Utilizing reamer irrigator aspirator (RIA) autograft for opening wedge high tibial osteotomy: A new surgical technique and report of three cases.

Introduction: The lateral closing wedge high tibial osteotomy (HTO) was popularized by Coventry in the 1960s. In the 1990s the medial opening wedge osteotomy gained popularity because it could achieve greater valgus correction and it did not require dissociation of the fibula from the tibia, an important consideration when treating varus knees with lateral and posterolateral ligament deficiencies (Noyes' double-varus and triple-varus knees). However, it has the disadvantage of requiring bone graft to fill bony defects.

Arthroscopic treatment of Pipkin type I femoral head fractures: a report of 2 cases.

Pipkin type I fractures historically have required open treatment, with the potential-associated morbidity. Two cases of arthroscopic fracture fragment excision are described. These were completed using standard techniques and introducing the application of Steinman pins, through an accessory anterior portal, for capture of the fragment.
