1 OSTEOARTHRITIS (OA) Rogelio A Balagat MD ASMPH

2 Assignment: 1. Age 2. Weight & height (BMI) 3. Joint pain (VAS) 4. Joint deformity

3 Definition of OA Joint failure failure of protective mechanisms cartilage loss subchondral bone changes osteophytes capsule stretching mild synovitis periarticular muscle weakness

4 JOINT INJURY JOINT REPAIR -OA +OA FAILURE OF PROTECTIVE MECHANISMS WEIGHT-BEARING

5 Main joint protector Cartilage Avascular Aneural Load-bearing Low friction

6 Joint protectors Joint fluid lubrication Muscle-skin sensory afferent nerve mechanoreceptors Muscle-tendon co-contraction Subchondral bone shock-absorption

13 PRIMARY OA aging bone & cartilage mechanical factors accumulated microtrauma lower limb malalignment genetic factors

14 SECONDARY OA mechanical joint incongruity congenital, genetic, developmental disorders prior joint trauma/surgery prior inflammatory joint disease bleeding dyscrasia neuropathic joint disease excessive intra-articular steroid injections endocrinopathies & metabolic disorders acromegaly Cushings disease gout/pseudogout

15 Chronic >40, F>M, weight Non-inflammatory DIP, CMC1, Knee, Hip Use-related pain onset of movement after activity improved with rest

16 Bouchards nodes (PIP) Heberdens nodes (DIP) squared-off base of thumb malalignment swelling crepitus KNEE OA HAND OA

17 HIP OA pain in groin or inner thigh antalgic gait, limited/loss of flexion, extension, rotation predisposing conditions congenital hip dysplasia, avascular necrosis

18 SPINE OA apophyseal joints, disc/vertebral bodies (spondylosis) paraspinal pain, spasm radicular symptoms cervical neck pain, radiates to shoulder, upper back, distal arm weakness, paresthesias of hand, arm

19 SPINE OA lumbar low back pain, radiates to buttocks, legs, feet cauda equina syndrome neurogenic claudication cord compression- leg weakness; gait, balance problems mechanical compression of vital structures- dysphagia, cough, headache, vertigo

20 Radiography Bone formation (-) bone erosion

21 DIFFERENTIAL DIAGNOSIS Rheumatoid Arthritis Monoarticular Polyarticular Spondyloarthropathies Psoriatic arthritis Reactive arthritis Inflammatory bowel disease Ankylosing spondylitis

22 DIFFERENTIAL DIAGNOSIS Crystal-induced arthritis Gout Other disorders infectious arthritis periarticular tendenitis or bursitis Rare neoplastic synovitis pigmented villonodular synovitis neoplastic metastasis to juxta-articular bone

23 PHARMACOLOGICNON PHARMACOLOGIC SURGICAL INTERVENTION Considered as the CORNERSTONE in the Management of OA Considered as ADJUNCTS to Non-pharmacologic Management

24 NON PHARMACOLOGIC Psychosocial Interventions Patient Education Physical Modalities Thermal Modalities Exercise Supportive Devices Modifications in ADL Psychosocial Measures PHARMACOLOGIC Topical Agents Intra-articular Agents Oral (Systemic) Agents Symptom Modifiers Potential Disease Modifiers
