Longitudinal development in maximal lower limb muscle strength (Nm) for the knee extensors (A), knee flexors (B), hip adductors (C), hip abductors (D), hip extensors (E), and hip flexors (F) in the affected limb pre-surgery and at 8, 26, 52 wks post-surgery for S-THA (●) and R-THA (○) implants (mean ± 95% C.I.). # S-THA > R-THA, ∗ increase compared to 8 wks (P < 0.05).
