The PNF Group followed a 6-week PNF exercise program starting four weeks post-surgery. The PNF\u2009+\u2009FV Group followed the same PNF program combined with FV applied to the rectus femoris and vastus medialis. The control group received instructions for a home-based exercise program. Pain (Numeric Pain Rating Scale; NPRS), knee range of motion (ROM), functional ability (Knee Injury and Osteoarthritis Outcome Score, KOOS), joint position sense (JPS), postural sway (force platform), and balance (Timed Up-and-Go; TUG test, Berg Balance Scale; BBS) were evaluated at baseline, six weeks, and six months post-intervention. A two-way repeated measures ANOVA analysis was applied with significance set at p\u2009&lt;\u2009.05.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The PNF\u2009+\u2009FV group showed significant improvements compared to the control group in NPRS, KOOS, TUG, BBS, displacement parameters, and absolute error scores (p\u2009&lt;\u2009.05). The PNF\u2009+\u2009FV group showed earlier improvements compared to the PNF group, indicating faster adjustments due to the combined effect of PNF and FV. Additionally, the PNF\u2009+\u2009FV group showed greater improvement in TUG, BBS, KOOS sport, anterior-posterior displacement distance, and absolute error scores at 25\u00b0 compared to the PNF group (p\u2009&lt;\u2009.05). PNF exercises improved knee ROM (p\u2009&lt;\u2009.05) with no additional effect from FV.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>A 6-week protocol combining PNF exercises and FV significantly improved balance, knee joint position sense, knee functional ability, and pain intensity in older adults after TKA due to osteoarthritis.
