Problems solved by technology

Problems of the patella-femoral joint are a common cause of knee pain.
This conventional technique is thought to decrease force across the patella-femoral joint and thus diminish the pain arising from excess force against a worn-out patellar or trochlear cartilage.
Although available, surgical options to realign the patella may be very invasive.

Abstract

A method and system provide and use a patellar implant. The patellar implant includes a superior portion, an inferior portion opposite to the superior portion, and an anterior portion. The superior portion being configured to reside below a patellar tendon and to elevate and / or tilt the patellar tendon. The inferior portion is configured to be seated in proximity to a tibia. The anterior portion is between the superior portion and the inferior portion. The anterior portion is placed in proximity to a patella. In one aspect, the method includes inserting the implant beneath the patellar tendon and between the patella and a position at which the patellar tendon is affixed to the tibia. In this aspect, the method also includes affixing the implant.

Description

BACKGROUND OF THE INVENTION[0001]Problems of the patella-femoral joint are a common cause of knee pain. The pain may arise from issues such as poor alignment of the patella or from cartilage breakdown (chondromalacia or arthritis) behind the patella or on the opposing articular surface of the femoral groove (trochlea). Conventional surgical options for treating patella-femoral pain caused by malalignment, chondromalacia or arthritis may include realignment of the patella. For example tracking of the patella may be changed by tilting the patella or by moving the patella to one side or the other. Moving the patella forward (i.e., anteriorly) through a surgical procedure provides another conventional option for treating these conditions. This conventional technique is thought to decrease force across the patella-femoral joint and thus diminish the pain arising from excess force against a worn-out patellar or trochlear cartilage.[0002]Although available, surgical options to realign the ...
