Insights

Osteoarthritis (OA) is a complex disease with varied patient responses. Stratifying OA patients into distinct subsets is crucial for developing targeted treatments and improving therapeutic outcomes.

Area of Science:

  • Rheumatology and Orthopedics
  • Translational Medicine

Background:

  • Osteoarthritis (OA) presents as a heterogeneous condition with diverse clinical manifestations, genetic profiles, and treatment responses.
  • Current OA treatments often lack efficacy due to this variability, necessitating personalized therapeutic strategies.

Purpose of the Study:

  • To review existing literature on clinical and physiological variability in osteoarthritis.
  • To explore the potential for stratifying osteoarthritis patients into distinct subgroups for tailored interventions.

Main Methods:

  • Systematic review of current literature on osteoarthritis heterogeneity.
  • Analysis of reported stratification methods based on clinical and physiological variables.

Main Results:

  • Several stratification approaches have been identified, including disease onset, progression stage, joint involvement, inflammation, and effusion.
  • These methods commonly reveal two to three distinct osteoarthritis subsets.
  • Stratification variables can be transient or consistent throughout the disease course.

Conclusions:

  • Patient stratification holds significant promise for optimizing current osteoarthritis treatments.
  • Further research into stratification techniques is essential for developing effective, disease-modifying interventions for specific OA subgroups.

Functional Classification of Joints01:09

Functional Classification of Joints

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.

An immobile...
Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Classification of Bones01:18

Classification of Bones

The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The long...
Classification of Connective Tissues01:30

Classification of Connective Tissues

The connective tissues have different properties and functions in the human body. They are broadly categorized into proper, supporting, or fluid connective tissues.
Connective Tissue Proper
Connective tissue proper is the most abundant class of connective tissues. As its name implies, it predominantly connects different tissues in the body. Depending on the cell types, ground substance, viscosity, and fiber types in the ECM, connective tissue proper is further categorized into loose and dense.
Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...
Classification of Illness01:17

Classification of Illness

The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe and...
