Running Biomechanics after ACL Reconstruction

📚🔬
Running Biomechanics after ACL Reconstruction
ℹ️ℹ️
INTRO:
About 250,000 ACL ruptures are reported each year in the USA.
ℹ️
Majority undergo reconstruction (ACL-R) followed by extended rehabilitation.
ℹ️
Running is a basic tenet of rehab and is critical to return to sport. 
ℹ️
The rate of return is only ~65%.
ℹ️
The incidence of a secondary ACL rupture is up to 40x greater than sustaining a primary ACL rupture.
ℹ️
Risk of OA is 4x higher in individuals after ACL rupture.
ℹ️
Return to running can begin ~ 6–8 weeks after surgery.
ℹ️
During this period, movement and muscle activation alterations are commonly observed during tasks, such as running.
ℹ️
This Systematic review looked at 
differences in movement and muscle activation for ACL-R and how it may affect running in: 
Short term (0–6 months).
Mid-term (6–12 months).
Long term (more than 12 months).
ℹ️
This will help clinicians to optimize rehabilitation to improve outcomes and long-term disability after ACL-R.
✅✅
KEY HIGHLIGHTS:
Running biomechanics alterations are reported from 3 months to at least 5 years after anterior cruciate ligament reconstruction (ACL-R). .
✅
Patellofemoral and tibiofemoral joint contact forces differed at least 2.5 years after ACL-R.
✅
Sagittal plane knee mechanics are the most altered variables during running after ACL-R. .
✅
Targeted strengthening and neuromuscular training for Quadriceps and Hamstring asymmetries should be implemented to improve running biomechanics after ACL-R.
📊📊
CONCLUSIONS:
These deficits do not resolve with time and specific clinical interventions may be needed to reduce long-term disability.

🤼‍♂️🥋 LCL Injury Series (1/3): LCL Anatomy 👇🏽 The lateral collateral ligament (LCL) originates at the outside portion of the thigh bone (femur) and inserts onto the head of the fibula. ℹ️ The LCL is one of the 4 main ligaments known to stabilize the knee.  ACL (Anterior) PCL (Posterior) MCL (Medial) LCL (Lateral) ℹ️ The LCL is quite easy to feel as it lies near the skin, on top of the IT band, separated by a Fat Pad.  ℹ️ The LCL is located on the outside portion of the knee joint and primarily protects the knee from rotational varus forces (think something crashing into the inside part of your knee and buckling it). ℹ️ The LCL is strongest and tightest from 0 to 30 degrees of knee bend.  ℹ️ As the knee bends past 30 degrees, the stability from the LCL sharply declines.  ℹ️ Using Gordon Ryan as our example, his LCL was injured when his knee was bent to about 100 degrees with his foot and lower leg twisted. ℹ️ This would have placed large f...
