Osteoarthritis
Osteoarthritis OA is a degenerative disease of diarthrodial ( synovial ) joints, characterized by Breakdown of articular cartilage and proliferative changes of surrounding bones
Osteoarthritis(OA) is the most common joint disease OA of the knee joint is found in 70% of the population over 60 years of age Radiological evidence of OA can be found in over 90 % of the population
OA may cause functional loss Activites of daily living Most important cause of disability in old age Major indication for joint replacement surgery
OA is a chronic disease of the musculoskeletal system, without systemic involvement OA is mainly a noninflammatory disease of synovial joints No joint ankylosis is observed in the course of the disease
Primary OA Secondary OA Etiology is unknown Etiology is known
Age Sex Obesity Genetics Trauma (daily)
Trauma Previous joint disorders; Congenital hip dislocation Infection: Septic arthritis, Brucella, Tb Inflammatory: RA, AS Metabolic: Gout Hematologic: Hemophilia Endocrine: DM
There are no pathognomonic laboratory findings for OA Laboratory analysis is performed for differential diagnosis
Narrowing of joint space (due to loss of cartilage) Osteophytes Subchondral (paraarticular) sclerosis Bone cysts
G1 Normal G2 Mild G3 Moderate G4 Severe Kellgren Lawrence Classification
CLINICAL FINDINGS Joint pain + RADIOLOGIC FINDINGS Osteophytes
More common in males over 40 years of age Joint stiffness Pain of hip, gluteal and groin areas radiating to the knee Mechanical pain Limited walking function
Hands Feet
Symptomatic treatment Structure modifying treatment Surgical treatment
Regular exercises Weight control Prevention of trauma
Pain relief Preservation and restoration of joint function Education
Patient education Weight loss (if overweight) Aerobic exercise programs Physical therapy Range-of-motion exercises Muscle-strengthening exercises Assistive devices for ambulation Patellar taping Appropriate footwear Lateral-wedged insoles (for genu varum) Bracing Occupational therapy Joint protection and energy conservation
Oral Systemic Medical Agents - Analgesics (acetaminophen) - NSAIDs - Opioid analgesics Intraarticular agents: Hyaluronan Glucocorticoids (effusion) Topical agents
Severe joint pain, resistant to conservative treatment methods Limitation of daily living activities Deformity, angular deviations, instability
Joint lavage Arthroscopy Cartilage grefting- genetic engineering Surgery: Osteotomy Joint replacement
