What is claimed is: 1. A method of treating a patient with osteoarthritis, said method comprising: implanting a system control unit at least partially within said patient; configuring one or more stimulation parameters to treat osteoarthritis; programming said system control unit with said one or more stimulation parameters; generating a stimulus configured to treat said osteoarthritis with said system control unit in accordance with said one or more stimulation parameters; and applying said stimulus to a stimulation site within said patient; wherein said stimulation site comprises at least one or more of an artery supplying a joint affected by said osteoarthritis, a spinal cord, a spinal segment supplying somatic sensation at said affected joint, a spinal segment supplying sympathetic control of said affected joint, a sympathetic ganglia, a nucleus gracilis, a nucleus cuneatis, a cranial nerve, a deep brain location, a hypothalamus, a thalamus, and a motor cortex; wherein said system control unit is coupled to one or more electrodes disposed on an outer surface of said system control unit; and wherein said stimulus comprises a stimulation current delivered to said stimulation site via said electrodes. 2. The method of claim 1, further comprising coupling said system control unit to said stimulation site. 3. The method of claim 1, wherein said stimulus further comprises one or more drugs delivered to said stimulation site. 4. The method of claim 1, further comprising sensing at least one indicator related to said osteoarthritis and using said at least one sensed indicator to adjust one or more of said stimulation parameters. 5. The method of claim 4, wherein said at least one indicator comprises at least one or more of a synovial fluid level within said affected joint, the viscosity of synovial fluid within said affected joint, a distance across said affected joint, a pressure distribution across said affected joint, a vibration resulting from movement of said affected joint, a range of motion of said affected joint, an activity level of said affected joint, a smoothness of trajectory of said joint, a force exerted by one or more muscles surrounding said affected joint, electrical brain activity, a neurotransmitter level, a hormone level, a blood flow rate in said affected joint, and a medication level. 6. The method of claim 1, wherein said system control unit comprises a microstimulator. 7. A method of treating a patient with osteoarthritis, said method comprising: implanting a system control unit within said patient; configuring one or more stimulation parameters to treat osteoarthritis; programming said system control unit with said one or more stimulation parameters; generating a stimulation current configured to treat said osteoarthritis with said system control unit in accordance with said one or more stimulation parameters; and applying said stimulation current to a stimulation site within said patient; wherein said stimulation site comprises an artery supplying a joint affected by said osteoarthritis. 8. The method of claim 7, further comprising coupling said system control unit to said stimulation site. 9. The method of claim 7, further comprising sensing at least one indicator related to said osteoarthritis and using said at least one sensed indicator to adjust one or more of said stimulation parameters. 10. The method of claim 9, wherein said at least one indicator comprises at least one or more of a synovial fluid level within said affected joint, the viscosity of synovial fluid within said affected joint, a distance across said affected joint, a pressure distribution across said affected joint, a vibration resulting from movement of said affected joint, a range of motion of said affected joint, an activity level of said affected joint, a smoothness of trajectory of said joint, a force exerted by one or more muscles surrounding said affected joint, electrical brain activity, a neurotransmitter level, a hormone level, a blood flow rate in said affected joint, and a medication level. 11. The method of claim 7, further comprising delivering one or more drugs to said stimulation site. 12. The method of claim 1, wherein the stimulation site comprises the spinal cord. 13. The method of claim 1, wherein the stimulation site comprises the spinal segment supplying somatic sensation at said affected joint. 14. The method of claim 1, wherein the stimulation site comprises the spinal segment supplying sympathetic control of said affected joint. 15. The method of claim 1, wherein the stimulation site comprises the sympathetic ganglia. 16. The method of claim 1, wherein the stimulation site comprises the nucleus gracilis. 17. The method of claim 1, wherein the stimulation site comprises the nucleus cuneatis. 18. The method of claim 1, wherein the stimulation site comprises the cranial nerve. 19. The method of claim 1, wherein the stimulation site comprises the hypothalamus. 20. The method of claim 1, wherein the stimulation site comprises the thalamus.
