Knee forces during activities of daily living, rehabilitation, exercise and sports after total knee arthroplasty

Director of the Orthopaedic Research Laboratories at the Shiley Center for Orthopaedic Research and Education (SCORE) at the Scripps Clinic in San Diego, California

Tibiofemoral forces are important in the design and clinical outcomes of TKA. Knee forces and kinematics have been estimated using computer models or traditionally have been measured under laboratory conditions.  Although this approach is useful for quantitative measurements and experimental studies, the extrapolation of results to clinical conditions may not always be valid.   We therefore developed a tibial tray combining force transducers and a telemetry system to directly measure tibiofemoral compressive forces in vivo.

Tibial forces were measured for activities of daily living, athletic and recreational activities, and with orthotics and braces, for 4 years postoperatively.  Additional measurements included video motion analysis, EMG, fluoroscopic kinematic analysis, and ground reaction force measurement. A third-generation system was developed for continuous monitoring of knee forces and kinematics and for classifying and identifying unsupervised activities outside the laboratory using a wearable data acquisition hardware.

This presentation will review forces measured for a wide spectrum of common and relevant activities including walking, jogging, stationary bicycling, golfing, tennis, skiing, hiking, and using exercise equipment. In addition the effect of orthotics, braces, walking aids, and gait retraining on modulating knee forces will be discussed. 
In vivo measured knee forces can be used to enhance existing in vitro models and wear simulators and to improve prosthetic designs and biomaterials as well as guide physicians in their recommendations to patients of “safe” activities following TKA.

Darryl D'Lima, MD, PhD trained as an orthopaedic surgeon in India, and as a fellow in Adult Reconstruction under Clifford W. Colwell Jr, MD at Scripps Clinic, CA .  He received his PhD in Bioengineering at UC San Diego, CA.  Dr. D’Lima’s major research interests include biomechanics of the hip and knee joints, and cartilage injury and repair. He is a grant reviewer for the NIH on Musculoskeletal, Oral & Skin Sciences study sections, and manuscript reviewer for J Orthop Res, J Biomech, J Bone Joint Surg, Clin Orthop, Arthritis & Rheum, Osteoarthritis & Cartilage, Clin Biomech, J Eng Medicine, The Knee.
