sci.joint-contact-force-knee Calculator
Calculates knee joint contact force during activities from external moments and muscle force estimates using a static musculoskeletal model. Peak knee contact force during walking: ~2.5 BW; running: 5–8 BW — forces above 7–8 BW are associated with increased cartilage degradation and OA progression.
Inputs
Bw N
Body or object weight. For health calculators, usually in kg or lbs.
Activity
Reference formula or conversion factor shown for context.
Results
knee joint contact force (N)
Sample size or count used in the calculation.
knee contact force (× BW)
Sample size or count used in the calculation.
estimated hip contact force (N)
The value at the specified point or condition.
activity
Rate of radioactive decay events per second (becquerels or curies). Decreases exponentially with time.
