The first few steps out of bed in the morning tell you a lot. If a hip or knee feels stiff and achy for ten or fifteen minutes, then loosens up once you get going, that pattern has a name.
It is one of the most recognizable signs of osteoarthritis in the hip or knee.
If you are a senior who has been told to rest the joint and take it easy, this guide explains why physical therapists usually say close to the opposite. If you are a caregiver watching someone move a little less each month, the exercises below are the ones a therapist is most likely to start with.
Quick Answer: Why Exercise Comes Before Rest
For hip and knee osteoarthritis, guided exercise is considered a first-line treatment, meaning it is one of the first things tried rather than a last resort after medication or surgery. The goal is to strengthen the muscles around the joint so they carry more of the load and the joint surface carries less.
The exercises that do the most work are usually unglamorous ones: quadriceps strengthening for the knee, hip abductor strengthening for the hip, and gentle range-of-motion movement for both. What gets avoided is high-impact loading, especially during a flare.
What Hip and Knee Osteoarthritis Actually Is
Osteoarthritis is a change in the cartilage that cushions the ends of the bones inside a joint. As that cushion thins, the bones move with less padding between them, and the whole joint gets involved: the lining, the surrounding bone, and the muscles that control the movement.
The hip and the knee are two of the most commonly affected joints, along with the hands, neck, and lower back.
Hip osteoarthritis often shows up as pain in the groin or the front of the thigh, plus trouble putting on socks or getting out of a car. Knee osteoarthritis tends to announce itself on stairs, on hills, or when standing up from a low chair.
For a wider view of the different forms of arthritis and how they are handled day to day, our overview of arthritis types, symptoms, and everyday management covers that ground.
Why Resting the Joint Usually Backfires
Resting a painful joint feels like the sensible thing to do, and for a day or two it can be. The trouble starts when a day or two becomes a habit.
Muscles lose strength quickly with disuse in older adults. Weaker thigh and hip muscles mean the joint absorbs more force with every step, which raises pain, which encourages more rest.
In physical therapy, the most common finding in a new hip or knee osteoarthritis patient is not a dramatic X-ray. It is a noticeably weak quadriceps or a weak set of hip muscles on the painful side, built up over months of understandable avoidance.
The encouraging part is that this cycle runs in both directions. Strength that was lost through avoidance can usually be rebuilt through steady, appropriately dosed work.
Everyday Moments Where Hip and Knee Osteoarthritis Shows Up
- Standing up from a soft couch or a low toilet seat, especially the first attempt
- Going down stairs, which loads the knee harder than going up
- Getting in and out of the car, where the hip has to rotate and bend at the same time
- Stiffness after sitting through a movie, a church service, or a long car ride
- Putting on socks, shoes, or reaching down to clip toenails
- The last third of a grocery store trip, when the joint has had enough
Caregivers often spot these before the senior mentions them. A parent who starts pushing off the armrests to stand, or takes the elevator instead of one flight of stairs, is telling you something useful.
The Exercises Physical Therapists Use Most
These are the workhorses of a conservative osteoarthritis program. A therapist will pick from them based on which joint hurts, how much it hurts, and what you can already do.
- Quad sets (knee): Sitting with the leg straight, tighten the thigh and press the back of the knee down into a rolled towel. Hold 5 seconds, 10 repetitions, two or three times a day. This is often the very first exercise given because it builds strength without moving the sore joint much.
- Straight leg raise (knee and hip): Lying on your back with the other knee bent, tighten the thigh and lift the straight leg about 12 inches. 10 to 15 repetitions, 2 sets, most days.
- Short-arc quad (knee): With a rolled towel or foam roll under the knee, straighten the knee fully, hold 3 seconds, then lower slowly. 10 to 15 repetitions, 2 sets.
- Side-lying hip abduction (hip and knee): Lying on your side, lift the top leg 12 to 18 inches with the toes pointed forward, not up. 10 to 15 repetitions per side, 2 sets. Hip abductor strengthening helps knee osteoarthritis too, because weak hip muscles let the knee drift inward under load.
- Standing hip abduction: Holding a counter, lift one leg out to the side without leaning. 10 to 15 repetitions per side. Good for anyone who cannot get down to the floor comfortably.
- Bridges (hip): Lying on your back with knees bent, lift the hips until the body makes a straight line from knees to shoulders. Hold 3 to 5 seconds, 10 repetitions.
- Sit-to-stand (both): From a firm chair, stand and sit with the arms crossed if you can do it safely. 8 to 10 repetitions, 2 to 3 sets, three days a week. This one carries over directly to real life.
- Heel slides and gentle knee bends (range of motion): 10 to 15 slow repetitions once or twice daily to keep the joint moving through its full available range.
- Low-impact cardio: Stationary cycling with light resistance, water exercise, or walking in several short bouts. Ten minutes at a time is a fine place to start, building toward the general adult target of about 150 minutes of moderate activity a week.
Water-based exercise deserves a special mention for anyone with a lot of pain. The water takes weight off the joint while still giving the muscles something to push against, which lets people work harder than they can on land.
Strength changes in this population usually take 8 to 12 weeks of consistent work, not two weeks. That timeline is worth knowing up front so nobody quits at week three thinking it did not work.
One important distinction: everything above is about managing the joint you still have. If a hip or knee has already been replaced, the plan is different and follows a surgical protocol, which we cover separately for rehabilitation after a knee replacement and for recovery after a hip replacement.
What a Physical Therapist Will Typically Check
An evaluation for hip or knee osteoarthritis is mostly a measuring exercise. The therapist is trying to find out which specific weakness or restriction is driving your particular pain.
- Joint range of motion, measured with a goniometer, comparing the painful side to the other side
- Quadriceps and hip abductor strength, tested individually rather than guessed at
- How you stand up from a chair, including whether you push off with your arms and which way the knee travels
- Walking pattern, including limping, shortened steps, and how far you can go before pain climbs
- A functional test such as the 30-Second Chair Stand or the Timed Up and Go, which gives a number to compare against later
- Balance and fall history, since a painful hip or knee changes how you catch yourself
- Which specific daily activities have gotten harder, in your own words
Caregivers can help here more than they realize. Bringing concrete examples, like “she stopped going down to the basement in March,” gives the therapist information that a twenty-minute clinic visit cannot produce on its own.
What NOT to Do
- Do not do high-impact loading during a flare. Running, jogging, jumping, rope skipping, and high-impact aerobics all involve both feet leaving the ground, and that force lands on an already irritated joint.
- Do not do deep squats, deep lunges, or full knee bends past about 90 degrees while a knee is painful, unless a therapist has cleared that range for you.
- Do not push through sharp, catching, or stabbing pain inside the joint. Muscle soreness the next day is normal and expected, but joint pain that spikes is a signal to reduce the load.
- Do not stop moving entirely during a flare. Drop back to range-of-motion work and gentle water or seated exercise, then rebuild once the flare settles.
- Do not judge the program by how the joint feels during the first week.
- Do not assume a bad X-ray means exercise is pointless. Two people with nearly identical imaging can have very different pain levels and very different function.
A rule of thumb many physical therapists use: if the joint hurts more two hours after exercise than it did before, and that extra pain is still there the next morning, the dose was too high. Cut the repetitions roughly in half next session rather than stopping altogether.
Frequently Asked Questions
Will exercise wear my joint out faster?
Appropriately dosed, low-impact exercise is not what wears a joint out. Guidelines treat exercise as a core treatment for osteoarthritis precisely because stronger muscles reduce the load the joint itself has to absorb.
What are the best hip osteoarthritis exercises to avoid?
The ones to skip are high-impact activities where both feet leave the ground, deep hip flexion that pinches in the groin, and heavy twisting or pivoting sports. Deep squats and aggressive stretching into painful ranges are also common irritants.
Can exercise help me put off a joint replacement?
For some people it does, and for others surgery is still the right answer eventually. Either way, going into a replacement with stronger hip and thigh muscles tends to make the recovery afterward go more smoothly.
How often should these exercises be done?
Most home programs run strengthening exercises three days a week with rest days between, plus daily range-of-motion work and low-impact walking or cycling. A therapist adjusts that based on how the joint responds.
Final Thoughts for Adults Over 50
Osteoarthritis is common, and being common has made people fatalistic about it. The evidence points the other way: the strength around the joint is something you can still change, at almost any age.
If you are a senior, the most useful next step is getting your quadriceps and hip strength actually measured rather than guessed at, so the exercise you do is aimed at your specific weak point instead of a generic handout.
If you are a caregiver, watch for the quiet withdrawals: the stairs skipped, the walk shortened, the errand handed off. Those changes happen gradually enough to miss, and they are usually easier to reverse early than after a year of avoidance.
Medical Disclaimer
This article is for general education and is not a substitute for medical advice. Talk with a doctor or physical therapist before starting a new exercise program for hip or knee osteoarthritis, especially if you have had a joint replacement, a recent injury, or a heart condition.
Stop exercising and seek medical attention for sudden severe joint pain, a joint that gives way or locks, significant swelling, redness and warmth over the joint, or chest pain and severe dizziness during activity.
