Q

MTU- functions as a shock absorber and spring- bad

A

poor muscle coordination (ineffective function)- reduced energy efficiency and greater amplitude of tendon strain or greater cumulative load- greater energy absorption (More heat)- potential to trigger cellular response and tendinopathy

Q

collateral ligament injury- mechanisms of injury

A

usually varus/valgus contract force (i.e.direct blow to the knee can also occur as a result of a varus or valgus blow to the foot, MCl most commonly injured structure in knee> common than LCL, characteristic instability caused by MCL/ LCL injury is opening of medial/lateral joint space

21
Q

signs and symptoms of lig injury

A

any age group but often early adulthood, focal joint pain, +/- h/o clicking/ popping, giving way, locking, swelling developing (24+ hours for extra articular lig, <24 for intra articular), positive test

22
Q

ACL- MOI

A

injury on external rotation, usually sudden deceleration and change of direction with fixed foot or hyperextension injury, often combined with valgus strain of MCL and medial meniscus

23
Q

ACL- signs and symptoms

A

knee buckles, unable to stand, immediate swelling- haemarthrosis (within 2 hours), inability to resume sport, locking/ loss of extension, positive lachmans test

24
Q

PCL- MOI and S+S

A

MOI- posterior force to proximal tibia, if combined with rotational force injury to P-L complex
S+S= mild to mod swelling, positive posterior draw test, often asymptomatic, pain on kneeling

25
postero-lateral complex- structures involved
ITB/LCL/Popliteus/acurate ligament/ posterior horn lat meniscus/ lat coronary ligament/ posterior lat joint capsule/ bicep fem tendon
26
postero-lateral complex- injury
rare but disabling and need specialist referral, associated with ACL/PCL injuries, poor outcome
27
postero-lateral complex- mechanisms
direct blow to antero-medial tibia in an extended knee, fall onto a flexed knee, non-contact hyperextension
28
S +S of postero-lat injury
pain in the postero-lateral corner, personal nerve symptoms, associated ligament pathology, positive posterolateral drawer
29
S + S of meniscal tears
H/O loaded twisting/ squatting, catching, locking, acute block to extension, effusion developing over 24 hours, joint line tenderness, +ve clinical tests= McMurray's/ Apley's/ Joint line tenderness
30
Patella-femoral disorders
patella femoral pain syndrome, Mal-tracking, dislocation, chondromalacia patella, patella tendinosis, prepatellar bursitis
31
PFPS
pain at front of knee, worsened by prolonged sitting/ stair climbing or activities involved in bending, usually related to excessive mechanical loading/ chemical irritation of nerve endings
32
PFPS- contributing factor
patella malalignment- abnormal biomechanics, muscle imbalance, overuse, direct trauma
33
P/F dislocation / subluxation
dislocation- patella slipped out and had to be manually relocated, subluxation- patella slipped out and spontaneously relocated S+S= localised tenderness around medial extensor retinaculum+ lateral knee pain, haemarthrosis,
34
PFJ disorders- functional and structural
functional- muscle length/ strength, stability, proprioception structural- bony alignment, patella shape, trochlear shae, foot position
35
PFD treatment
pain/CMP/maltracking- patella mobilisation/ tape/ exercise | dislocation- reduction, tendon transposition, quadriceps strengthening
36
meniscal management- depends on
clinical evaluation, associated lesions, type/location and extent of tear
37
meniscal management- arthroscopic management
partial meniscectomy- preserve peripheral rim+ remove loose unstable fragment= increases incidence of degenerative changes, meniscal repair= poor success, rehab programme- depending on surgery
38
meniscal management- conservative treatment
10% of patients with partial thick or short radial tears requires surgery after 4 years, mobilisations, exercise- quads and proprioception
39
ligament rehab
unlikely to be isolated, consider Rx of other structures, rehab +/- reconstruction, functional bracing MCL- aggressive conservative rehab 4-6 weeks return to sport, PCL or LCL= if isolated (unusual) then conservative, not isolated= surgery
40
lateral ligament strain diagnosis- demographic and 24hr aggs
demographic- common teens to 40's | 24 hr: Aggs- walking or running over uneven ground, turning sharply, landing on inverted ankle
41
lateral ligament strain diagnosis- symptoms and HPC
symptoms- pain+SWELLING local esp. ATFL | HPC- traumatic= specific injury involving ankle inversion, sudden onset, can be recurrent
42
lateral ligament strain diagnosis- SQ and SH and assessment
SQ- giving way, swelling- onset or recurrent, walking over uneven ground SH- sport involving rotation assessment= ROM, lig tests, muscle strength tests, rehab target deficits
43
lateral ligament strain diagnosis- management (functional vs Immobilisation)
``` functional treatment (ankle exercises + external support) and proprioception immobilisation= more effective in shor and long term than immobilisation (decreased swelling, increased stability) ```
44
plantar fasciitis- demographic and 24 hour aggs
demo- late 50's, obese women, athletes (long distance runnings) 24 hour= first few steps am, or after prolonged rest, running/dancing/jumping/prolonged standing/walking
45
plantar fasciitis- subjective
symptom location- medial origin of medial band of plantar fascia, HPC- gradual onset over weeks/months, may be associated with traumatic incident FSH- sport or job that involves weight bearing SQ= P+Ns or Numbness
46
plantar fasciitis- management- taping
medial arch support for the overpronated foot, correction of calcaneal valgus, effectiveness unknown,
47
plantar fasciitis- management exericses
stretching of PF, hamstrings and calfs= improved with stretching alone, strengthening of tibialis posterior, intrinsics may be beneficial but lack of evidence
48
perthes
AVN of femoral head, self limiting with revascularization occurring within 2-4 years, femoral head may remain deformed resulting in OA, most common in 6 year old males, want to reduce weight bearing and see if femoral head regrows
49
LL disorder treatments
tendons= modify load, strengthen, progress, RTP joint/OA- modify load/ ROM/ Strengthen/ progressive function ligaments= modify load/ ROM/ balance/ strength/ neuromuscular control fractures and joint replacement- ROM/ strengthen/ rehab function
50
what do locking, swelling, subjective assessment at knee
locking= meniscus injury (tear can lead to flaps that can catch), swelling- constant? temp, how long? activity induced? knee giving away/locking- how many times over a period of time? painful?
51
what is the unhappy triad an dhow to differentiate between them?
meniscus, ACL, LCL | meniscus= locking, ACL- giving way/ popping/ immediate swelling, MCL- pain and swelling medially
52
test for PFJ pain
stairs and squats- anything where flex and ext under load
