BACKGROUND: Swimming is commonly recommended as postoperative rehabilitation following total hip arthroplasty (THA) and total knee arthroplasty (TKA). So far, in vivo hip and knee joint loads during swimming remain undescribed. METHODS: In vivo hip and knee joint loads were measured in 6 patients who underwent THA and 5 patients who underwent TKA with instrumented joint implants. Joint loads, including the resultant joint contact force (FRes), torsional moment around the femoral shaft axis or the tibial axis (MTors), bending moment at the middle of the femoral neck (MBend), torsional moment around the femoral neck axis (MTne), and medial force ratio (MFR) in the knee, were measured during breaststroke swimming at 0...
