Key Takeaways
- A 2022 JOSPT review of 100 randomized trials found surgery offered no meaningful advantage over nonsurgical treatment for the majority of musculoskeletal conditions
- Patients who start PT within 2 days of injury recover in a median of 14 days versus 28 days for those who wait 13+ days
- Physical therapy costs approximately 75% less than surgical intervention for low back pain and avoids the risks of anesthesia, infection, and prolonged recovery
- All 50 U.S. states now allow direct access to physical therapy without a physician referral, saving patients $1,500 to $1,800 per episode
- Certain red flags require immediate orthopedic evaluation: displaced fractures, complete tendon ruptures with functional loss, progressive neurological deficits, and signs of infection
Walking into a doctor's office with a painful shoulder, a stiff knee, or a back that won't cooperate usually leads to one question: do I need surgery, or can physical therapy fix this? The answer matters because the two pathways produce dramatically different costs, recovery timelines, and long-term outcomes.
We use objective testing protocols to determine exactly where each patient falls on that spectrum, measuring strength deficits, range-of-motion limitations, and functional capacity before recommending a path forward. Whether you're dealing with a shoulder injury that's been lingering for months or a knee that buckled during a game, this guide breaks down when physical therapy is the right first step and when you need an orthopedic surgeon's evaluation.
Can Physical Therapy Resolve Most Musculoskeletal Injuries Without Surgery?
For the majority of musculoskeletal conditions, physical therapy produces outcomes equivalent to surgery. A 2022 JOSPT systematic review analyzed 100 randomized controlled trials covering 12,645 patients across 28 conditions at 9 body sites. The findings were clear: for 9 out of 13 conditions with pain data, 11 out of 11 with function data, and 9 out of 9 with quality-of-life data, surgery offered no clinically relevant advantage over nonsurgical alternatives.
The evidence is particularly strong for conditions that athletes commonly assume require surgery. The ESCAPE trial at 5-year follow-up found that physical therapy was noninferior to arthroscopic partial meniscectomy for degenerative meniscal tears. The KANON trial tracked ACL injury patients for 11 years and found no difference in outcomes between early surgical reconstruction and structured rehabilitation with optional delayed surgery. 30% of patients in the rehab group showed spontaneous ACL healing on MRI at 2 years.
For rotator cuff tears, a randomized trial published in the Journal of Shoulder and Elbow Surgery found no significant differences in clinical outcomes between surgical repair and physiotherapy at 12 months for small, acute tears. The 5-year FIMPACT trial confirmed that arthroscopic subacromial decompression provided no benefit over exercise therapy for shoulder impingement.
This does not mean surgery is never necessary. It means that for many conditions, a structured PT program should be the first intervention attempted, with surgery reserved for cases that do not respond.
When Should You See an Orthopedic Surgeon First?
Certain injuries bypass the "try PT first" approach entirely. Recognizing these red flags prevents dangerous delays in surgical care. The distinction is straightforward: if the structure is completely disrupted, displaced, or the injury involves progressive neurological loss, orthopedic evaluation comes first.
Displaced or unstable fractures with visible deformity, inability to bear weight, or bone protruding through skin require emergency surgical evaluation. Joint dislocations with a locked joint or compromised blood flow to the limb fall in the same category. Acute compartment syndrome, where severe pain is out of proportion to the injury with tense swelling, is a surgical emergency.
Complete tendon or ligament ruptures with total functional loss often need surgical repair, particularly in high-demand athletes. A complete Achilles rupture where you cannot push off your foot, or a complete ACL tear in a competitive athlete who needs to return to cutting and pivoting sports, typically warrants surgical discussion.
Progressive neurological deficits are another clear indicator. Worsening weakness, spreading numbness, foot drop, or any bowel or bladder dysfunction (which may signal cauda equina syndrome) require urgent evaluation. The JOSPT 2020 international framework for red flags in spinal conditions lists unexplained weight loss, history of cancer, night pain unrelieved by position change, and saddle anesthesia as indicators requiring immediate medical workup.
The key distinction for athletes: a partial rotator cuff tear with preserved function is typically a PT case. A complete rupture where you cannot raise your arm is a surgeon case. Context and objective testing determine which side of that line you fall on.
What Happens When You Delay Physical Therapy?
Every day you wait to start physical therapy after a musculoskeletal injury adds to your recovery timeline. A 2025 JOSPT Open study tracking work-related injuries found that patients who began PT within 0 to 2 days recovered in a median of 14 days with 4 visits. Those who waited 13 or more days needed a median of 28 days and 5 visits to reach the same outcomes.
The consequences extend beyond recovery time. A 2018 study in Health Services Research found that patients who saw a physical therapist first had an 89.4% lower probability of receiving an opioid prescription, a 27.9% lower probability of advanced imaging, and a 14.7% lower probability of an emergency department visit. For low back pain specifically, early PT was associated with a reduced likelihood of eventually crossing over to surgery: 21% versus 33% at one year.
These numbers matter for athletes because delayed rehabilitation allows compensatory movement patterns to solidify. Your body finds workarounds for the injury that feel functional in the short term but create secondary problems. A knee injury that goes untreated leads to hip compensation, which leads to low back strain, which leads to a situation far more complex than the original issue. Starting PT early interrupts that cascade before it builds.
How Much Does Physical Therapy Cost Compared to Surgery?
Physical therapy is substantially less expensive than surgical intervention for comparable musculoskeletal conditions. For low back pain, initial PT costs approximately $3,992 compared to $16,195 for surgery, a 75% reduction. Over a full year, the PT pathway totals roughly $11,151 versus $36,772 for a surgical pathway, representing a 50% cost difference.
Spinal fusion, one of the most common orthopedic procedures, averages $80,000 to $150,000 depending on complexity and location. A full course of physical therapy for the same condition ranges from $240 to $1,450 for 12 to 24 sessions with insurance. Even without insurance, a PT episode represents a fraction of surgical costs before accounting for anesthesia, hospital stay, post-surgical PT, and lost work time.
The financial case extends to access. As of 2025, all 50 U.S. states allow direct access to physical therapy without a physician referral. Direct access saves approximately $1,500 to $1,800 per patient compared with physician-first pathways by reducing unnecessary imaging, specialist referrals, and medication prescriptions.
This cost advantage applies to conditions where PT and surgery produce comparable outcomes. For injuries that genuinely require surgical repair, delaying surgery to save money creates worse outcomes and higher total costs. The goal is matching the right intervention to the right injury, not defaulting to the cheapest option regardless of diagnosis.
How Does a Physical Therapist Decide If You Need a Surgeon?
A qualified physical therapist evaluates your injury using objective criteria that identify both PT-appropriate cases and cases requiring surgical referral. The evaluation includes range of motion measurements, strength testing with dynamometry, special tests that stress specific structures, and functional movement assessments that reveal how the injury affects real-world demands.
If your PT finds full-thickness structural failure (a complete ligament tear confirmed by instability testing, a complete tendon rupture with no active function), progressive neurological signs, or failure to improve after 6 to 8 weeks of appropriate intervention, they will refer you to an orthopedic surgeon for further evaluation. Physical therapists are trained to screen for red flags at every visit, not just the initial evaluation.
The critical advantage of starting with a PT evaluation is that it establishes an objective baseline. If surgery does become necessary, your surgeon has pre-operative strength data, range of motion measurements, and functional scores that improve both surgical planning and post-operative rehabilitation. Patients who complete prehabilitation before surgery consistently show faster recovery and better outcomes than those who go into the operating room deconditioned.
What Role Does Nutrition Play in Avoiding Surgery?
Recovery from musculoskeletal injury depends partly on providing your tissues with the raw materials they need to repair. Two supplements stand out for supporting the kind of tissue healing that can make the difference between an injury that resolves with PT and one that progresses toward surgical consideration.
Collagen peptides at 5 to 10 grams daily, taken 30 to 60 minutes before physical therapy with vitamin C (500 to 1,000mg), support tendon and ligament repair by stimulating fibroblast activity at the injury site. A 2019 study in Nutrients found that patients supplementing with collagen experienced improved ligament healing and faster return to activity. For athletes with partial tears or tendinopathy, collagen supplementation alongside progressive loading may accelerate the structural repair that keeps surgery off the table.
Omega-3 fatty acids at 1,000 to 2,000mg of combined EPA and DHA daily create an anti-inflammatory environment that supports tissue healing. Chronic inflammation stalls the repair process and contributes to the kind of persistent pain that leads patients to consider surgical options. Taking omega-3s with meals containing fat enhances absorption.
Conclusion
The research is clear: for the majority of musculoskeletal conditions, physical therapy produces outcomes comparable to surgery at a fraction of the cost and risk. The exceptions are well-defined. Complete structural failures, displaced fractures, and progressive neurological deficits require surgical evaluation. Everything in between benefits from a structured PT assessment that establishes objective baselines and builds a criterion-based treatment plan.
We use force plate testing, dynamometry, and functional movement analysis to determine exactly where your injury sits on that spectrum. If PT is the right path, you'll know within the first few sessions. If surgery is necessary, you'll have pre-operative data that sets you up for a faster recovery on the other side.

Frequently Asked Questions
Can I go straight to a physical therapist without seeing a doctor first?
Yes. All 50 U.S. states now allow direct access to physical therapy. You can schedule an evaluation without a physician referral in most cases. Your PT will screen for red flags that require medical referral during the initial evaluation.
How do I know if my rotator cuff tear needs surgery?
Partial tears with preserved overhead function typically respond well to physical therapy. Complete tears where you cannot actively raise your arm above shoulder height, or tears that fail to improve after 8 to 12 weeks of structured rehab, usually warrant orthopedic evaluation.
Is physical therapy effective for meniscus tears?
Five-year data from the ESCAPE trial shows physical therapy is noninferior to arthroscopic meniscectomy for degenerative meniscal tears. For traumatic tears in younger patients, 59% of those who began with PT did not require surgery during the follow-up period.
How long should I try physical therapy before considering surgery?
Most orthopedic conditions show measurable improvement within 6 to 8 weeks of consistent PT. If objective measures (strength, range of motion, functional tests) plateau despite adherence to the program, that is an appropriate point to discuss surgical options with an orthopedic surgeon.
Does going to PT first delay necessary surgery?
No. A PT evaluation typically occurs within days, and if red flags or complete structural failure are identified, the referral to a surgeon happens immediately. Patients who complete prehabilitation before elective surgery actually recover faster post-operatively than those who skip PT entirely.
Bottom Line
- A JOSPT review of 100 randomized trials found surgery offered no clinically meaningful advantage over nonsurgical alternatives for the majority of musculoskeletal conditions, making physical therapy the appropriate first intervention for most injuries
- Starting PT within 2 days of injury cuts recovery time in half compared to waiting 13+ days, and PT-first patients are 89% less likely to receive an opioid prescription
- Red flags for immediate surgical evaluation are well-defined: displaced fractures, complete tendon/ligament ruptures, progressive neurological deficits, and signs of infection require orthopedic assessment before PT begins
