How Long Does Physical Therapy Take? Visits and Weeks by Condition

By Dr. Rob Letizia, PT, DPT | Spectrum Therapeutics of NJ - Wayne, NJ

Almost everyone asks it at the first visit, and almost no website answers it: how long is this going to take? Not how long the injury takes to heal — how many weeks you will actually be coming in, and how many visits that adds up to. Below are the real numbers we use at Spectrum Therapeutics in Wayne, NJ, broken out by condition, along with the check that tells you whether a course of therapy is working before you have spent two months on it.

How long does physical therapy take?

For most orthopedic problems, a course of physical therapy runs 6 to 12 visits across 4 to 8 weeks. Simple, recent problems finish faster — 4 to 6 sessions. Chronic or complex ones typically need 8 to 12 sessions over 6 to 10 weeks. Post-surgical rehabilitation is a different scale entirely and is measured in months, not weeks.

Two things move that number more than anything else: whether there was surgery, and how long the problem has been going on before you start. An acute injury seen early is the cheapest, fastest case there is. The same injury left for eight months is not the same case.

How many physical therapy visits will I need, by condition?

These are the courses of care published on our own condition pages, not industry averages.

Condition	Typical course	Frequency
Non-surgical knee (meniscus, patellar tendinopathy, IT band, osteoarthritis)	6–10 visits over 4–8 weeks	2x per week
After a knee replacement	8–16 weeks	2–3x per week
Non-surgical shoulder (cuff tendinopathy, impingement, AC sprain, biceps tendinopathy)	8–12 visits over 4–8 weeks	2x per week
Frozen shoulder	24–48 visits over 12–16 weeks	2–3x per week
After a rotator cuff repair or shoulder replacement	20–40 visits over 4–9 months	Tapers across the phases
Non-surgical hip (impingement, labral tear, trochanteric bursitis, hip flexor strain)	6–12 visits over 4–8 weeks	1–2x per week plus daily home work
After a hip replacement	20–30 visits over 10–12 weeks	Tapers across the phases
Neck and cervical spine	6–10 visits, with noticeable change usually by visit 3–4	2x per week
Mid-back and thoracic spine	4–8 sessions over 3–6 weeks	2x per week
Acute lower back pain	4–8 sessions	2x per week
Chronic low back pain or disc herniation	8–16 sessions over 2–3 months	2x per week, tapering
Foot and ankle	8–16 visits over 6–12 weeks; a simple sprain or early plantar fasciitis, 6–8 visits	2x per week
After ankle or foot surgery	8–16 weeks	Tapers across the phases

Your own number sits inside those ranges based on severity, how long you waited, and what you need to get back to. A retired golfer and a roofer with the same shoulder do not get the same discharge date.

How long does physical therapy take for frozen shoulder?

Frozen shoulder is the longest course in the table, and it is the one people most often underestimate. Typical dosing is 2 to 3 times per week for 12 to 16 weeks, which comes to 24 to 48 visits, and most patients are discharged inside that 12 to 16 week window.

That sounds like a lot until you compare it with the alternative. Left untreated, frozen shoulder commonly runs 18 months to 3 years. The reason the course is long is that the problem is the joint capsule itself, and capsular tissue changes slowly and only under repeated, specific load. There is no version of this condition that resolves in six visits, and a plan that promises one is not treating the capsule.

Surgery — manipulation under anesthesia or arthroscopic capsular release — is only considered after six or more months of failed conservative care. See our frozen shoulder care in Wayne, NJ page for how the stages are managed.

How many weeks of physical therapy after shoulder surgery?

After a rotator cuff repair or a shoulder replacement, plan on 20 to 40 visits spread across 4 to 9 months. That is not 40 visits of the same thing: the early weeks are protective and passive, the middle is motion, and the strengthening that most people think of as "rehab" does not start until the repair can take load.

The frequency tapers as you go. Early on you are in often and doing very little by yourself; later you are in rarely and doing a great deal at home. If your visit schedule is not thinning out by the later phases, ask why.

How long is physical therapy after a knee replacement?

After a total knee replacement, the course is 2 to 3 sessions per week for 8 to 16 weeks. Knee replacements are front-loaded in a way most surgeries are not: the range of motion you are going to keep is largely decided in the first twelve weeks, which is why the visit frequency is high early and why missed weeks at the start are expensive.

Rehabilitating a knee replacement is therefore a two-to-four month commitment of clinic time, inside a recovery that keeps improving for a year. Those are two different clocks and people routinely confuse them. Our knee rehabilitation in Wayne, NJ page sets out the non-surgical courses as well.

How soon after surgery should you start physical therapy?

Sooner than most people expect, and the exact day belongs to your surgeon. Many orthopedic protocols start therapy within days of the operation, and some start it the same week, because early protected motion is what prevents the stiffness that is far harder to treat later.

What differs between procedures is not whether you start early but what you are allowed to do when you do. After a knee replacement, early work is aggressive about motion. After a cuff repair, the early weeks are deliberately passive and protective, because the tendon is healing to bone and the repair cannot take load yet. Your surgeon's protocol overrides any general timeline, including this one.

How often should you go to physical therapy?

Standard dosing across most of our conditions is twice a week, moving to two or three times a week after surgery, then tapering. But frequency is only half of the dose.

The model we actually run is what we call the 2-Plus-5 Hybrid: one to two in-clinic sessions a week, plus home work on the other days. The clinic sessions are where the hands-on work, the loading decisions and the progressions happen. The other five days are where the tissue actually adapts. A patient doing two visits a week and nothing in between is getting roughly a third of the programme, and it shows up as a course of care that stretches on without finishing.

How do I know if physical therapy is working?

You should not have to wait until the end of a course to find out. Most patients report meaningful change within the first 3 to 6 visits — and that includes people who have had unsuccessful physical therapy somewhere else before.

That gives you the 6-Visit Check, which is the rule we hold ourselves to: by the sixth visit there should be a measurable change in something — pain, range, strength, sleep or function. If there is not, the plan changes. Not the patient, not the effort level: the plan. Something in the diagnosis, the dose or the technique is wrong, and another six visits of the same thing will not fix it.

"Measurable" is the load-bearing word. It means a number someone wrote down at the start and re-measured — degrees of motion, a strength grade, how far you walked, how many times you woke up. A course of care with no measurements at the start cannot pass or fail this check, which is its own kind of answer.

When a course of physical therapy should stop and get re-checked

Most of the time a stalled course means the plan needs changing. Occasionally it means the problem is not the one being treated, and that needs a doctor rather than more sessions.

Stop and seek medical review, rather than booking more visits, if you have:

• Pain that is steadily worsening week over week despite therapy, rather than plateauing
• Numbness, weakness or pins and needles that is spreading rather than receding
• Any loss of bowel or bladder control, or numbness in the saddle area — this is an emergency, go to the emergency room
• Fever, chills, or night pain that wakes you consistently and is not related to position
• Unexplained weight loss alongside the pain
• A joint that becomes hot, red and swollen
• After surgery: a sudden loss of motion you had already gained, or a pop followed by new weakness — call your surgeon

Started with an AI assistant? Bring the plan in.

People increasingly arrive having already asked ChatGPT, Gemini or Claude how long their rehabilitation should take, and the general shape of those answers is usually reasonable. The gap is always the same: an assistant cannot measure anything. It cannot tell you whether your shoulder has lost passive external rotation or just hurts, and that distinction changes a 10-visit course into a 30-visit one.

Bring the plan and the timeline you were given. We will measure the joint, tell you which parts hold up, and give you a visit count with a number attached to it rather than a range copied off the internet.

How many visits will insurance cover?

Visit limits are set by the individual plan, and our billing team verifies yours and explains any out-of-pocket cost before treatment starts — before, not after the course is underway. If your plan caps visits below what the condition needs, we would rather build the plan around that from day one than run out of authorised visits in week six.

On referrals: New Jersey has direct access, so for most plans you can start physical therapy without seeing a doctor first. Medicare is the exception. Any Medicare plan requires a doctor's prescription before physical therapy — that includes every Medicare Advantage plan and AARP Medigap, with no exceptions. If you have Medicare in any form, get the script first; see our Medicare physical therapy page.

Spectrum Therapeutics treats patients at our Wayne, NJ clinic and across Northern New Jersey, including Totowa, Little Falls, Fairfield and the surrounding Passaic County communities. Every session is one-on-one with Dr. Rob Letizia, which is the reason our courses of care tend to run at the shorter end of the ranges above: the hands-on time is not divided between three patients and an aide.

If you want the specifics for your own problem, the region pages carry them: knee, shoulder, hip, neck, lower back and foot and ankle.

Frequently asked questions

How long does physical therapy take to work?

Most patients notice a change within the first 3 to 6 visits. That is change, not resolution — the full course for most orthopedic conditions is 6 to 12 visits across 4 to 8 weeks.

How long is physical therapy for frozen shoulder?

Typically 2 to 3 sessions per week for 12 to 16 weeks, which is 24 to 48 visits. Most patients are discharged within that window. Untreated, frozen shoulder commonly lasts 18 months to 3 years.

How many weeks of physical therapy after rotator cuff surgery?

20 to 40 visits across 4 to 9 months. The early weeks are protective and passive, motion comes next, and strengthening starts only once the repair can take load.

How long is physical therapy after a total knee replacement?

2 to 3 sessions per week for 8 to 16 weeks. Motion is largely decided in the first twelve weeks, so early frequency matters more here than in almost any other rehabilitation.

How long does it take to rehab a knee replacement?

The clinic course is 8 to 16 weeks. The recovery itself keeps improving for about a year, which is a separate and longer clock from the one your visit schedule runs on.

How soon after surgery should physical therapy start?

Often within days, and the exact day is your surgeon's call. Early protected motion is what prevents the stiffness that is much harder to treat later. What changes between procedures is what you may do, not whether you start.

How often should I go to physical therapy each week?

Twice a week is standard for non-surgical conditions, and two to three times a week after surgery, tapering as you progress. The home programme on the other days is not optional extra credit; it is most of the dose.

What if I finish a course of physical therapy and I am not better?

Apply the 6-Visit Check earlier next time. If nothing measurable changed in the first six visits, the plan should have changed then. A second opinion that starts with actual measurements is usually worth more than another block of the same sessions.

Do I need a referral for physical therapy in New Jersey?

For most insurance plans, no — New Jersey direct access lets you start without a physician referral. Any Medicare plan, including Medicare Advantage and AARP Medigap, requires a doctor's prescription first.
