<p>A ligament graft harvesting technique using a novel combination of harvesting tools comprising a patellar reamer guide (16), tibial reamer guide, and disposable reamer (10) for use with these guides, in order to harvest autogenous tissue from a patient to form a prosthetic knee ligament, with the tissue being harvested from the patella, patellar tendon and tibial component of the knee of the patient, and with the novel tool set comprising: a patellar reamer guide (16) which can be clamped to the patella of the patient so as to overlie the patella and to define a guide passage to guide the movement of a reamer through the outer surface of the patella; a disposable reamer (10) which can be driven through the guide passage so as to form a plug of patellar bone attached to an elongate portion of tendon; and a tibial reamer guide which can be clamped to the tibia of the patient (after removal of the reamer and unclamping of the patellar reamer guide), in which the tibial reamer guide defines a further guide passage to guide the movement of the reamer, or a further reamer, through the outer periphery of the tibia and substantially in line with the previously harvested patellar bone plug and elongate portion of tendon which are fed through the reamer or further reamer, after which driving of the latter through the passage in the tibial reamer guide forms a tibial bone plug integrally attached to the elongate tendon portion thereby to form a bone-patellar-ligament bone graft.</p> |
