An intra-articular measuring device and method of using same, the device including a hollow handle defining a first passageway, and a hollow tube extending from the distal end of the hollow handle, the tube having a second passageway extending therethrough. The hollow tube carries a projection near its distal end for seating on a first selected region of a first bone, such as a tibial insertion point on a tibial plateau. The device further includes a probe slideably disposed within the first and second passageways, the hollow tube having a curvature sufficient to direct a distal end of the probe to a second selected region on a second bone, such as a femoral insertion point on a femur, to enable measurement of the distance between the first and second selected regions. Preferably, the probe includes a shaft extending proximally beyond the handle, the shaft carrying a gauge alignable with the proximal end of the handle to indicate the distance between the first and second selected regions.

A method of measuring distance between a first bone and a second, different bone in a patient, said method comprising: forming a portal in soft tissue of the patient to access the first bone and the second bone; providing an intra-articular measuring device including: a hollow handle having a distal end and a proximal end and defining a first passageway therebetween; a hollow tube having a distal end, a proximal end, and a second passageway extending therebetween, said tube proximal end being connected to said handle distal end; said hollow tube carrying a projection near said tube distal end for seating on a first selected region of the first bone; a probe slidably disposed within said first and second passageways, and having a distal end and a proximal end, said hollow tube having a curvature sufficient to direct said distal end of said probe to a second selected region on the second, different bone to enable measurement of the distance between said first selected region and said second selected region when said distal probe end is advanced distally beyond said tube distal end to said second selected region; inserting said tube distal end through the portal; placing said projection on said first selected region; advancing said probe distally beyond said tube distal end until said probe reaches said second selected region; and observing the distance between said first and second regions based on an amount by which said probe has been advanced to reach said second selected region.
