Purpose:This article is focused on the effect of femur compressive strength mechanical properties and stretch strength mechanical properties about uygur sand therapy.Method:Compression experiment:30 New Zealand rabbits were divided randomly into three different groups

14 sand therapy group

10 drug therapy group and 6 normal group

Papain was injected into the joint space of right knee of rabbits for 14 sand therapy group and 10 drug therapy group to establish model genu osteoarthritis

normal group did not treat in any way.Three-point bending test:Papain was injected into the joint space of right knee of 20 New Zealand rabbits to establish model genu osteoarthritis.The Paptain injected rabbits were divided randomly into two different groups:sand therapy group and control group.The control group rabbits weren't interfered in any way.The sand therapy group rabbits were given sand therapy for 30 minutes each day for 15 days.The drug therapy group rabbits were given drug therapy for 15 days.Results:By compression experiment

the sand therapy group showed high compressive strength than drug therapy group;By threepoint bending test

the sand therapy group showed high tensile strength than control group.Conclusion:Sand therapy can improve femur compressive strength mechanical properties and tensile strength mechanical properties.
