1. A pulsed electro-magnetic field (PEMF) stimulation apparatus for treatment of osteoarthritis of a knee of a user, the apparatus comprising:
an applicator that can be wrapped around a leg of the user;
a first multi-turn rectangular coil disposed in the applicator, the first multi-turn rectangular coil comprising an upper horizontal side, a lower horizontal side, a left vertical side and a right vertical side;
a second multi-turn rectangular coil disposed in the applicator, the second multi-turn rectangular coil comprising an upper horizontal side, a lower horizontal side, a left vertical side and a right vertical side; and
a third coil disposed in the applicator,
wherein the first multi-turn rectangular coil is located in the applicator such that each of the upper horizontal side and the lower horizontal side thereof are wrapped around at least a majority of a circumference of the leg above the knee of the user when the applicator is wrapped around the leg of the user and such that the upper horizontal side is positioned to create a loop above the knee outside a treatment zone of the knee while the lower horizontal side is positioned to create a loop in the treatment zone of the knee when the applicator is wrapped around the leg of the user,
wherein the second multi-turn rectangular coil is located in the applicator such that each of the upper horizontal side and the lower horizontal side are wrapped around at least a majority of the circumference of the leg below the knee of the user and such that the lower horizontal side is positioned to create a loop below the knee outside the treatment zone of the knee while the upper horizontal side is positioned to create a loop in the treatment zone of the knee when the applicator is wrapped around the leg of the user, and
wherein the third coil overlies a patella when the applicator is wrapped around the leg of the user.
