Summary
Restoring joint lubrication is key for osteoarthritis (OA) treatment. This review covers advanced lubricants, including single-function and multifunctional options, to combat cartilage degeneration and pain.
Area of Science:
- Biomaterials Science
- Orthopedics
- Regenerative Medicine
Background:
- Osteoarthritis (OA) is a degenerative joint disease characterized by articular cartilage destruction, leading to pain and reduced joint function.
- Current treatments often focus on symptom management rather than restoring the native lubricating properties of cartilage.
Purpose of the Study:
- To review recent advancements in lubricant-based strategies for osteoarthritis (OA) treatment.
- To explore single-function and multifunctional lubricants, emphasizing their structural features, lubrication properties, and therapeutic potential.
- To discuss challenges and future directions in developing effective joint lubrication therapies for OA.
Main Methods:
- Comprehensive literature review of single-function lubricants (glycosaminoglycans, lubricin, phospholipids).
- Analysis of multifunctional lubricants, including bifunctional hydrogels, stem cell-loaded hydrogels, and drug-loaded nanoparticles.
- Evaluation of lubricants' role in modulating inflammation and metabolism.
Main Results:
- Single-function lubricants offer basic lubrication, while multifunctional lubricants provide enhanced therapeutic effects.
- Lubricating hydrogels and nanoparticles demonstrate potential for combined lubrication, anti-inflammatory action, and drug/cell delivery.
- These advanced lubricants show promise in restoring joint lubrication and addressing OA pathology.
Conclusions:
- Restoring joint lubrication capacity is a critical therapeutic strategy for osteoarthritis.
- Advanced multifunctional lubricants offer promising avenues for OA treatment by combining lubrication with other therapeutic actions.
- Further research is needed to overcome current challenges and translate these innovations into clinical practice.

Joints, also called articulations or articular surfaces, are points at which ligaments or other tissues connect adjacent bones. Joints permit movement and stability, and can be classified based on their structure or function.
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.

00:58Introduction to Joints
2.8K
The adult human body usually has 206 bones, and except for the hyoid bone in the neck, each bone is connected to at least one other bone. Joints are the location where bones come together. Many joints allow for movement between the bones. At these joints, the articulating surfaces of the adjacent bones can move smoothly against each other. However, the bones of other joints may be joined by connective tissue or cartilage. These joints are designed for stability and provide little or no...

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

01:16Structural Joints: Synovial Joints
3.3K
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...

01:23Knee Joint
1.4K
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...

01:20Structural Classification of Joints
3.1K
Joints, also known as articulations, are classified based on their structural characteristics, i.e., based on whether the articulating surfaces of the adjacent bones are directly connected by fibrous connective tissue or cartilage, or whether the articulating surfaces contact each other within a fluid-filled joint cavity. These differences serve to divide the joints of the body into three structural classifications.
