Abstract
The combination of a motor driven oscillating orthopedic reshaping and resurfacing tool and multiple surface-matching sheet metal prostheses minimally resurface bones of the knee and other joints. Said resurfacing tool incorporates multiple interchangeable cutting heads, each configured to conform to the anatomical surface of a different bone end of the knee joint or other joint, and incorporates a replaceable elastomeric cover having an annular containment cup with an incoming sterile-liquid tube and an out-going waste-liquid tube to flush debris from the surgical site. Each said prostheses, stamped from orthopedic metal sheet and having at least one mounting attachment, is configured to conform to the anatomical surface of a different bone end of the knee joint, or other joint, after said tool has resurfaced that bone end. When implanted onto said bone end, a prefect fit is achieved.
