The Hauser procedure used to be performed for recurrent dislocation of the patella.
Technique of Hauser Procedure
The Hauser procedure involved cutting off the tibial tubercle with attached patellar tendon and simply moving it medially and fixing it in the new position. This procedure is no longer done because it turned out that many patients had nasty complications. The procedure is one of several distal realignment procedures for realigning the patella in its underlying groove.
