hip pathology Flashcards
pain associated with hip pathology
groin which may radiate to the knee
what nerve supplies the knee and hip joints
obturator
SUFE presents exclusovely with
knee pain
shortening of hipseen in
severe OA, prethes, SUFE or AVN
causes of hip AVN
idiopathic (primary), alcohol abuse, steroids, hyperlipidaemia, thrombophilia
presentation of trochanteric bursitis
patients have pain and tenderness in teh regoin of the greater trochanter with pain on resisted abduction
treatment of trochanteric bursitis
analgeauc, anti inflammatories, physiotherapy
what is trochanteric bursitis also known as
gluteal cuff syndrome
what has the thickest hyaline cartilage in thebody
retropatellar
role of ACL
prevent abnormal internal rotation of the tibia
PCL role
preveenst hyperextension and anterir translation of the femur
MCL resists
valgus force
LCL resists
varus force and abnormal ecternal rotation of the tibia
meniscal injuries caused by
twisting force in a loaded knee
presentation of meniscal injuries
localises pain to the medial or lateral joint line and an effusion develops the following day - locking
how to patients feel if a loose meniscal fragent is caught in the knee
while walking knees may feel like they are about to give way
when do ACL injuries occur
with higher rotational force - turning the upper body on a planted foot
ACL presentation
pop, haemathrosis within an hour, rotatory instability
valgus stress injuries lead to
a tear to the MCL
direct blow to anterior tibia wuth hyoerextension can lead to
PCL rupture
what meniscal tears are more common
medial
what should be considered for meniscal repair
reasonably fresh, longitudinal tears involving the outer 1/3rd of the meniscus in a younger patient
principle complaint of ACL deficiency
instability woth giving way on turning
exaamination of ACL rupture
knee swelling, excessive anterior translation of the tibia on the anterior drawer test and lachman test
PCL rupture presentation
severe laxity and recurrent instability with frequent hyperextension or feeling unstable descending stairs
presentation of patelofemoral dysfunction
patients tend to complain of anterior knee pain getting worse as going down hill and griniding or clicking sensation at the front of the knee and pseudolocking
