Clinical Evidence
Peer-reviewed research demonstrates the superior outcomes of PortableConnect® compared to standard physical therapy for rehabilitation after total knee arthroplasty.
Journal of Arthroplasty Study
A recent study published in the Journal of Arthroplasty has provided groundbreaking new data to support the use of PortableConnect® for outpatient rehabilitation after knee replacement surgery.
The retrospective review compared outcomes between patient groups assigned to postop rehab with either in-home, remote physical therapy (PT) using the PortableConnect system, or outpatient standard therapy protocol (STP).

270 Consecutive TKA Patients
- No statistically significant differences at baseline between groups
- Same implant, approach, and surgical protocol for all patients
- Same prehabilitation for all patients
- Progress evaluated at 2, 6, and 12 weeks
PortableConnect®: 135 Patients
- 2-5 structured sessions per day
- No additional PT prescribed
- Data monitored remotely by physical therapist
- Patients contacted if data falls outside expected parameters
Standard Therapy: 135 Patients
- 4 weeks (minimum) of in-person, outpatient therapy sessions
- 2-3 times per week
- Multifaceted standard of care program
- Included stretching, strength training, gait training, and therapeutic equipment
Clinically Proven Results
A peer-reviewed study published in the Journal of Arthroplasty demonstrates superior outcomes with PortableConnect® compared to standard physical therapy

Study Overview
270 Consecutive TKA Patients
135 PortableConnect® vs 135 Standard Therapy
Published: October 14, 2022
Journal of Arthroplasty
Range of Motion at 6 Weeks:
116.7° flexion vs 101.8° (↑15%) | -1.8° vs -3.7° extension (↑51%)
Pain Scores at 12 Weeks:
1.4 vs 2.9 (PortableConnect® vs Standard Therapy)
Conclusion: PortableConnect was superior to standard physical therapy protocol following TKA. Statistically significant differences were found at all time points (2, 6, and 12 weeks) for all outcome measures in favor of PortableConnect®.
Study Results
PortableConnect® demonstrated superior outcomes across all measured parameters
Patients Are More Compliant With PortableConnect®
Total Therapy Sessions Over 12 Weeks
Patients using the PortableConnect system completed an average of 65 more sessions compared to patients participating in physical therapy.
"This frequency and quantity of sessions is believed to be one of the major causes of superior results from the [PortableConnect] protocol. It is nonreplicable, for practical purposes, with standard outpatient therapy."

A Positive Cascade of Effects
The study's authors also noted the clinically established connections between the measured outcomes and further benefits:
Reduced Narcotic Usage
Accelerated Quadriceps Strength
Reduced Joint Swelling & Stiffness
Increased Patient Mobility
Conclusions
✓ PortableConnect® was superior to standard physical therapy protocol following TKA
Statistically significant differences were found at all time points (2, 6, and 12 weeks) for all outcome measures in favor of PortableConnect®.
