Exam 2 Flashcards
(29 cards)
what foot deformity is most common with patellofemoral pain?
forefoot varus
AKPS
- anterior knee pain scale
- outcome measure
- 100 max points (no pain)
patellofemoral pain often seen in:
runners
patellar tendinopathy often seen in:
jumping athletes
patellofemoral dislocation most common in:
adolescent age group during athletic activity
symptoms associated with patellofemoral pain syndrome:
- pain using stairs, running
- no trauma
- pain with prolonged sitting with knee flexed, relieved by extending knee
- anterior knee ache relieved by rest from aggravating activities
- anterior knee pain elicited during a squatting maneuver
symptoms of neuropathy of infrapatellar branch of saphenous nerve:
- could be injured during surgery, or from direct trauma
- nerve sensitive to palpation, and neuropathic pain “burning, tingling”
- allodynia
- can result in severe symptoms
- limited flexion
Ottowa Knee Rules
- age 55 or older
- isolated tenderness of the patella (no bone tenderness of knee other than patella)
- tenderness of head of fibula
- inability to flex to 90 degrees
- inability to bear weight both immediately and in the clinic for 4 steps
Red Flag for DVT
- pain or tenderness
- swelling, warmth, redness, discoloration
- distention of surface veins
Wells Score categorization
- high if greater than 2
- moderate if 1 or 2
- low if less than 1
symptoms of septic arthritis
- history of recent infections, recent surgery or joint infection, presence of prosthesis
- symptoms: constant throbbing, aching pain in joint even at rest, swelling and warmth
- may have systemic symptoms such as fever and chills, fatigue
- knee and hip most commonly affected
signs of osteochondral defect
- history of trauma involving rotation while knee is loading, landing from a jump
- pain with weight bearing
- locking
- crepitus
- pain and swelling after activity
- eased after unloading joint
osteochondritis dissecans most often develops in:
children and adolescents
contact area between patella and trochlea gradually increases as:
knee flexes
for rehabbing articular cartilage injuries, OKC ROM for exercise should be:
90-45 degrees
for articular cartilage injuries, CKC ROM for exercise progression:
initially: 0-30
as heals: 0-60
then 0-90
osteoarthritis risk factors
- increasing age
- obesity
- genetic predisposition
- inappropriate loading
rehab after partial menisectomy:
- WBAT immediately and progress to FWB
- restore full AROM ASAP, get quads firing immediately
- progress activity slowly according to pain, and swelling
- can return to full activity 2-4 weeks
rehab after meniscus repair
- WB restricted for 2-4 weeks
- ROM 0-90; not hamstring activity if medial meniscus
- start with iso quads immediately; progress after 4-6 weeks to knee ext PRE
- usually start functional training at 3 months and return to full around 6 months
If knee opens at 30 and 0 degrees during valgus stress test:
- then other ligaments are involved such as the ACL or PCL
- need to be referred for imaging
what percentage of ACL injuries are non-contact?
80%
recurrence (same side or opposite side) after ACL reconstruction?
29%
ACL graft strength timeline:
- strongest when first go in
- weaken over first 6-12 weeks
- gets stronger as revascularize (16 weeks)
- Maturation can take 12-18 months (still usually only 50% as strong as normal ACL)
knee posterolateral ligaments:
- LCL
- popliteus muscle-tendon ligament unit (includes popliteofibular ligament and posterolateral capsule)
