Exercise after hip or knee replacement: what recovery really looks like.

By Francisco, ACE-certified personal trainer · October 2026 · 9 min read

Ask people what they actually want after a hip or knee replacement, and it's rarely “a perfect joint.” Researchers in Sweden who spent a year interviewing knee replacement patients found what people wanted was a silent knee: one that didn't hurt, didn't get in the way, and that they could finally stop thinking about. The surgery is very good at fixing the joint. What it doesn't fix is the habit of protecting it, or the caution that builds after months of being careful. That part is up to you, and it's where the right exercise plan makes the difference between a joint you forget about and one you keep managing for years. This guide covers what recovery actually looks like week by week, why hips and knees recover differently, and the strength work that closes the gap between finishing physical therapy and feeling like yourself again.

How long does recovery really take?

Short answer: most people resume light daily activities within 3 to 6 weeks, but full recovery takes much longer: often several months for a hip and up to a year for a knee.

The most misunderstood number is “6 weeks.” That's typically when hip precautions ease up and early physical therapy winds down, not when healing is finished. Soft tissue around the joint keeps strengthening for months after that, which is exactly why strength work doesn't stop when physical therapy does.

Why knees usually take longer than hips

People who've had both joints replaced consistently say the knee was harder: more painful physical therapy and a longer road back to feeling normal. The research backs that up. Knee replacement patients report meaningfully more dissatisfaction than hip patients, with roughly 15 to 20% of knee replacement patients still not fully satisfied with their outcome a year or more out.

A big part of the difference is range of motion. After knee replacement, the American Academy of Orthopaedic Surgeons notes most patients need at least 90 degrees of knee bend for basic daily activities like stairs and sitting in a regular chair, and most patients ultimately achieve more than 110 degrees with consistent exercise. Hip replacement doesn't have an equivalent motion goal to fight for, which is part of why it tends to feel more straightforward.

If you're having a knee done, plan for a longer, more demanding recovery. That way a hard week reads as normal, not as something going wrong.

A realistic recovery timeline

Every surgeon and every body is different, so follow your own team's plan over any general guide. This is roughly what to expect:

Days 1 to 3: Most patients stand and take their first steps with a walker the same day or the next morning, and a physical therapist teaches safe transfers before discharge.

Weeks 1 to 2: Short, frequent walks, basic exercises like ankle pumps and gentle knee bends, and more rest than you'd expect. Most patients describe this as the hardest stretch, before things noticeably turn a corner.

Weeks 2 to 6: Walking distance grows, strength work begins in earnest, and most people move from outpatient physical therapy toward independence. Hip precautions, where they apply, are often still in place through this window.

Weeks 6 to 12: Many patients are cleared for more demanding activity: a stationary bike, light strength training, and for some, a return to low-impact sport.

Months 3 to 12: This is where real strength, balance and confidence get rebuilt, and where a knee can stay swollen or stiff for months, which is normal rather than a setback.

How do you know if you're overdoing it?

Short answer: ongoing swelling, deep aching or burning pain that's hard to settle, or soreness that's worse the next day instead of easing.

A simple way to progress safely: increase your walking distance by one small step at a time, and let yesterday's recovery tell you what today should look like. If you're sore and flat the next day, that was too much; back off and repeat the shorter distance before adding more. If you feel good, add a little more tomorrow. Move, rest, move, rest, move.

Mild soreness that eases with rest and ice, muscle fatigue after exercises, and morning stiffness are all normal. Swelling that keeps building, pain that's worse every day rather than better, or deep pain that's hard to control are signs to call your physical therapist or surgeon rather than push through.

Hip precautions you may not need forever

If you had hip surgery, you likely heard the classic rules: no bending past 90 degrees, no crossing your legs, a pillow between your knees at night. They were standard advice for decades, meant to prevent the new joint from dislocating, and restrictions depend heavily on how your surgeon reached the joint: posterior approach surgery typically comes with more precautions than anterior approach.

A 2020 systematic review in Acta Orthopaedica, covering 6,900 patients across seven studies, found no meaningful difference in dislocation rates between patients who followed strict precautions and patients who didn't: 2.2% versus 2.0%. For most patients today, dislocation risk comes more from the specific surgery and implant than from everyday movements like bending to tie a shoe.

What this doesn't mean: ignore your surgeon. Precautions still matter in early healing, especially after a posterior approach, and your surgeon's specific protocol is written for your anatomy and procedure, not a general average. What it does mean: the old blanket fear of movement isn't as well supported as it used to be, and it shouldn't follow you for years after you've been cleared.

The exercises that close the gap

Physical therapy usually ends once you can handle daily life safely, often well before you feel confident on a golf course, a pickleball court or a hiking trail. That gap between cleared and confident is where many people quietly stall. Closing it takes progressive strength work, not just maintenance:

• Glute bridges: rebuild the hip and knee extensors that power every step
• Clamshells with a light band: target the hip abductors that stop a lingering limp
• Sit-to-stands from a firm chair: rebuild the strength to get up without using your arms
• Step-ups onto a low box: restore the strength and confidence stairs require
• Stationary bike: builds knee range of motion and cardiovascular fitness with minimal impact
• Single-leg balance near a counter: rebuilds trust in the joint on uneven ground

If your surgery is still ahead, the research on prehabilitation, meaning exercise before surgery, is genuinely encouraging: patients who complete exercise-based prehab show measurably better walking speed, stair climbing and chair-rise ability afterward. Our strength and balance training is built around exactly this kind of individualized, pre- and post-surgical progression.

Getting back to golf, pickleball and the things you love

Short answer: most active people do return to their favorite low-impact activities, though high-impact sports like running and jumping put considerably more stress on a new joint.

The data is genuinely encouraging. In one study of hip replacement patients, 91% who played sport before surgery returned to sport afterward, more than half within 1 to 3 months. A large recent study of knee replacement patients found a median return-to-sport time of 12 weeks, with 90% of those returning doing so within about six months.

Walking, swimming, cycling, golf and dancing are realistic goals for most patients. For pickleball specifically: ease back in with dinking before full games, and once you're playing, the same rule applies to every player regardless of surgery history: never backpedal for a lob.

Always get your surgeon's clearance before returning to any sport, and build back gradually rather than jumping straight to your old intensity.

When to call your doctor instead of your trainer

Contact your surgeon right away if you notice:

• New or increasing swelling in your thigh, calf, ankle or foot, especially with calf pain or tenderness unrelated to your incision
• Persistent fever above 100°F, chills, or increasing redness, warmth or drainage at the incision
• Sudden, severe hip or groin pain, a leg that looks shorter or turned in or out, or an inability to bear weight
• Joint pain that keeps increasing with both activity and rest, rather than improving
• Sudden shortness of breath or chest pain: call 911. These can signal a blood clot that has traveled to the lungs, and they need emergency care, not a wait-and-see approach.

Ready for life after physical therapy?

The surgery already did the hard part. What comes next is rebuilding strength, trust in your own body, and the daily habits that keep a new joint working for decades.

If you're in the East Bay and have finished physical therapy, our private strength and balance training picks up where PT leaves off, coordinated with your surgeon's guidelines and built around what you want to get back to.
