Peripatellar pain• Common causes

• Patellar dislocation or subluxation• Patellar tendinitis• Osgood-Schlatter’s disease• Sinding-Larsen-Johansson disease• ITB friction syndrome• Bursitis• Osteoarthritis• Patellar fracture• Quadriceps strain• Gaut• Etc.

Anterior Knee Pain• Patellofemoral pain syndrome

• Patellofemoral joint syndrome

• Jumper’s knee

• Chondromalacia patellae

• Peripatellar synovitis

Patellofemoral Pain Syndrome• Anterior knee pain• Most common cause in young population• Young female atheletes• Gradual onset

• Aggravated at• Squat• Stair up/down• Sit to stand• Knee flexion

5

PFPS• Sympoms

• Feeling of instability• Localized pain• Crepitus• Edema• Feeling of muscle weakness

• Cannot squat• Cannot stair up/down

05/01/2023

6

PFPS• Pain sources

• Peripatellar synovitis without obvious cartilage damage

• Soft tissues such as lateral retinaculum• Infrapatellar fat pad

• Self limited conditions• No disability• Benign neglect

05/01/2023

7

Pathophysiology • Increased tension of patella to lateral side due to

• Overpronation of foot• Increased Q-angle• VMO weakness• Muscle power imbalance

Physical Exam• Palpation

• Localized edema/tenderness

• Patellar glide test• Lateral glide, more than 50%

• Patellar tilt test• Lateral tilt, less than 0 degree

Treatment • Reduction pain & inflammation

• Ice, NSAIDs, ultrasound, ultrasound, mobilization

• Address extrinsic contributing factors• Reduce excessive load to patellofemoral joint

• Address intrinsic contributing factors• Remote factors: hip muscle retraining, flexibility, foot or-

thoses• Local factors: patellar taping, bracing, Q-ceps strength-

ening

18

Orthoses• Reduction of foot over-pronation• Reduction of Q-angle

• Insoles/foot orthoses

• Limited evidences

Pharmacological Treatment• Intra-articular glycosaminoglycan

• NSAIDs, Aspirin

• Corticosteroid

• Botulinum Toxin?

• Surgery – arthroscopic lateral release

Take Home!• Patellofemoral Pain Syndrome

• Common cause of anterior knee pain

• Biomechanical problems of patella

• Exercise – VMO retraining

• Only Naproxen (VIMOVO) has evidence
