Recurvatum deformity complicating performance of total knee arthroplasty. A brief note

Department of Orthopaedic Surgery, Johns Hopkins University School of Medicine, Baltimore.
Recurvatum may be the rarest deformity complicating the performance of
total knee arthroplasty. The cases of four patients--two who had a primary
total knee arthroplasty and two, a revision--are described, as well as the
measures that are needed to correct the malalignment while avoiding the use
of a highly constrained prosthesis. The principal measure that is necessary
is the positioning of one of the attachments of one or both collateral
ligaments on the femur in order to recreate the normal tightening action as
full extension of the knee is achieved.
