Knee Replacement Exercise Equipment

Most PTs ask TKR patients to do heel slides, terminal extension stretches, quad sets, and gentle straight-leg raises every day. The core home toolkit is a heel slide board for smooth flexion reps, a foam roller (like KneEXT) for terminal extension, and a non-elastic yoga strap to assist heel slides and for hamstring and calf stretches.

You start gentle exercises the same day or the day after surgery. Your surgeon will usually give you discharge papers with instruction, in the hospital exercises are performed with PT guidance. Daily heel slides, ankle pumps, quad sets, and short walks begin within 24–48 hours. Outpatient PT typically starts 5–10 days post-op, and home exercise continues 3–6 times per day for the first 6 weeks.

A heel slide board isn't medically required, but it makes the #1 prescribed TKR exercise — heel slides for knee flexion — noticeably smoother and less painful. A 3/16" MDF board's low-friction surface lets your heel glide without snagging on bedsheets or carpet, so you can focus on the stretch rather than fighting the surface.

Everyone is different, but most patients walk with a walker right away, transition to a cane by week 3–4, and walk independently by week 6–8. A near-normal gait usually returns by 10–12 weeks if you stay consistent with daily PT exercises. Full strength and confidence can take 6–12 months.

Weeks 1–2 focus on swelling control, ankle pumps, and basic heel slides. Weeks 3–4 push flexion past 90° and prioritize full extension. Weeks 5–6 add closed-chain strengthening, mini-squats, and longer walks. The goal by week 6 is roughly 120° of knee flexion and 0° of full extension.

A heel-cutout foam roller is a tool PTs use for terminal knee extension — the hardest milestone for many TKR patients. You place the roller under your ankle so the heel hovers in the cutout and gravity helps the knee drop into full extension. EquipCore's KneEXT is purpose-built for this purpose.
