Systems and methods for knee joint therapy

A knee joint rehabilitation system comprising:

• a knee joint flexion device, comprising:
• a tubular strut having a first support foot and a bracket attached thereto or configured for attachment to the tubular strut, the tubular strut forming a first aperture;
• a height-adjustment bar configured to be translatably disposed in the tubular strut when coupled thereto, the height-adjustment bar forming a plurality of second apertures extending through a diameter of the height-adjustment bar;
• a support bar fixedly connected substantially perpendicularly to the height-adjustment bar, the support bar being configured for receiving at least one of a plurality of pads so as to provide a padded support bar, the padded support bar being configured to receive a knee joint posterior;
• said plurality of pads being configured to removably mount to the support bar, each pad having an outer diameter different from that of another of said plurality of pads;
• a support strut pivotably connected to the bracket when the knee joint flexion device is in an assembled form, the support strut having a second support foot attached thereto, the support strut pivotable away from parallel the tubular strut to form an angle thereto;
• a pin configured for removable positioning in one of the plurality of second apertures to fix the height-adjustment bar against translation;
• a lower leg support connected to the height-adjustment bar using a first joint so as to allow for changes in an angular position between said lower leg support and said height-adjustment bar when the position of the lower leg support is adjusted;
• and
• a first actuator including a first end and a second end, said actuator being pivotably connected to the lower leg support at said first end and pivotably connected to the height-adjustment bar at said second end.

A knee joint rehabilitation system comprising:

• a height-adjustment bar;
• a plurality of support bars, each support bar among the plurality of support bar being configured for removable coupling to the height-adjustment bar, each of the support bars being configured to receive a knee joint posterior;
• the plurality of support bars being configured for providing different effective diameters when individual support bars among the plurality of support bars are mounted to the height-adjustment bar;
• and
• a lower leg support connected to the height-adjustment bar using a first joint or configured for connection thereto using said first joint so as to allow for changes in an angular position between said lower leg support and said height-adjustment bar when the position of the lower leg support is adjusted;
• an actuator configured for extension and retraction so as to adjust the position of said lower leg support, the actuator including a first end and a second end, the actuator being pivotably connected to the lower leg support at said first end and pivotably connected to the height-adjustment bar at said second end.
