Summary
Synovial fluid glucose and lactate levels can indicate osteonecrosis of the femoral head. These metabolites may help monitor the effectiveness of revascularization treatments in canine models.
Area of Science:
- Orthopedics
- Biochemistry
- Regenerative Medicine
Background:
- Osteonecrosis of the femoral head involves bone cell death due to interrupted blood supply.
- Monitoring treatment response for femoral head osteonecrosis requires effective biomarkers.
Purpose of the Study:
- To assess synovial fluid glucose and lactate as biomarkers for osteonecrosis.
- To evaluate these metabolites in a canine model of femoral head osteonecrosis.
Main Methods:
- Osteonecrosis was surgically induced in canine femoral heads.
- Treatment groups included no intervention, vascular endothelial growth factor (VEGF), vascularized bone graft, combined VEGF and graft, and alendronate.
- Synovial fluid was analyzed for glucose and lactate concentrations after 12 weeks.
Main Results:
- Osteonecrotic joints showed decreased glucose and increased lactate in synovial fluid compared to controls.
- VEGF, vascularized graft, or combined treatments normalized these metabolite levels.
- Alendronate treatment did not restore normal synovial fluid metabolite concentrations.
Conclusions:
- Synovial fluid glucose and lactate alterations reflect anaerobic metabolism in osteonecrosis.
- These metabolites show potential as biomarkers for monitoring revascularization therapies.

Glycosaminoglycans
Glycosaminoglycans (GAGs), also known as mucopolysaccharides, are long and linear polymers comprising of specific repeating disaccharides - the amino sugar that can be N-acetylglucosamine or N-acetylgalactosamine, and a uronic acid that is usually glucuronic acid or iduronic acid.
GAGS are found in the extracellular matrix of vertebrates, invertebrates, and bacteria. Due to their polar nature they attract water, and serve as excellent lubricants or shock absorbers in an animal body.

Osteoclasts in Bone Remodeling
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
Structural Joints: Synovial Joints
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...
