Anatomy & Body Systems
- Origin: Lower pole of patella
- Insertion: Tibial tubercle
- Function: Transmit force from quadriceps to tibia
- Length: Approximately 3-4 cm
- Quadriceps muscle: Primary extensor
- Patella: Sesamoid bone
- Quadriceps tendon: Above patella
- Infrapatellar fat pad: Cushions tendon
- Bursae: Reduce friction
- Quadriceps contracts
- Force transmitted through quadriceps tendon
- Patella acts as lever
- Patellar tendon extends knee
- Critical for jumping, running, kicking
Causes & Root Factors
- Repetitive jumping
- Frequent landing
- Running acceleration/deceleration
- Sudden direction changes
- Excessive training volume
- Sudden increase in training intensity
- Inadequate recovery time
- Poor periodization
- Training on hard surfaces
- Quadriceps tightness
- Hamstring tightness
- Calf muscle tightness
- Patellar tracking abnormalities
- Leg length discrepancy
- Flat feet or high arches
- Inappropriate footwear
- Hard training surfaces
- Cold weather training
Risk Factors
- Age: Peak 15-30 years
- Previous injury: Increases susceptibility
- Flexibility: Tight muscles increase strain
- Strength imbalances: Quadriceps/hamstring ratio
- Biomechanics: Foot and leg alignment
- Genetics: May play a role in tendon quality
- Recovery: Inadequate rest between training
- Equipment: Inappropriate footwear
Signs & Characteristics
- Pain: Localized to patellar tendon
- Location: Below or at kneecap
- Character: Sharp with activity, dull at rest
- Stiffness: Especially in morning or after rest
- Weakness: Difficulty with jumping or stairs
- Pain with jumping, landing
- Pain with stairs (especially down)
- Pain with prolonged sitting (theater sign)
- Pain with kneeling
- Pain improves with rest
- Tenderness on palpation
- Localized swelling
- Thickened tendon
- Pain with resisted knee extension
- Pain with knee flexion against resistance
- Stage 1: Pain only after activity
- Stage 2: Pain during and after, no performance impact
- Stage 3: Pain during and after, performance affected
- Stage 4: Complete tendon rupture
Associated Symptoms
- Chronic pain
- Tendon degeneration
- Reduced athletic performance
- Tendon rupture (if untreated)
- Psychological impact
Differential Diagnosis
- Patellofemoral pain: Different location
- Quadriceps tendinopathy: Above patella
- Osgood-Schlatter: Adolescents, tibial tubercle
- Bursitis: Different location
- Meniscal tear: Different mechanical symptoms
- Rheumatoid arthritis: Multiple joints
- Gout: Acute attacks
- Infection: Different presentation
Conventional Treatments
- Reduce jumping/impact activities
- Cross-train with low-impact activities
- Gradual return to sport
- Ice after activity
- NSAIDs (short-term)
- Topical anti-inflammatories
- Corticosteroid: May provide temporary relief
- Platelet-rich plasma (PRP): May promote healing
- Prolotherapy: Stimulates healing response
- Extracorporeal shockwave therapy (ESWT): May promote healing
- Surgery: For chronic, refractory cases
- Tendon repair: If tear present
Integrative Treatments
- Rhus toxicodendron: For stiffness improving with movement
- Bryonia: For pain worse with any movement
- Arnica montana: For trauma-related symptoms
- Symphytum: Known for tendon healing

- Pain affects daily activities
- Pain affects sports performance
- Swelling is significant
- Stiffness limits function
Red Flags
- Sudden, severe pain
- Inability to bear weight
- Significant swelling
- Locking or giving way
- Signs of infection
Prognosis
- Early stage: 4-6 weeks with proper treatment
- Moderate: 2-3 months
- Chronic: May take 6+ months
- Individual variation expected
Prognosis
- Most improve with conservative treatment
- Eccentric exercise has strong evidence
- Early intervention improves outcomes
- Some require advanced interventions
- Based on symptoms and function
- Gradual return protocol
- Full return may take months
- Recurrence possible
FAQ
What is the best exercise for jumper's knee?
Eccentric squats ( Decline Board Squats) are the gold standard. These should be performed regularly, typically twice daily, with proper technique.
Modify activities rather than stop completely. Low-impact exercises like swimming and cycling are usually fine. Avoid activities that cause pain.
Recovery varies from weeks to several months depending on severity and treatment compliance. Patience is essential.
Most cases improve with conservative treatment. Surgery is reserved for severe, chronic cases that don't respond to 6+ months of proper rehabilitation.
Yes, recurrence is possible, especially if training habits don't change. Ongoing maintenance exercises help prevent recurrence.
No, they are different. Patellar tendinopathy affects the tendon below the kneecap, while patellofemoral pain is around or behind the kneecap.
