Abstract
Abstract A tendon stripper and leader set for stripping a tendon to a select diameter and engaging the stripped end with a tendon leader sized to the stripped tendon for positioning the tendon during bone attachment or other procedures. The tendon stripper is formed as an elongated tool with a handle, a long slender neck and a tip having a coiled eyelet with a stripping edge and a side entry slot, the tendon leader comprising an elongated semirigid leader with a woven expandable end sized to enlarge over the end of a stripped tendon on installation and contract around the tendon during tension for relocating the tendon.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
A method of repairing a torn anterior crucite ligament comprising the steps of: a. arthroscopically debriding the torn anterior crucite ligament and fat pad, making an incision over the pes anserinus; b. splitting the satorius; c. stripping the semitendexiosis and gracilis tendons from connected muscle; d. detaching tendons at their upper ends; e. drilling a passage to the intercondylar notch through the medial tibial plateau from a point proximal the pes insertions and the anterior to the medial collateral ligament; f. making an incision over the lateral condylar flare; g. splitting the iliotibial band and retracting the vastus lateralis; h. drilling a passage down through the lateral femoral condyle to the intercondylar notch; i. inserting the semitendinosis and gracilis tendons up through the drilled passages using a connected tendon leader; j. securing the tendons to the lateral femoral condyle.
Claim 2
Independent Claim
139 words
A method of repairing a torn anterior crucite ligament comprising the steps of: a. arthroscopically debriding the torn anterior crucite ligament and fat pad, making an incision over the pes anserinus; b. splitting the satorius; c. stripping the semitendexiosis and gracilis tendons from connected muscle; d. detaching tendons at their upper ends; e. drilling a passage to the intercondylar notch through the medial tibial plateau from a point proximal the pes insertions and the anterior to the medial collateral ligament; f. making an incision over the lateral condylar flare; g. splitting the iliotibial band and retracting the vastus lateralis; h. drilling a passage down through the lateral femoral condyle to the intercondylar notch; i. inserting the semitendinosis and gracilis tendons up through the drilled passages using a connected tendon leader; j. securing the tendons to the lateral femoral condyle.
Claim 3
Dependent Claim
63 words
The method of claim 1 wherein the step of stripping the semitendinosis and gracilis tendons is performed with a tendon stripper having an elongated slender shank with a tip with a helically configured eyelet having an entry slot for engaging the tendon, and on rotation of the tool, encircling the eyelet enabling a reciprocal motion to strip the tendons from the connecting muscle.
Claim 4
Dependent Claim
110 words
The method of claim 1 wherein the step of inserting the semitendinosis and gracilis tendons up through the drilled passages is performed with a tendon leader having an elongated stem with a longitudinal axis, the stem being at least semirigid in construction and having a lead end and a trailing end, wherein the trailing end has connected thereto a tube of fibrous web material fashioned with a cross-weave diagonally oriented to the longitudinal axis of the elongated stem, said tube being constructed for insertion and engagement of the ends of the severed semitendinosis and gracilis tendons prior to passing the lead end of the leader up through the drilled passages.
