The knee brace protects against abnormal motions of the knee, and provides direct and indirect patella stabilization. A base comprised of elastic material is configured to closely fit around portions of the knee and adjacent leg portions. The knee brace includes at least one upright support member attached to a lateral side of the base, where the upright support member is curved with an upper portion bending away from the front central axis of the brace and a lower portion that bends toward the front central axis of the brace. ## Claims ### Claim 1 A knee brace, comprising: (a) a base wearable in snug covering relationship to portions of a knee and adjacent portions of an upper leg and a lower leg of a person, the knee having a patella and the base having a first lateral side, an upper end, and a lower end; (b) a first upright support member fastened to the first lateral side, the first upright support member having a first upper portion, a first central portion, and a first lower portion, and wherein the first upright support member comprises at least one resilient stay; (c) wherein the knee brace has a front central axis when the knee brace is worn, wherein the first upper portion is at a greater lateral distance from the front central axis than the first central portion, and wherein the first central portion is at a greater lateral distance from the front central axis than the first lower portion; and (d) wherein the first lower portion extends toward the front central axis and adjacent and directly underneath at least a portion of the patella along a front surface of the lower leg, whereby the knee brace provides indirect support to the patella. ### Claim 2 (depends on 1) The knee brace of claim 1 wherein the base has a second lateral side, and further comprising (e) a second upright support member fastened to the second lateral side, the second upright support member having a second upper portion, a second central portion, and a second lower portion, and wherein the second upright support member comprises at least one resilient stay; (f) wherein the second upper portion is at a greater lateral distance from the front central axis than the second central portion, and wherein the second central portion is at a greater lateral distance from the front central axis than the second lower portion; and (g) wherein the second lower portion extends toward the front central axis and adjacent and directly underneath at least a portion of the patella along a front surface of the lower leg, whereby the knee brace provides indirect support to the patella. ### Claim 3 (depends on 1) The knee brace of claim 1 wherein the base is a tubular sleeve. ### Claim 4 (depends on 1) The knee brace of claim 1 wherein the base is an openable and reclosable sleeve. ### Claim 5 (depends on 1) The knee brace of claim 1 wherein the base includes a patella opening. ### Claim 6 (depends on 5) The knee brace of claim 5 wherein the patella opening is roughly circular. ### Claim 7 (depends on 1) The knee brace of claim 1 wherein the resilient stay includes a flattened spiral core. ### Claim 8 A knee brace, comprising: (a) a base wearable in snug covering relationship to portions of a knee and adjacent portions of an upper leg and a lower leg of a person, the knee having a patella and the base having a first lateral side, an upper end, and a lower end; (b) a first upright support member fastened to the first lateral side, the first upright support member having a first upper portion, a first central portion, and a first lower portion, and wherein the first upright support member comprises at least one resilient stay; (c) wherein the knee brace has a rear central axis when the knee brace is laid flat, wherein the first upper portion is at a lesser lateral distance from the rear central axis than the first central portion, and wherein the first central portion is at a lesser lateral distance from the rear central axis than the first lower portion; and (d) wherein the first lower portion extends toward the front central axis and adjacent and directly underneath at least a portion of the patella along a front surface of the lower leg, whereby the knee brace provides indirect support to the patella. ### Claim 9 (depends on 8) The knee brace of claim 8 wherein the base has a second lateral side, and further comprising (e) a second upright support member fastened to the second lateral side, the second upright support member having a second upper portion, a second central portion, and a second lower portion, and wherein the second upright support member comprises at least one resilient stay; and (f) wherein the second upper portion is at a lesser lateral distance from the rear central axis than the second central portion, and wherein the second central portion is at a lesser lateral distance from the rear central axis than the second lower portion; and (g) wherein the second lower portion extends toward the front central axis and adjacent and directly underneath at least a portion of the patella along a front surface of the lower leg, whereby the knee brace provides indirect support to the patella. ### Claim 10 (depends on 8) The knee brace of claim 8 wherein the base is a tubular sleeve. ### Claim 11 (depends on 8) The knee brace of claim 8 wherein the base is an openable and reclosable sleeve. ### Claim 12 (depends on 8) The knee brace of claim 8 wherein the base includes a patella opening. ### Claim 13 (depends on 8) The knee brace of claim 8 wherein the patella opening is roughly circular. ### Claim 14 A knee brace, comprising: (a) a base wearable in snug covering relationship to portions of a knee and adjacent portions of an upper leg and a lower leg of a person, the knee having a kneecap and the base having a first lateral side, an upper end, and a lower end; (b) a first upright support member fastened to the first lateral side, the first upright support member having a first upper portion, a first central portion, and a first lower portion terminating in a first lower end, and wherein the first upright support member comprises at least one resilient stay; and (c) wherein the knee brace has a front central axis when the knee brace is worn, wherein the first upper portion curves away from the front central axis and wherein the first lower portion curves toward the front central axis with the first lower end located adjacent and directly underneath at least a portion of the kneecap along a front surface of the lower leg when the knee brace is worn, whereby the first upright support member is generally shaped like the letter S and whereby the knee brace provides support to the kneecap. ### Claim 15 (depends on 14) The knee brace of claim 14 wherein the base has a second lateral side, and further comprising (d) a second upright support member fastened to the second lateral side, the second upright support member having a second upper portion, a second central portion, and a second lower portion terminating in a second lower end, and wherein the second upright support member comprises at least one resilient stay; and (e) wherein the knee brace has a front central axis when the knee brace is worn, wherein the second upper portion curves away from the front central axis and wherein the second lower portion curves toward the front central axis with the second lower end located adjacent and directly underneath at least a portion of the kneecap along a front surface of the lower leg when the knee brace is worn, whereby the second upright support member is generally shaped like the letter S and whereby the knee brace provides support to the kneecap. ### Claim 16 (depends on 14) The knee brace of claim 14 wherein the base is a tubular sleeve. ### Claim 17 (depends on 14) The knee brace of claim 14 wherein the base is an openable and reclosable sleeve. ### Claim 18 (depends on 14) The knee brace of claim 14 wherein the base includes a patella opening. ### Claim 19 (depends on 18) The knee brace of claim 18 wherein the patella opening is roughly circular. ### Claim 20 (depends on 14) The knee brace of claim 14 wherein the resilient stay includes a flattened spiral core.
