Musculoskeletal (Knee) Flashcards
PFP Pathophysiology
Patella mal tracking and patella trochlear groove variability can result in PFJ stress, can be the hereditary irregular shape of the bones, possibly related to imbalances of forces at the knee
PFP Aetiology
- Multifactorial = structure, biomechanics, load, volume and intensity.
- Primary culprit suspected to be subcondral bone due to dense nociceptive fields.
PFP Prognosis
50% of people will report symptoms beyond 5 years of diagnosis (Lack et al., 2018)
PFP Management
exercise, movement retraining and load management (Lack et al., 2018). Hip strengthening, knee strengthening, orthotics, neoprene sleeve, taping
Patella Tendinopathy Pathophysiology
Tendon microtrauma from overloading of the tissue leading to alterations at the cellular level which weaken the mechanical properties
Patella Tendinopathy Aetiology
Chronic repetitive tendon overload is the most common theory, another theory is inferior patellar pole impingement though this has not been proven biomechanically
Patella Tendinopathy Prognosis
Can take several months or longer (Malliaras et al., 2015), after 12 months only 46% of athletes were pain-free following an eccentric strength training program (Bahr et al., 2014)
Patella Tendinopathy Management
Activity management, and eccentric loading should be the first line Rx for PT (Challoumas et al., 2021).
Management of PFP
LACK ET AL., 2018 (SR)
Exercise therapy (training the hip and thigh muscles)
* Proximally targeted exercise when added to knee targeted exercise may improve symptoms
* Exercise can improve function the short, medium and long term of PFP
* Proximally CKC targeted exercise may improve pain and function to a greater extent than knee targeted exercise
Secondary / Supplementary
* Movement/Run retraining
* Taping
* Foot Orthoses
* Neoprene sleeves
* Education, have been shown to be effective in the management and Rx of PFP
Management of PT
CHALLOUMAS ET AL., 2021 (MA)
* Eccentric loading with or without adjuncts should remain the first-line treatment for all individuals with patellar tendinopathy
* Shockwave provides limited clinical benefits

What were the Key findings of Neal et al (2022) regarding the treatment of PFP?
- Non-surgicall treatments are appropiate for people with PFP
- Knee exercise therapy, combined interventions, foot orthoses, and knee focused manual therapy all showed primary efficacy when compared to a “wait and see approach”
- Combined hip and knee with perineural injection and combined intervetntions each showed increased efficacy when compared to knee-focussed exercise therapy alone
- Only foot orthoses and hip-and- knee-targeted exercise therapy combined with hyaluronic acid injection have been adequately tested beyond a short-term follow-up.
What are the six phases of ACL rehabilitation (with reference)?
- Preop Phase: Injury recovery & readiness for surgery
- Phase 1: Recovery from surgery
- Phase 2: Strength & neuromuscular control
- Phase 3: Running, agility, and landings
- Phase 4: Return to sport
- Phase 5: Prevention of re-injury
(Melbourn ACL Rehabilitation Protocol)
What are the five principals of ACL rehabilitation.
- **Get the knee straight early **(within the first 2-3 weeks both post injury and post surgery), and keep it straight. Flexion can progress gradually.
- Use knee pain and knee swelling as a guide. If either or both are increasing, the knee isn’t tolerating what you’re doing to it.
- Technique is everything. Compensation patterns develop after an ACL tear, so focusing on correct muscle and movement/biomechanical patterns is paramount.
- Build high impact forces gradually. The articular structures in the knee joint will take time to adapt to a resumption of running, jumping and landing.
- Complete your ACL rehabilitation. Once people are back running with no knee pain it’s easy to think that it’s all done. But the last 1/3 of the protocol is the most important – to help reduce the chance of re-injury, increase the chance of a successful return to sport, and possibly to reduce the likelihood of osteoarthritis down the track.
