Q angle
❖ Q angle can be increased by:
❖ excessive femoral anteversion
❖ external tibial torsion
❖ genu valgum
❖ subtalar hyperpronation
Hip Musculature
❖ Hip External Rotators
❖ Gluteus Maximus and Medius
❖ Piriformis
❖ Obturator muscles
❖ Gemellus muscles
Common Knee Injuries
❖ Patellofemoral Pain
❖ Knee OA
❖ IT Band Syndrome
❖ Hip Flexor Pathology
❖ Patellar Tendonitis
❖ Meniscus Pathology
❖ Ligament Injuries
6
Patellofemoral Biomechanics
❖ PF Force transmission
❖ CKC 0-20 deg: pressure is primarily on patellar tendon
❖ In mini squat, as flexion angle increases, quad accepts more load
❖ 45 deg and beyond; more quad force than patellar tendon force
Clinical Applications
❖ Patellar tendon: squat 45-120 deg
❖ PF arthritis: CKC 0-30 deg
❖ PF Instability: 40-90 deg
Patellofemoral Pain
❖ s/s: global knee pain; sharp at times; click?
❖ Picture of PF joint
❖ Causes of patella mal-tracking
❖ What can we actually change?
❖ Pressures on patella at different angles
❖ The knee is stuck between the foot/ground and hip
7
Classification SystemKevin Wilk
❖ Compression
❖ Tension
❖ Instability
❖ Friction
Patella and Trochlear Groove Contact
❖ As flexion angle increases, the contact area moves from proximal to distal on the femur and from distal to proximal on the patella
❖ Femoral rotation creates increased PF contact pressures on the contralateral patellar facets
❖ Tibial rotation creates increased PF contact pressures on the ipsilateral patellar facets
Patellofemoral Biomechanics
❖ PF contact areas
❖ 0 degrees: patella above trochlea
❖ 10 deg: initial contact
❖ 90 deg: Increase contact from inferior pole towards superior pole
❖ 135 deg: “odd” facet contact
❖ any imbalance of contact and compression increases articular degeneration
8
Trochlear Groove
Tight Gastroc Soleus
❖ If inflexible, may not allow for full ankle DF
❖ Results in compensatory increase in subtalar pronation
❖ Encouraging lateral tracking of the patella
PFP Treatment
❖ Improve flexibility in HS, hip flexors and IT Band
❖ Increase strength in glutes, hip rotators
❖ Balance and proprioceptive training
9
Knee OA
❖ s/s: painful crepitus, deeper achy pain, edema
❖ stat on incidence of knee OA
❖ current medical treatments ie carticel, microfracture, hyalgen
❖ meds to assist
❖ when is it time to have TKA?
Knee OA Treatment
❖ need to find pain free ranges form strengthening
❖ tough patients as they are easy to flare up
❖ NSAIDs, hyalgen injections
❖ Activity modification
❖ Isometric Strengthening
❖ Assess footwear
IT Band Syndrome
❖ s/s: pain in lateral knee, thigh and/or hip
❖ Comes off the Tensor Fascia Latae
❖ attaches on Gerdy’s tubercle
❖ what is the role of the ITB?
❖ assess pelvic alignment
10
Function of the IT Band
❖ As the knee flexes 30 degrees, its function changes from an extensor to a flexor
❖ The iliotibial tract helps prevent the pivot-shift
❖ In combination of the pelvic deltoid muscles, the ITB assists with LE postural control during gait
Thomas Test❖ easiest way to assess for IT Band tightness
ITB Syndrome Treatment
❖ stretching of restricted tissues
❖ medial patellar glides and tilts
❖ cross friction to distal and central ITB
❖ Quad strengthening and McConnell taping
❖ modalities: US, ionto with dexamethasone
❖ AIS rope stretches
❖ Foam Roller
11
Hip Flexor Pathology
❖ s/s: anterior hip pain, groin pain, lower back pain
❖ beginning to think plays a huge roll in many lower quarter injuries
❖ hip flexor tightness puts increased strain on lower back and groin structures
❖ common in patients that sit a great deal at work or in car, golfers, hockey players, cyclists
❖ Origin: lateral surface of vertebral bodies T12 to L5
❖ Insertion: lesser trochanter
Thomas Test for Hip Flexor
❖ Iliopsoas vs Rectus Femoris
❖ If rectus, knee will be extended more
12
Hip Flexor Treatment
❖ Check SI alignment
❖ #1 thing you can do is release the iliopsoas!!
❖ AIS stretches
❖ Foam Roller
Iliopsoas Release
Patellar Tendonitis
❖ s/s: anterior knee pain; tenderness to palpation of patellar tendon
❖ “Runner’s Knee” or “Jumper’s Knee”
❖ more chronic it is, the harder it is to treat
❖ can be very painful
13
Patellar Tendonitis Treatment
❖ modalities: ice, US, ionto with dexamethasone
❖ cross friction massage
❖ Cho-pat strap
❖ biomechanical training (orthotics?)
❖ PRP injection ??
Meniscus Pathology
❖ s/s: catching or locking in the knee; joint line pain
❖ one of the only pathologies where I push for surgery
❖ loss of “brake pads”
❖ acute vs degenerative
❖ carry 50-60% of compressive load across the knee
❖ At 90 deg of flexion, load increases to 85%
14
Meniscus Pathology❖ Medial meniscus is most oftenly injured because of its
adherence to the MCL
❖ With the foot planted, any direct blow to the lateral aspect of the knee can injure the MCL and medial meniscus
❖ Medial compartment takes greater weight bearing loads during gait which lends to having increased degeneration over time
Debridement vs. Repair
❖ If debrided, much quicker recovery but now patient is functioning on less than 100% brake pads.
❖ MUST let debridement heal up, scar over and get LE strength as maximal as possible.
❖ If repaired, what are the guidelines in regards to weight bearing? ROM?
❖ Prefer repair long term although return to activity is delayed
Debridement vs Repair
15
Meniscus Injury Treatment
❖ Whether it is a meniscectomy or repair, be aware of the depth of squats!
❖ At 90 degrees of knee flexion, meniscus carries 85% of body weight
MCL Injuries
❖ s/s: pain over medial compartment, feeling of instability with valgus movement
❖ very rarely operated on!
❖ how many more times larger than LCL or ACL/PCL?
❖ a lot of times occurs in conjunction with other pathology
Grading Ligament Injuries
❖ Grade 1: <5-mm joint line opening with stress
❖ Grade 2: 5 to 10mm joint line opening with stress
❖ Grade 3: >10-mm joint line opening with stress
16
MCL Injury Treatment
❖ #1: Protect the healing fibers!
❖ Road Runner Brace
❖ Strengthen quad/hamstrings/glutes
❖ Balance and proprioceptive training
❖ Limit valgus movements early on
❖ get controlled ROM early on
ACL Injuries❖ s/s: general knee pain; feeling of instability or giving way
with activities such as descending steps, running or walking
❖ operative vs non-operative treatment
❖ initial goals are to control edema, quad activation and restore normal knee ROM
ACL TreatmentNon-operative
❖ eliminate edema
❖ quad activation
❖ restore normal knee ROM
❖ Proprioceptive exercises
❖ Quad dominant knees can sometimes get away without an ACL depending on level of activity
❖ Need to be careful of potential arthritic changes
17
ACL Surgery Options
ACL Reconstruction
❖ Hamstring Autograft
❖ Patellar autograft (ipsilateral/contralateral)
❖ Hamstring Allografts
❖ Patellar Tendon Allografts
❖ Achilles Tendon Allografts
❖ Single bundle vs Double Bundle
51
Double Bundle ACL Reconstruction
51

52
• Origin: Posterior medial aspect of the lateral
femoral condyle.
• Insertion: Anterior middle aspect of the tibial
plateau & anterior to the intercondylar
eminence.
• Action: Limits anterior translation and
internal rotation of the tibia in relation to the
femur.
The knee – Anterior Cruciate Ligament

53
• An athletic or non-athletic related activity in
which the knee is forced into hyperextension and/or internal rotation may
result in an ACL tear.
Structure of the ACL
Picture 11
54
• The ACL is referred to as one ligament
consisting of two bundles.
• Anteromedial Bundle – AM
• Posterolateral Bundle – PL
Structure of the ACL
Picture 12
19
55
• Antromedial Bundle – AM
• Origin: Originates more anteriorly on the
tibia.
• Insertion: Inserts more medially on the
femur.
• Posterolateral Bundle – PL
• Origin: Posterior of the AM bundle on the tibia.
• Insertion: Inserts lateral of AM bundle on
the femor.
Structure of the ACL
Picture 13
56
• Function of Bundles
• Extension
• Anteromedial Bundle – AM: Works in conjunction with PL bundle to resist anterior
displacement of tibia on the femur.
• Posterolateral Bundle – PL: Works in conjunction with AM bundle to resist
anterior displacement of tibia on the femur.
Structure of the ACL
Picture 14
57
• Function of Bundles
• Flexion – Bundles cross in knee
flexion.
• Anteromedial Bundle – AM: Resists anterior
displacement of tibia on femur.
• Posterolateral Bundle – PL: Becomes loose in knee flexion to allow for rotation of the
knee.

58
• Double-Bundle Technique
1. Definition of the ACL as a ligament with two
functional bundles.
2. Anteromedial (AM) bundle accounts for
forward movement of the tibia under the
femur, while the postrolateral bundle controls rotational stability of the knee.
3. Identifies two origin and insertion sites of
the ACL with the DB surgery duplicating both sites.
Single-Bundle Technique
1.Definition of the ACL as a single ligament.
•ACL accounts to forward movement of the tibia under the femur, but does not fully
address complete rotational stability of the
knee.
•Identifies single origin and insertion site and
performs the surgery accordingly.
Surgical Procedures
Double-bundle vs single-bundle technique
59
• Double-Bundle Technique
4. Reproduces an individual’s native anatomy.5. Patients report less pain and more stability
following DB surgery.
6. Decreased occurrence of arthritis.
7. More knee stability reported.
8. Normal range of motion.
Single-Bundle Technique
4.Does not reproduce an individual’s native anatomy.
•More patients report pain and less stability
following SB surgery.
•Increased occurrence of arthritis.
•Less knee stability reported.
•Range of motion can be compromised.
Surgical Procedures
Double-bundle vs single-bundle technique
60
• The most popular ACL surgery in the United
Sates is the Single-Bundle Technique.
• The Single-Bundle Technique does not replicate the individual’s normal or “native” anatomy.

*****DANGER ZONE***** the highest incidence of re-tears occurs during
this time frame. At this point, the graft is at its weakest. Concurrently the
athlete feels secure with their knee and can sometimes do ill advised activities
that can compromise the integrity of the graft.

(<10% difference)
24
FYINO running before 12 weeks.
This is a very frustrating time for both clinician
and athlete due to lack of progression.
However, this is the most important time to
continue strengthening, balance, proprioception
and core training.
Challenge core, cardio and upper body strength.
Weeks 12-16
Continue strengthening exercises increasing weight, reps, sets
Consider consult with Sport Psych if needed

If girth measurement differences were > 10%,
alter training to incorporate lower reps/heavier
weight to encourage hypertrophy.
25
Weeks 16+
Re-test FMS
Sport specific training
oComplete training in the setting of the
sport ( basketball court, soccer field)
OKC vs CKC for ACL
❖ during open chain active knee extension, the maximum stress on the ACL occurs at 20 degrees
❖ recent studies have stated that it is ok to do OKC strengthening for post op ACLs early on but......
❖ do we want single muscle firing or prefer closed chain for more functional strengthening??
Plasma Rich Platelet Injections
❖ More long term studies needed but PRP injections are promising in early studies
❖ Uses red blood cells from platelets that release growth factors
❖ Could help the body heal itself at a faster rate
26
Restoring Immediate ROM and Strength
❖ Focus on restoring full knee extension asap
❖ Prevents scar tissue from forming and causing an extension block
❖ Edema can cause up to 20% deficit in quad activation
Restoring Immediate ROM and Strength

Dynamic Warm Up
❖ Have to prepare the muscles, joints, ligaments, GTO’s for athletic movements.
❖ Static stretches just don’t get it and actually decrease power/speed output and effect athletic performance
❖ Maintain good posture and tightened core throughout

Proprioceptive Training
❖ Critical for return to athletic movements
❖ Need to get all the muscles firing at the right time by stimulating the muscle spindles
❖ Stable vs Unstable Surface
❖ Eyes Open/Closed
❖ External Forces
❖ Vibration training
32
LE Proprioceptive Exercises
❖ Single leg stance
❖ Star reaches
❖ Airex pads
❖ BOSU balls
❖ I joy
33
Hip Activation Exercises
❖ Can hip weakness contribute to knee pain?
❖ From initial contact to midstance, the hip rotates internally
❖ External rotators must control this eccentrically
❖ If they are weak, will have excessive hip IR which functionally increases the Q-angle
Hip Activation Exercises
❖ Important to get the hip musculature activated prior to athletic participation
❖ Also important in assisting with control of the LE when moving in space

Maintaining Tissue Mobility
❖ Whether there is a pathological injury or if due to excessive training, for efficient athletic movements you have to maintain normal tissue mobility
❖ Massage, foam roller, stick are all effective ways to accomplish this
❖ Sx of soft tissue adhesions include: decreased ROM, muscle weakness and pain, compensatory patterns and paresthesia.
36
Massage
❖ Good for improving tissue mobility
❖ Improves edema flow
❖ Improves blood flow
Foam Roller IT Band
Foam Roller Quad/Hip Flexor
37
Foam Roller Piriformis
Stick
Total Knee Rehab for the Athlete
38
Mobile Bearing Knee
Rehab for the Total Knee Athlete
❖ As with all knees, emphasize edema control, patellar mobility, IT Band mobility, quad activation and extension ROM
❖ Once you get to the 8 week mark and all bony damage is healed up, you can turn up the intensity
❖ Need strong hip IR and ER and proprioception so the knee does not take the torsional stress
Return to Sport Training
❖ critical to train in all 3 planes to mimic return to sport
❖ reps, reps, reps
❖ footwork!
