Q

Myositis Ossificans

A

Development of bone in muscle due to calcification during inflam. process; Develops from blood pooling close to bone; Start massaging quickly to push blood away from area of injury

25
MCL Sprain - Mechanism
Mechanism = DIRECT BLOW TO LAT SIDE OF LEG; QUICK CHANGE OF DIRECTION; IR of femur; ER of tibia;
26
MCL Sprain - S/Sx
S/Sx = Pain at MCL; hemarthrosis; decreased RoM; (+) Valgus stress test; Med meniscus and capsule may also be injured
27
LCL Sprain - Mechanism
Mechanism = IMPROPER LANDING from a jump; DIRECT BLOW TO MEDIAL SIDE OF LEG; IR of tibia; ER of femur;
28
LCL Sprain - S/Sx
S/Sx = Pain at LCL; minimal edema because it is outside of the capsule; (+) Varus stress test
29
ACL Sprain - Mechanism
Mechanism = RAPID DECELERATION COMBINED WITH IR; Hyperextension; POSTERIOR BLOW TO TIBIA (such as at dog parks); Anterior blow to femur;
30
ACL Sprain - S/Sx
S/Sx = Sharp pain, audible pop, then fall; Sensation that "whole knee just moved"; (+) Anterior drawer test; (+) Lachman's test
31
PCL Sprain - Mechanism
Less common than ACL sprains; Mechanism = MVAs; POSTERIOR BLOW TO FEMUR; Anterior blow to tibia; HYPERFLEXION; Severe Hyperextension (ACL then PCL);
32
PCL Sprain - S/Sx
S/Sx = Sharp pain, audible pop, then fall; (+) Posterior drawer test
33
Patellar Tendon Rupture - Mechanism
Mechanism = Forceful contraction of quads (knee extension); Jumping up
34
Patellar Tendon Rupture - S/Sx
S/Sx = Indentation below patella where tendon was; bruising; tenderness; cramping; Patella alta; inability to straighten knee; difficulty walking due to knee buckling or giving way
35
Patellar Tendonitis - Mechanism
Inflammation of patellar tendon; Mechanism = overuse
36
Patellar Tendonitis - S/Sx
S/Sx = Pain, edema, crepitus; tender at inf. Pole of patella
37
Meniscus Sprain - Mechanism
Medial more common than lateral; Mechanism = weight-bearing with rotational stress
38
Meniscus Sprain - S/Sx
S/Sx = Joint line pain, snapping following injury; posterior pain possible; clicking; locking of knee; mild edema day after injury
39
Medial Meniscus Sprain - Mechanism
Mechanism = Weight-bearing with external rotation stress
40
Lateral Mensiscus Sprain - Mechanism
Mechanism = Weight-bearing with internal rotation stress
41
Unhappy Triad
ACL sprain, MCL sprain, & Medial Meniscus Sprain
42
Unhappy Triad - Mechanism
Mechanism = Valgus stress with ER; Direct blow during rotational movement; CUTTING WHILE RUNNING
43
Patellar Fracture - Mechanism
Mechanism = Direct trauma, fall
44
Patellar Fracture - S/Sx
S/Sx = Pain, edema, radiating pain, indirect tenderness; HARD TO DIAGNOSE on Xray
45
Pes Anserine Bursitis
Chronic inflammation of bursa; Gracilis - add; Sartorius - Ext; Semitendinosis - fles
46
Pes Anserine Bursitis - Mechanism
Mechanism = Cyclist's Knee; overuse
47
Osgood Schlatter's Disease - Mechanism
Mechanism = Direct trauma to tibial tuberosity & then over use; COMMON IN TEENAGERS ACTIVE IN SPORTS
48
Osgood Schlatter's Disease - S/Sx
S/Sx = Large bump on tibial tuberosity; tender to palpation; No pain w/ activity
49
Osgood Schlatter's Disease - Complication
Complication = Avulsion (rupture) of tendon from bone; usually happens with rapid growth spurts
50
Osgood Schlatter's Disease - Tx Recommendation
Treatement Recommendation = Should be removed from activity to prevent further damage
51
Patello-femoral Syndrome
Chondromalacia - softening of underneath surface of patella & anterior surface of femur
52
Patello-femoral Syndrome - Mechanism
Mechanism = Overuse
53
Patello-femoral Syndrome - S/Sx
S/Sx = lateral tracking of patella in fossa; Abnormal Q angle - more common in women; pain w/activity, edema, crepitus; stiffness w/ extended sitting (Movie goers knee); AM stiffness; pain with palpation along medial border of knee
54
Osteoarthritis
Chronic disorder; narrowing of joint space
55
Osteoarthritis - S/Sx
S/Sx = Medial pain; stiffness; decreased RoM; Edema
56
Prepatellar Bursitis - Mechanism
Housewife's Knee; Mechanism = extended kneeling; direct blow to knee; overuse
57
Prepatellar Bursitis - S/Sx
S/Sx = Marked local edema; pain on extreme flexion due to pressure on bursa
58
Popliteal Bursitis
Baker's Cyst; affects medial hamstring tendons due to irritation
59
Popliteal Bursitis - Mechanism
Mechanism = overuse
60
Patellar Dislocation - Mechanism
Mechanism = Sudden change of direction while weight-bearing; direct trauma
61
Patellar Dislocation - S/Sx
S/Sx = Pain, edema, deformity; Will often sublux and return to original position
