PT Adherence After Orthopedic Surgery: What Practices Can Do
The American Physical Therapy Association reports that physical therapy adherence for orthopedic rehabilitation ranges from 40% to 65% depending on the procedure and measurement method. Non-adherence after knee replacement, ACL reconstruction, and rotator cuff repair is associated with measurably worse functional outcomes at 6 and 12 months.
Where and Why Patients Drop Off
The highest dropout period is weeks 4 to 8 post-surgery, when acute pain has subsided and patients perceive that they are 'healed.' Functional recovery at this stage is typically only 40% to 60% complete.
A 2019 study in the Journal of Orthopaedic and Sports Physical Therapy found that the top 3 barriers to PT adherence were: cost and insurance limitations (38%), transportation and scheduling (27%), and pain during exercises perceived as harmful (22%).
Home exercise program (HEP) compliance is even lower than in-clinic attendance. A systematic review in Physiotherapy Theory and Practice found that only 30% to 50% of patients perform their HEP as prescribed.
Patients who do not understand the purpose of specific exercises are more likely to skip them. 'Do 3 sets of 10 leg raises' with no explanation of why leads to lower compliance than 'This exercise rebuilds the quadriceps strength you need to walk without a limp.'
Pre-Surgical Expectation Setting
Patients who receive detailed recovery timelines before surgery have better PT adherence than those who learn about the rehab process after the procedure. Set expectations at the pre-op visit, not the post-op visit.
Be specific about the work involved: 'After knee replacement, you will attend PT 2 to 3 times per week for 6 to 12 weeks. You will also do exercises at home daily. The first 2 weeks will be uncomfortable. By week 6, most patients walk without assistance.'
Address the 'good enough' trap directly: 'At week 4, you will feel much better, but your knee will only be at about 50% of its potential. The second half of PT is what determines whether you get a good result or a great one.'
Provide the full cost estimate for PT upfront, including copays and number of expected visits, so patients can plan financially rather than dropping out due to unexpected costs.
During Rehab: Tracking and Reinforcement
Milestone-based progress tracking gives patients concrete evidence that PT is working. 'You started at 60 degrees of flexion, and you are now at 95 degrees' is more motivating than 'Keep doing your exercises.'
Connect outcomes to activities the patient cares about: 'At 110 degrees of flexion you will be able to ride a bike again' or 'At this strength level you can return to golf.'
Identify dropout risk early. Patients who miss 2 or more consecutive sessions are unlikely to return without direct outreach. A phone call from the surgical team (not just the PT clinic) carries more weight.
For patients who cannot attend in-person PT due to cost or travel, discuss alternatives: telehealth PT visits, reduced-frequency plans with heavier HEP focus, or community-based exercise programs supervised by a PT.
For knee replacement, patients who complete their full PT protocol achieve an average of 115 to 125 degrees of flexion versus 95 to 105 degrees for non-completers, based on data from the American Association of Hip and Knee Surgeons. For ACL reconstruction, incomplete PT is associated with higher re-tear rates and persistent instability at return-to-sport testing.
How should I handle patients who want to stop PT early?
Have an honest conversation about where they are versus where they could be. Show them their current measurements against the target range. If cost is the barrier, discuss reduced-frequency alternatives. Document the conversation and the patient's decision, including the risks you communicated.
Does telehealth PT work for orthopedic rehab?
A 2022 systematic review in the Journal of Telemedicine and Telecare found that telehealth PT produced equivalent outcomes to in-person PT for knee replacement and ACL rehab in most functional measures. It does not replace hands-on manual therapy but can supplement in-clinic visits and improve adherence for patients with transportation barriers.
