The orthopedic system includes electronic circuitry, a sensor, and a remote system to monitor and measure. The sensor is configured to measure color or turbidity. The electronic circuitry is coupled to and interfaces with the sensor. The electronic circuit includes a transmitter to transmit measurement data from the sensor to the remote system. The orthopedic system is configured to monitor color or turbidity of a fluid in proximity to the muscular-skeletal system. The orthopedic system can transmit a signal when a predetermined color is detected or when the turbidity of the fluid exceeds a predetermined value. Alternatively, the remote system includes a processor and software configured to analyze the measurement data from the sensor and transmit a signal when a predetermined color is detected or when the turbidity of the fluid exceeds a predetermined value. ## Claims ### Claim 1 An orthopedic system comprising: a sensor configured to measure color or turbidity; electronic circuitry coupled to the sensor where the electronic circuitry includes a transmitter and where the orthopedic system is configured to monitor color or turbidity in proximity to the muscular-skeletal system; and a remote system configured to receive measurement data from the sensor. ### Claim 2 (depends on 1) The orthopedic system of claim 1 where the system is configured to monitor a fluid and where the electronic circuitry is configured to transmit a signal when the color or turbidity indicates a presence of an infection. ### Claim 3 (depends on 1) The orthopedic system of claim 1 where the remote system is configured to receive color or turbidity measurement data and where the remote system includes a processor configured to process the measurement data. ### Claim 4 (depends on 3) The orthopedic system of claim 3 where the remote system is configured to initiate a response when a predetermined color is detected or when the turbidity is a predetermined value. ### Claim 5 (depends on 1) The orthopedic system of claim 1 where the orthopedic system monitors a rate of change of color or turbidity. ### Claim 6 (depends on 1) The orthopedic system of claim 1 where the orthopedic system is configured to illuminate a region of interest. ### Claim 7 (depends on 6) The orthopedic system of claim 6 further including at least one light emitting diode configured to illuminate the region of interest and at least one photo-detector configured to monitor color or turbidity. ### Claim 8 (depends on 1) The orthopedic system of claim 1 further including a housing where the electronic circuitry is in the housing and where the housing is configured to couple to the muscular-skeletal system. ### Claim 9 (depends on 8) The orthopedic system of claim 8 where the housing is a prosthetic component. ### Claim 10 (depends on 1) The orthopedic system of claim 1 where a housing of the sensor is configured to couple to the muscular-skeletal system. ### Claim 11 An orthopedic system comprising: a sensor configured to measure color and turbidity; electronic circuitry coupled to the sensor where the electronic circuitry includes a transmitter and where the orthopedic system is configured to measure color and turbidity in proximity to the muscular-skeletal system; and a remote system configured to receive measurement data from the sensor. ### Claim 12 (depends on 11) The orthopedic system of claim 11 where the electronic circuitry is configured to transmit a signal indicating when a predetermined color is detected or when turbidity is a predetermined value. ### Claim 13 (depends on 11) The orthopedic system of claim 11 where the remote system is configured to receive color or turbidity measurement data, where the remote system includes a processor configured to process the color or turbidity measurement data, and where the remote system is configured to transmit a signal when a predetermined color is detected or when turbidity is a predetermined value. ### Claim 14 (depends on 11) The orthopedic system of claim 11 where the orthopedic system is configured to measure a rate of change of color or turbidity. ### Claim 15 (depends on 11) The orthopedic system of claim 11 where the orthopedic system is configured to illuminate a region of interest. ### Claim 16 (depends on 15) The orthopedic system of claim 15 further including at least one light emitting diode configured to illuminate the region of interest and at least one photo-detector configured to monitor color or turbidity of the region of interest. ### Claim 17 (depends on 11) The orthopedic system of claim 11 further including a housing where the electronic circuitry is in the housing and where the housing is configured to couple to the muscular-skeletal system. ### Claim 18 (depends on 17) The orthopedic system of claim 17 where the housing is a prosthetic component. ### Claim 19 (depends on 11) The orthopedic system of claim 11 where the sensor is in a housing and where the sensor is configured to couple to the muscular-skeletal system. ### Claim 20 An orthopedic system comprising: an optical sensor configured to monitor color and turbidity; electronic circuitry coupled to the optical sensor where the electronic circuitry includes a transmitter and where the orthopedic system is configured to measure color and turbidity in proximity to the muscular-skeletal system; a light emitting diode configured to illuminate a region of interest; and a remote system configured to receive measurement data from the optical sensor.
