Knee Osteoarthritis & Joint Cartilage Wear
Progressive changes in knee articular cartilage, subchondral bone, and synovial joint capsule.
Clinical Overview:
Knee osteoarthritis is a whole-joint condition involving cartilage breakdown, joint space narrowing, mild synovial inflammation, and osteophyte formation, leading to stiffness and load-dependent pain.

03 — What Can It Feel Like?
Common Symptoms
Joint stiffness upon waking, typically easing within 30 minutes of moving
Ache and soreness during weight-bearing activities (stairs, long walks)
Crepitus (grating or crunching sensations) during joint movement
Mild intermittent joint effusion (swelling) after strenuous activity
04 — Movement Consequences
How It Affects Daily Function
Difficulty ascending and descending staircases
Trouble rising from low chairs or getting in/out of vehicles
Hesitancy during longer community walks
05 — Clinical Assessment
What Your Physiotherapist Evaluates
Knee joint range of motion and joint line palpation
Quadriceps and hip abductor strength grading
30-Second Chair Stand test and Timed Up and Go (TUG) functional test
Gait analysis for varus/valgus thrust and knee flexion angles
06 — Treatment Options
Evidence-Informed Rehabilitation
High-compliance progressive quadriceps and gluteal strengthening
Low-impact aerobic conditioning (cycling, aquatic therapy, brisk walking)
Manual therapy for patellofemoral and tibiofemoral mobility
Weight management and biomechanical load optimization
07 — Rehabilitation Journey
*Timelines vary based on tissue biologyPhased Recovery Pathway
STAGE 01Weeks 1–4
Phase 1: Joint Calming & Mobility
Reduce joint irritation, improve knee flexion and extension
Focus: Stationary cycling, gentle range-of-motion drills, isometric quad sets.
STAGE 02Weeks 5–12
Phase 2: Progressive Loading
Build robust muscle mass to absorb joint ground forces
Focus: Leg press, step-ups, glute bridges, and balance retraining.
STAGE 03Ongoing
Phase 3: Lifelong Joint Preservation
Maintain joint health, independence, and delay surgery
Focus: Structured home exercise program and regular active living.
08 — Home Support & Education
Daily Self-Management
Remember: 'Motion is lotion' for arthritic joints—regular low-impact movement lubricates cartilage
Use heat before activity to ease morning stiffness and cold packs after strenuous loading if warm
Wear supportive footwear with cushioned soles
09 — Urgent Safety Guidance
When to Seek Immediate Medical Attention
A hot, red, and severely swollen knee accompanied by systemic fever (rule out septic arthritis)
Sudden complete inability to bear weight with no prior trauma
Severe calf pain and swelling

Frequently Asked Questions
Will exercise wear out my knee cartilage faster?
No. High-quality scientific research proves that appropriate, graduated exercise strengthens the surrounding muscles, improves joint lubrication, and does not accelerate cartilage wear.
