Knee- Patellar Dislocation thru Functional Testing Flashcards
What is the worse case of PFPS?
Patellar dislocation
What is the incidence of patellar dislocation?
rare
What are risk factors for patellar dislocation?
- pre-existing patellar hypermobility
What makes patellar dislocation more common?
- shallow sulcus angle
- congruence angle lateral to zero line or laterally located patella
What is the etiology of patellar dislocation?
- trauma with lateral patella displacement
- may be more likely with pre-existing patellar hypermobility
What are the structures involved with patellar dislocation?
- patella
- med retinaculum and other medial tissues
What are S&S of patellar dislocation?
- worse case of PFPS hypermobility
- patellar apprehension likely to be positive
What is the PT rx for patellar dislocation?
- non- WB to PWB up to 3 weeks
- immobilizer
- POLICED
- MET
What do we need the immobilizer for with patellar dislocations? (DONT MEMORIZE RN, REFERENCE)
- possibly allowing up to 60 degrees flexion for 3 weeks
- flexion progressed to 90 degrees until 6 weeks
When should we have full ROM with patellar dislocation?
- full ROM after 6 weeks
- < 6 weeks leads to higher dislocation rates
What can taping do for patellar dislocation?
- protection
- allowed 30-40 degrees flexion for 5-6 weeks
- apply after 1 week immobilization
- better outcomes than complete immobilization
When should muscular control be used with patellar dislocation?
at least up to 6 weeks
What can we use a brace for with patellar dislocation?
patellar control
What kind of exercises should we start with for MET?
CKC exercises prior to OCK
What should we do for the quads with MET for patellar dislocation?
- isometrics and isotonics
What structures should we work on extensibility and elasticity with?
- postlat structures
- hams
- IT band
- Gastroc
What is the prognosis with patellar dislocation?
- up to a 44% re-dislocation rate
- higher without sx
What is IT band syndrome?
- basically a tendinopathy of the distal IT band
What is the prevalence of IT band syndrome?
- 5-14% of runners
- 2nd leading cause of knee pain in runner
- biological males are 50-81% of cases
What are risk factors for IT band syndrome?
- running
- training errors
- weak hip ERs and Abd
- excessive pronation
- increased hip add and IR
- trunk lean in U stance
What is IT band syndrome associated with? (other conditions)
- GTPS
- PFPS
- recognize common contribution
What is the etiology of IT band syndrome?
- little is known that leads to abnormal mechanical loading
- consider lumber hypermobiity/instability with impaired LE control and excessive recruitment of TFL as a hip flexor
What are the structures involved with IT band syndrome?
-TFL/IT band
- Lateral femoral epicondyle, Gerdy’s tubercle (insertion) and associated bursae and fat pad
What are the pathomechanics of IT band syndrome?
- tendinopathy origins
What are the symtoms of IT band syndrome?
- gradual onset of lateral knee pain
- worse with activities involving repetitive knee motion, hills, and dynamic U stance such as running
What will we observe with IT band syndrome?
- impaired LE control
- possibly thickened tendon
What will we find with ROM with IT band syndrome?
pain likely with hip adduction and knee fleixon
What will we find with resisted testing/MMT withIT band syndrome?
- possible hip ER weakness
- possible hip abd weakness with pain, particularly in a lengthened position
- possible pain and weakness with knee ext
What will we find with special tests with IT band syndrome?
- possible positive Ober’s
What will we find with palpation with IT band syndrome?
- TTP over lateral femoral condyle and Gerdy’s tubercle
What can we educate the patient on with IT band syndrome?
- soreness rule (MILD pain okay 24-48 hours out)
- load management (active rest, rest days)
- movement cues for LE mechanics
What are some PT rx for IT band syndrome?
- POLICED
- Pt. ed
- address impairments
- MET
What is the primary purpose of MET for IT band syndrome?
- tendon proliferation and stabilization (hip and lumbar)
