Abstract

Abstract Dynamic patellar brace (10) useful for both diagnosis and treatment of patellar subluxation. The brace (10) includes a patella bracing pad (15) adapted to be positioned laterally with respect to the patella having means (17,18) to apply medial pressure to the patella to prevent subluxation during flextion of the knee for all normal ranges of knee flextion and motion, and means (19) adapted to maintain the pad (15) positioned laterally of-the patella throughout said flexions when the pad (15) is in use. Preferably the pad (15) is attached to a sleeve (20) which is drawn up the leg (13) over the knee and which has an aperture (21) in its side wall to receive the patella. The patellar brace (10) may be used to facilitate positive diagnosis of patellar subluxation whose symptoms may mimic other pathological problems of the knee and, therefore, lead to an erroneous diagnosis. The brace (10) may also be used for treatment and/or to delay of avoid the need for corrective surgery.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 98 words
A dynamic patellar brace for preventing subluxation of a patella throughout the normal range of flexion and movement of the knee characterised in that it comprises a patellar bracing pad 15, means (19) adapted to maintain said pad positioned laterally of the patella throughout the normal range of flexion and movement of the knee when the brace is in use, and means (17, 18) adapted to cause said pad positioned laterally of the patella to apply medial pressure to the patella throughout the normal range of flexion and movement of the knee when the brace is in use.
Claim 2
Dependent Claim 98 words
A dynamic patellar brace for preventing subluxation of a patella throughout the normal range of flexion and movement of the knee characterised in that it comprises a patellar bracing pad 15, means (19) adapted to maintain said pad positioned laterally of the patella throughout the normal range of flexion and movement of the knee when the brace is in use, and means (17, 18) adapted to cause said pad positioned laterally of the patella to apply medial pressure to the patella throughout the normal range of flexion and movement of the knee when the brace is in use.
Claim 3
Dependent Claim 100 words
A dynamic patellarbrace according to Claim 1 characterised in that said means adapted to cause said pad to apply pressure comprises first (17) and second (18) elastic arm members, the first end of each of which is adapted to be circumferentially wrapped in a first direction about the knee when the brace is in use, and wherein said means adapted to maintain said pad laterally positioned comprises an elastic counterarm member 19, the first end of which is adapted to be circumferentially wrapped in a direction opposite to the first direction about the knee when the brace is in use.
Claim 4
Dependent Claim 41 words
A dynamic patellar brace according to Claim 1 or 2 characterised in that the medial side of said pad 15 adapted to be positioned laterally of the patella when the brace is in use is arcuately shaped, concave towards the patella.
Claim 5
Dependent Claim 75 words
A dynamic patella brace according to Claim 2 or Claim 3 characterised in that said first and second elastic arm members 17, 18 are shaped and positioned so as to be circumferentially wrapped about the knee above and below the patella, respectively. when the brace is in use, and wherein the second ends of each of said elastic arm members and the second end of said elastic counterarm member 19 are attached to said pad.
Claim 6
Dependent Claim 62 words
A dynamic patellar brace according to Claim 2 or Claims3 or 4 when appendant to Claim 2, characterised in that it comprises means operably associated with said first and second arm members and with said counterarm member and adapted to secure the' second ends of said circumferentially wrapped members to prevent the unwrapping of said members when the brace is in use.
Claim 7
Dependent Claim 44 words
A dynamic patellar brace according to any preceding claim characterised in that it further comprises an elastic sleeve 20 attached to said pad and adapted to receive a leg with the respective knee positioned substantially within said sleeve when the brace is in use.
Claim 8
Dependent Claim 34 words
A dynamic patellar brace according to Claim 3 and Claim 6 characterised in that the sleeve is provided with an aperture 21 in its side wall adjacent to the concave side of the patella.
