Utilizing Unicompartmental Knee Arthroplasty for More than One Compartment
Unicompartmental knee arthroplasty can involve any of the three knee compartments, namely, the medial, lateral, or patellofemoral, and is an excellent option for patients with relative preservation of the remaining two compartments. Traditionally, total knee arthroplasty has been the surgical treatment of choice for patients with symptomatic arthritis involving more than one compartment. There is evidence that modular bicompartmental knee arthroplasty, replacing two compartments with two separate unicompartmental implants and preserving the natural anatomy of the third compartment is a reasonable alternative to total knee arthroplasty in these patients. The purpose of the current discussion is to present the available evidence regarding bicompartmental knee arthroplasty.
