Pes Anserinus Bursitis Flashcards
1
Q
Pes Anserinus Definition
A
- Common cause of medial knee pain
- Inflammatory condition of the conjoined insertion of sartorius, gracilis, and semitendinosus
- Located right below the medial knee joint
2
Q
Pes Anserinus Causes
A
- Repetitive overuse (flexion and adduction) causing friction and increased pressure
- Sports involving high amount of lateral movements
- Direct trauma — contusion
- Hamstring tightness
3
Q
Pes Anserinus Patient Profile
A
- Obese, middle-aged women with knee OA
- Risk factors — knee OA and flat feet cause more pressure on medial knee
4
Q
Pes Anserinus Clinical Presentation
A
- Pain around anteromedial proximal knee
- Pain and tenderness
- Pain worse with climbing stairs or sit to stands
- Crepitus can be present
- Pain reproduced with palpation — to differentiate between meniscal tear
- Swelling
- Others — decreased muscle strength, gait deviations, decreased function, decreased ROM, postural dysfunction, impaired LE biomechanics
- Irritation caused by flexion, adduction, rotation, pivoting, kicking, squatting, or quick movements from side to side
5
Q
Pes Anserinus Diagnosis / Examination
A
- Clinical evaluation
- X-ray to r/o fracture, arthritis, or osteocondritis dissecans (bone beneath cartilage dies due to lack of blood flow, most common in knee, most common in children and adolescents in sports with repetitive stress on joints)
- Examination — palpation and passive hamstring length test 90-90 in supine
6
Q
Pes Anserinus Management
A
- Initial Tx — ice, rest, NSAIDs, ice massage, rest (avoid stairs and aggravating activities)
- Corticosteroid injections
- Surgery with failure of conservative treatment
- Stretching (hamstrings, calf, quad, hip add)
- Heel slides, quad isometrics, hamstring isometrics
- Strengthening of LE (quads, hamstrings, add, and abd)
- Progression of closed chain exercises (single knee dips, squats, leg pressed)
- Ultrasound
- KT tape
