The Veteran's claims for increased ratings and separate rating were partially granted. The Board granted a 20 percent rating for right knee dislocated cartilage prior to July 14, 2016; denied an initial rating in excess of 20 percent from July 14, 2016, for the same condition; denied a rating in excess of 10 percent for right knee limitation of flexion prior to October 5, 2021; granted a separate 10 percent rating for right knee slight instability from August 18, 2017; and denied entitlement to TDIU.

The Board denied service connection for pes planus (flat feet) and remanded several other issues, including service connection for various disorders and increased ratings for the right knee. The Board granted a 20 percent rating for right knee instability.

The Board denied service connection for bilateral hearing loss and denied increased ratings for sleep apnea, left ankle scar, painful left ankle scar, acquired psychiatric disability (major depressive disorder and generalized anxiety disorder), left foot metatarsalgia, and right knee limitation of flexion. The Board granted a 20 percent rating for left foot neuropathy and 20 percent rating for right knee limitation of extension.

The Board granted service connection for left and right knee locking, but remanded evaluations greater than 10 percent for bilateral knee limitation of flexion, limitation of extension, and scars.

The Board denied the Veteran's claim for special monthly compensation based on a need for aid and attendance, as her service-connected disabilities did not necessitate regular assistance from another person. The claim for housebound criteria was dismissed as it had already been granted in a previous decision.
