Knee Flashcards
ACL
MOI
Hyperextension, twisting or a combination
Risk Factors
female- greater knee laxity, higher BMI
Male- greater height
poor landing technique: Hip IR and valgus
Subjective:
Weakness/instability
“pop”
Objective
Swelling
gait
Special tests- lachmans, anterior draw, pivot
Meniscal Injury
MOI: twisting
swelling, clicking , joint line tenderness
Mcmurrays test
patellafemoral pain
Umbrella term” -pain in and around the patella also gets called anterior knee pain or
runners knee
Sources of pain - synovial irritation, subchondral bone irritation, lateral retinaculum,
infrapatellar fat pad
-very common
PFPS is common in sport
Patella tracking laterally - causes problems
May sublux
In extreme cases may dislocate laterally
Rx patellar taping VMO & glute med exercises
Patella tendinopathy
Degeneration of the patellar tendon
“Jumper’s knee” - common in basketball, volleyball etc jumping sports
Pain over inferior pole of patella, especially on landing and eccentric loading
Emerging research emphasising the role of exercise (isometrics and decline squats)
as effective therapy for patellar tendinopathy
Flexibility and strength of calf, gluteals, quads also crucial to absorb loads
– Ankle DF
Iliotibial Band Fricton Syndrome
Common in runners and cyclists
Friction / compression between the distal ITB and lateral condyle of femur
Confirm with palpation and Ober’s test for ITB tightness and pain
Glute rehab, stretch
Knee OA
Risk factors Age
– Between age of 50 years and 75 years,
Occupational activities
– Kneeling, squatting, stair climbing, standing, lifting increases risk
Bone mineral density
– Association between increased bone density and knee OA
History of meniscectomy
–
Physical activity
– More active / intense / sport (soccer). Blagojevic et al., 2010; Silverwood et al., 2015
– Recreational runners ↓ occurrence OA. Altentorn-Geli., 2017
