Abstract
Abstract A method of surgical repair using a needle having two sharpened ends, under arthroscopic control by passing a needle into the joint until the eye of the needle just emerges from the skin on the distal side of the joint, then pulling the suture through the joint to the outside while the needle remains partially within the joint capsule and passing the needle back to the opposite side of the joint so as to reverse the maneuver, so that the needle remains partially within the joint capsule.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
226 words
A method for surgical repair, under arthroscopic control, of a lesion in a tissue of a limb joint of a mammal comprising the steps of: (a) inserting a straight needle, carrying a suture previously knotted at one end, via the end distal from an eccentrically placed eye aperture into the joint at the anterior medial aspect of the joint, which needle has two tapered, sharpened ends and is 0.5 to 30 cm long; (b) advancing the tip of the needle under arthroscopic control using either direct vision or television monitor control, until it reaches the medial side of the tear; (c) pushing the needle through the tissue and advancing it so that the trailing tip of the needle remains inside the joint capsule and the eye aperture of the needle is just outside the skin of the joint on the lateral side; (d) pulling the free end of the suture through to the exterior of the joint; (e) pushing the needle back through the tissue in the reverse direction until the eye aperture of the needle is just outside the skin and the tip of the longer arm of the needle is just adjacent to the tissue; (f) pulling the suture through to the exterior of the joint as in step (d); and (g) repeating the procedure as many times as required to repair the lesion.
Claim 2
Independent Claim
226 words
A method for surgical repair, under arthroscopic control, of a lesion in a tissue of a limb joint of a mammal comprising the steps of: (a) inserting a straight needle, carrying a suture previously knotted at one end, via the end distal from an eccentrically placed eye aperture into the joint at the anterior medial aspect of the joint, which needle has two tapered, sharpened ends and is 0.5 to 30 cm long; (b) advancing the tip of the needle under arthroscopic control using either direct vision or television monitor control, until it reaches the medial side of the tear; (c) pushing the needle through the tissue and advancing it so that the trailing tip of the needle remains inside the joint capsule and the eye aperture of the needle is just outside the skin of the joint on the lateral side; (d) pulling the free end of the suture through to the exterior of the joint; (e) pushing the needle back through the tissue in the reverse direction until the eye aperture of the needle is just outside the skin and the tip of the longer arm of the needle is just adjacent to the tissue; (f) pulling the suture through to the exterior of the joint as in step (d); and (g) repeating the procedure as many times as required to repair the lesion.
Claim 3
Dependent Claim
13 words
A method according to claim 1 wherein the lesion is in a ligament.
Claim 4
Dependent Claim
17 words
A method according to claim 1 wherein the lesion is in a rotator cuff of a shoulder.
Claim 5
Dependent Claim
13 words

Claim 6
Dependent Claim
13 words

A method according to claim 4 wherein the tendon is an Achilles tendon.
Claim 8
Independent Claim
225 words
A method for repair of a peripheral tear in the lateral meniscus of the tibiofemoral joint of a mammal; comprising the steps of: (a) inserting a straight needle, carrying a suture previously knotted at one end, via the end distal from an eccentrically placed eye aperture into the knee joint at the anterior medial aspect of the joint, which needle has two tapered, sharpened ends and is 0.5 to 30 cm long; (b) advancing the tip of the needle under arthroscopic control using either direct vision or television monitor control, until it reaches the medial side of the tear; (c) pushing the needle through the meniscus and advancing it so that the trailing tip of the needle remains inside the joint capsule and the eye aperture of the needle is just outside the skin of the knee on the lateral side; (d) pulling the free end of the suture through to the exterior of the knee; (e) pushing the needle bach through the meniscus in the reverse direction until the eye aperture of the needle is just outside the skin and the tip of the longer arm of the needle is just adjacent to the meniscus; (f) pulling the suture through to the exterior of the knee as in step d; and (g) repeating the procedure as many times as required to repair the tear.
Claim 9
Independent Claim
225 words
A method for repair of a peripheral tear in the lateral meniscus of the tibiofemoral joint of a mammal; comprising the steps of: (a) inserting a straight needle, carrying a suture previously knotted at one end, via the end distal from an eccentrically placed eye aperture into the knee joint at the anterior medial aspect of the joint, which needle has two tapered, sharpened ends and is 0.5 to 30 cm long; (b) advancing the tip of the needle under arthroscopic control using either direct vision or television monitor control, until it reaches the medial side of the tear; (c) pushing the needle through the meniscus and advancing it so that the trailing tip of the needle remains inside the joint capsule and the eye aperture of the needle is just outside the skin of the knee on the lateral side; (d) pulling the free end of the suture through to the exterior of the knee; (e) pushing the needle bach through the meniscus in the reverse direction until the eye aperture of the needle is just outside the skin and the tip of the longer arm of the needle is just adjacent to the meniscus; (f) pulling the suture through to the exterior of the knee as in step d; and (g) repeating the procedure as many times as required to repair the tear.
Claim 10
Dependent Claim

Claim 11
Dependent Claim
18 words

Claim 12
Dependent Claim
17 words
A method according to claim 7 wherein the needle is passed into the joint through a cannula.
Claim 13
Dependent Claim
27 words
A method according to claim 7 wherein the needle is passed into the joint via an arthroscopic entry portal and in which a cannula is optionally used.
Claim 14

A method according to claim 7 wherein the end of the needle remains within the meniscal tissue.
Claim 15
Dependent Claim
21 words
