adipose tissue, or donated umbilical cord blood. They are being extensively researched for orthopedic applications such as:
- Treating cartilage injuries and osteoarthritis
- Repairing tendon and ligament tears
- Regenerating bone in fractures, bone defects, and non-unions
- Improving outcomes after orthopedic surgeries
Research indicates that stem cell therapy may reduce inflammation, promote cartilage regeneration, and improve knee function in osteoarthritis patients.
Regenerative medicine therapy doctors are effectively utilizing stem cells for a variety of orthopedic applications. Clinical trials show promising results for stem cell therapy in treating conditions like cartilage injuries, osteoarthritis, and tendon tears.
Platelet-Rich Plasma (PRP) Therapy
PRP involves isolating plasma with a high concentration of platelets from a patient’s blood and injecting it into the injured area. The concentrated platelets release growth factors that stimulate healing.
PRP is being used to treat:
- Tendon and ligament injuries
- Osteoarthritis
- Muscle strains
- Bone injuries
According to a review, PRP reduces pain and improves joint function in knee osteoarthritis. Early results also suggest it may help regenerate cartilage.
Tissue Engineering
Tissue engineering techniques use scaffolds, cells, and biochemical signals to regenerate damaged tissues.
Some orthopedic applications include:
- Bioengineered cartilage for cartilage repair
- Engineered bone grafts for bone regeneration
- Scaffolds seeded with stem cells to heal tendons, ligaments, and cartilage
- 3D bioprinting of musculoskeletal tissues
Research shows bioengineered cartilage scaffolds successfully regenerate hyaline-like cartilage in animal models. Several products are in clinical trials.
Case Studies and Clinical Trials
