Patellar pad

Abstract

A medical aid for supporting the function of the knee joint, in particular a knee joint orthosis with a pad engaging around the patella of the knee joint. An improved patellar pad has the additional function of supporting movement and has additional preventive/therapeutic functions.

Claims

1. A pad for a knee joint orthosis, said pad having an annular base configured for engaging around a patella of a subject to which said pad is applied, wherein a pair of projections configured to face a knee joint of said subject are formed distally on the base and which, in a fitted state of the pad, are configured to be located in an area of infrapatellar fat bodies of said subject and are adapted to exert pressure on said fat bodies, and wherein the base additionally has lateral wing-shaped projections which, in the fitted state of the pad, are configured to come into engagement with the infrapatellar joint spaces of said subject.

2. The pad according to claim 1, wherein the projections adapted to act on the fat bodies are adjustable in terms of their mechanical properties or are exchangeable.

3. A method for applying the pad according to claim 1, wherein the method comprises: applying the pad to a knee-joint orthosis of said subject, wherein the orthosis is configured for improving and/or securing positioning of the knee-joint orthosis on the subject's knee joint.

4. A method for applying the pad according to claim 1, comprising: applying the pad to a knee-joint orthosis of said subject, wherein the orthosis is configured for preventive or therapeutic support of a congruent closure between infrapatellar joint elements of said subject.

5. A method for applying a pad according to claim 1, comprising: applying the pad to a knee-joint orthosis of said subject, wherein the orthosis is configured for preventive or therapeutic support of biomechanical function of an infrapatellar fat body of the knee joint of said subject.

6. A method for applying a pad according to claim 1, comprising: applying the pad to a knee-joint orthosis of said subject, wherein the orthosis is configured for preventive or therapeutic stabilization of the patella of the knee joint of said subject in an extension position.

7. A method for applying a pad according to claim 1, comprising: applying the pad to a knee-joint orthosis of said subject, wherein the orthosis is configured for prevention or therapy of anterior knee pain syndrome in said subject.

8. A method for applying a pad according to claim 1, comprising: applying the pad to a knee-joint orthosis of said subject, wherein the orthosis is configured for prevention or therapy of edema formation in the infrapatellar fat bodies of the knee joint of said subject.

9. A knee joint orthosis containing the pad according to claim 1.

10. A knee joint orthosis according to claim 9, which is an elastic knitted orthosis.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is a plain view of a pad according to the invention;

(2) FIG. 2 is a cross-sectional view on line a in FIG. 1; and

(3) FIG. 3 shows an alternative pad design.

DESCRIPTION OF EMBODIMENTS

(4) FIG. 1 shows a design of the pad (100) according to the invention with an annular base (10), which encloses the patella located in the recess (15). According to the invention, the base (10) has a pair of knob-like projections (20) facing toward the joint. The pad additionally has distal, lateral wing-shaped projections (30).

(5) FIG. 2 shows a cross section on the sectional line a (FIG. 1). The knob-like projections (20) protrude from the base (10) in the direction of the joint by a predeterminable height (22).

(6) FIG. 3 shows an alternative design of the pad (100) which engages distally, in a semicircular or horseshoe shape, around the patella located in the recess (15).
