Study Notes
Meniscus Tears
- Types of tears: flap tear, bucket handle tear
- Flap tear: circumferential tearing with radial lines, creating a meniscal flap that can cause transient pain
- Bucket handle tear: large vertical tear that breaks away from the meniscus, losing structural integrity
- Causes: excessive rotation, especially in closed chain; more likely to occur in areas with innervation and vascularization
- Symptoms: vague pain, medial or lateral, risk factors include women, kneeling, bending, and stair climbing
- Examination: pain to palpation, functional motion, McMurray's, Ege's, Thessaly's, Apley's, Steinmann I and II, and Bounce Home tests
- Treatment: avoid closed chain rotation, ice, joint mobilization, meniscofemoral and meniscotibial mobilization, and progressive ROM and weight-bearing exercises
Anatomy of Meniscus
- Wedge-shaped structure covering the tibial articular surface
- Fiber types: meshwork, lamellar, circumferential, and radial "tie" fibers
- Meniscal tear patterns: follow circumferential or radial directions of the deepest layer
ACL Injury
- Mechanism of injury: non-contact, rapid deceleration, tibial anterior shear, valgus, and tibial internal rotation
- Risk factors: fatigue, generalized laxity, poor hip control, excessive pronation, and turf conditions
- Symptoms: audible pop, immediate swelling, pain, and difficulty walking
- Examination: pain with most knee movements, decreased ROM, and positive Anterior drawer and/or Lachman's test
- Treatment: patient education, manual therapy, and progressive rehabilitation protocols
PCL Injury
- Mechanism of injury: high-energy trauma, dashboard MVA, fall on a flexed knee, and forced hyperextension
- Symptoms: deep, diffuse pain surrounding the knee
- Treatment: isolated injuries may be treated non-operatively, but concomitant injuries often require surgery
Collateral Ligament Injuries
- Mechanism of injury: valgus stress, varus stress, and excessive lateral rotation
- MCL injuries: most common, particularly among athletes, and classified based on location within the knee joint
- LCL injuries: less common, but can occur during varus stress or excessive external rotation
- Grading of tears: Grade I (mild strain), Grade II (partial tear), and Grade III (complete rupture)
- Symptoms: localized pain, antalgic gait, and pain to palpation
- Treatment: activity modification, ice, crutch training, orthotics, and progressive rehabilitation protocols
Knee Osteoarthritis
-
Pathogenesis: initiation of load alteration, disruption of cartilage, upregulation of catabolic factors, and loss of proteoglycans
-
Progression: increased knee adduction moment, medial compartment collapse, and lateral compartment distraction
-
Risk factors: hip weakness, weight gain, or instability, ACL deficiency or laxity, and prior knee injury
-
Treatment: progressive rehabilitation protocols, weight management, and hip strengthening exercises### Knee Pain Syndromes
-
Patellofemoral Pain Syndrome: Localized anterior knee pain, primarily affecting females, especially those under 50, and athletes.
- Risk factors: Running/jumping sports, repetitive knee extension, and heavy BMI.
- Characteristics: Retropatellar pain, extensor mechanism dysfunction, and chondromalacia.
- Mechanism of injury: Compression, quadriceps/ITB tightness, and unstable tracking.
- Treatment: Manual therapy, therapeutic exercise, and patient education.
Patellar Tendinopathy
-
Jumper's Knee: Localized pain at the proximal patellar ligament, typically affecting 35-50-year-olds.
- Risk factors: Repetitive movements, heavy body mass, and increasing tendon load.
- Characteristics: Swelling, pain with palpation/contraction, and tissue changes.
- Mechanism of injury: Rapid increase in knee extension, tendon separation, and neural ingrowth.
- Treatment: Activity reduction, ice, orthotics, patellar tendon strap, and strengthening exercises.
Tibial Tubercle Apophysitis
-
Osgood-Schlatter Disease: Localized pain at the tibial tubercle, typically affecting 8-15-year-old boys.
- Risk factors: Rapid bone growth, excessive force, and poor muscle control.
- Characteristics: Focal swelling, pain with stair climbing, squatting, and running.
- Mechanism of injury: Irritation of the apophysis due to rapid bone growth.
- Treatment: Strategic rest, ice, manual therapy, and strengthening exercises.
Osteoarthritis
-
Osteoarthritis (OA): Diffuse knee pain, primarily affecting individuals over 45, especially women, and those with a prior knee trauma.
- Risk factors: Age, obesity, and genetic susceptibility.
- Characteristics: Deep aching pain, antalgic gait, bony enlargement, and varus deformity.
- Mechanism of injury: Joint degeneration and surface changes.
- Treatment: Patient education, modalities, compression, and strengthening exercises.
Meniscus Injury
-
Meniscus Tear: Pain, swelling, and stiffness in the knee, typically affecting the medial or lateral joint line.
- Risk factors: Trauma, sports, and age.
- Characteristics: Pain with twisting, bending, or squatting.
- Mechanism of injury: Tears in the meniscus cartilage.
- Treatment: Dependent on the severity and location of the tear.
ACL and PCL Injuries
-
ACL and PCL Injuries: Pain, instability, and swelling in the knee, typically affecting athletes.
- Risk factors: Trauma, sports, and age.
- Characteristics: Pain with twisting, bending, or pivoting.
- Mechanism of injury: Tears in the anterior or posterior cruciate ligaments.
- Treatment: Dependent on the severity and location of the tear.
Collateral Ligament Injuries
-
MCL and LCL Injuries: Pain, instability, and swelling in the knee, typically affecting athletes.
- Risk factors: Trauma, sports, and age.
- Characteristics: Pain with twisting, bending, or pivoting.
- Mechanism of injury: Tears in the medial or lateral collateral ligaments.
- Treatment: Dependent on the severity and location of the tear.
