Autologous chondrocyte implantation: current surgery and rehabilitation.

Autologous chondrocyte implantation (ACI) is a treatment option for full-thickness chondral, or osteochondral injuries that are painful, debilitating, and progressive. Goals of surgery and rehabilitation include replacement of damaged cartilage with hyaline or hyaline-like structure, maintained durability to withstand knee intraarticular forces over time with a productive level of function, and restoration of the normal surface congruity of the joint. Intermediate and long-term results are promising in terms of clinical improvement and durability using ACI.

Variability of landmark identification in total knee arthroplasty.

Virtual reality is new technology that is finding application in many facets of orthopaedics. We will describe an application of virtual reality in orthopaedic research. Component placement in total knee arthroplasty depends on identification of anatomic landmarks about the knee.
