Definitions
- This invention relates to knee surgery, more particularly to replacement of the anterior cruciate ligament, hereafter referred to as ACL.
- a synthetic scaffold-type ACL replacement such as that known by the trade mark ABC of Surgicraft Limited comprising carbon and polyester fibres in a braided zigzag structure has proved successful.
- Mode of failure analysis using electron- microscopy has shown that most failures (between 9% and 12% over the past 6 years) occur at the internal exit of the tibial drill hole.
- the object of the present invention is to provide a drill jig probe which facilitates the correct positioning of the tibial drill hole without direct visualisation (arthrotomy) or indirect visualisation (arthroscopy) .
- an ACL drill jig probe comprises a location portion for securing in an ACL drill jig, a shank extending from the location portion for passing one side of the patella tendon, and a horn extending from a junction with the shank at an obtuse angle for location against the posterior part of the intercondylar notch as the anatomical reference point for an ACL drill jig with which the probe is to be used.
- the shank and the horn are conveniently formed integrally by a length of round rod, e.g. of stainless steel of 4.0mm diameter, but may be of semicircular or other cross- section, with a bend (which may be slightly curved) at the junction between the shank and the horn, and the free end of the horn is preferably rounded-off.
- the other end of the shank i.e.
- the location portion which preferably consists of a length of square-section bar, e.g., of stainless steel of 8.0 mm lateral dimensions, with the corners and ends bevelled or rounded-off, and with at least one semicircular notch in one side for secure location in an ACL drill jig with which the probe is to be used.
- the shank may be straight and coaxial with the location portion, or the shank may have at least one lateral bend (which may be slightly curved) to facilitate passing of the shank round the lateral aspect of the medial femoral condyle and the patella tendon, but the shank preferably has two lateral bends (each of which may be slightly curved) in opposite directions, both to facilitate passing of the shank round the lateral aspect of the medial femoral condyle and the patella tendon and to allow ready use of the probe with an existing coplanar ACL drill jig, so that the tibial drill hole will have an axis oblique in three dimensions to the axis of the horn of the probe and with its exit end axially aligned below a point on the horn above its junction with the shank, which ensures correct positioning of the tibia drill hole with its axis oblique to the sagital, coronal and transverse planes.
- the invention preferably also provides a set of instruments comprising at least two interchangeable probes, one for a left knee - and one for a right knee, and a coplanar ACL drill jig.
- the set preferably comprises a plurality of interchangeable probes for a range of left knees and a range of right knees.
- Figure 1 is a side elevation of one such ACL drill jig probe orthogonal to its location portion
- Figure 2 is a plan of the probe of Figure 1 orthogonal to the side elevation;
- Figure 3 is a fragmentary side elevation in the direction of the arrow X in Figure 2;
- Figure 4 is a perspective view of a set of three ACL drill jig probes in accordance with the invention
- Figure 5 is a perspective view of a coplanar ACL drill jig with the probe (b) of Figure 4 applied to a model right knee, along with a drill;
- Figure 6 is a fragmentary elevation showing how the location portion of the probe is located in the jig
- Figure 7 consists of two small scale diagrams showing the disposition of the probes (a) and (b) of Figure 4 in relation to parts of left and right knees respectively;
- Figure 8 is an enlarged fragmentary section in a plane coincident with the axis of the tibial drill hole, showing part of the drill which has formed it and part of the probe which has been used for its accurate location.
- the ACL drill jig probe shown in Figures 1 to 3 of the drawings comprises a location portion 10 for securing in an ACL drill jig 20 (as will be described presently with reference to Figures 5 and 6), a shank 11 extending from the location portion for passing one side of the patella tendon 21 (see also Figure 7), and a horn 12 extending from a junction 13 with the shank at an obtuse angle for location against the posterior part 22 (see Figure 8) of the intercondylar notch 23 as the anatomical reference point for the ACL drill jig with which the probe is to be used.
- the shank 11 and horn 12 are formed integrally by a length of stainless steel round rod of 4.0 mm diameter with a sharp bend at the junction 13, and the free end 14 of the horn is rounded-off.
- the other end of the shank 11 is secured as by pinning or cementing in a hole 24 (see Figure 6) in one end of the location portion 10 which consists of a length of stainless steel square-section bar of 8.0 mm lateral dimensions, with the corners and ends bevelled or rounded-off, and with a semicircular notch 15 in one side for secure location in the ACL drill jig with which the probe is to be used.
- the shank has two bends 16, 17 in opposite directions, so that the tibial drill hole 26 (see Figure 8) will have an axis oblique in three dimensions to the axis of the horn 12 of the probe and with its exit end (indicated at 18 in Figure 2) axially aligned below a point on the horn 12 above its junction 13 with the shank 11 which ensures the correct positioning of the tibial drill hole without direct visualisation (arthrotomy) or indirect vis ⁇ alisation (arthroscopy) .
- the location portion 10 of a probe having a square section is a close fit in a groove 27 across the body 28 of the coplanar ACL drill jig 20, and is provided with a second semicircular notch 15X of larger diameter than the notch 15 so that engagement of the notches 15, 15X with pegs 29, 29X of corresponding respective diameters projecting into the groove 27 ensure that the probe will be located with the shank 11 and horn 12 projecting in the right direction.
- the prove is made secure in the jig when a sliding clip 30 is pushed into place over the groove 27.
- the probes (a) and (b) in Figures 4 and 7 are recommended for general use, while the probe (c) in Figure 4 has a straight shank 11 and is suitable for use in arthroscopic reconstruction with insertion via a central portal.
