The intervention group completed four\u2009weeks preoperative and four\u2009weeks postoperative PRT, whereas the control group only completed four\u2009weeks postoperative PRT. Main follow-up measures were as follows: the 30-second Chair Stand Test (primary outcome), Timed Up and Go Test, walk tests, knee extensor, and knee flexor muscle strength and patient-reported outcomes. Statistical analyses were performed according to the intention-to-treat principle. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p> No significant group differences were observed for the primary outcome 30-second Chair Stand Test (4.0 repetitions versus 2.4 repetitions, P\u2009=\u20090.067) or for other functional performance outcomes. The intervention group had significantly higher weight-normalized knee extensor muscle strength (0.5 Nm\/kg versus 0.2 Nm\/kg, P\u2009=\u20090.002) and knee flexor muscle strength (0.3 Nm\/kg versus 0.2 Nm\/kg, P\u2009=\u20090.042) in the operated leg when compared to the control group. No significant group differences for patient-reported outcomes. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion:<\/jats:title><jats:p> The study supports the use of short-term high-intensity resistance training before TKA as it induces a long-lasting effect on muscle strength, while it may have no discernible effect on functional performance.
