Abstract
An adjustable housing suitable to be used with another housing and with a synthetic ligament so as to provide (for example) an anterior cruciate ligament prosthesis system for a knee joint is provided. The adjustable housing features an interior having a step shoulder located therein. A set screw in the housing fixes the synthetic ligament at a desired level of tension. The system has many significant advantages including (but not limited to) being able to withstand very high loads and being able to be retensioned repeatedly and easily without replacing the artificial ligament.
