This study aims to evaluate a new home medical stretching device called the Self Treatment Assisted
Knee (STAK) tool to treat knee arthrofibrosis.
Methods
35 patients post-major knee surgery with arthrofibrosis and mean range of movement (ROM) of 68°
were recruited. Both the STAK intervention and control group received standard physio- therapy for
eight weeks, with the intervention group additionally using the STAK at home. The Western Ontario
and McMaster Universities Osteoarthritis Index (WOMAC) and Oxford Knee Scores (OKS) were
collected at all timepoints. An acceptability and home exercise questionnaire capturing adherence was
recorded after each of the interventions.
Results
Compared to the control group, the STAK intervention group made significant gains in mean ROM
(30° versus 8°, p < 0.0005), WOMAC (19 points versus 3, p < 0.0005), and OKS (8 points versus 3, p
< 0.0005). The improvements in the STAK group were maintained at long-term follow-up. No
patients suffered any complications relating to the STAK, and 96% of patients found the STAK tool
‘perfectly acceptable’.
Conclusion
The STAK tool is effective in increasing ROM and reducing pain and stiffness. Patients find it
acceptable and adherence to treatment was high. This study indicates that the STAK tool would be of
benefit in clinical practice and may offer a new, cost-effective treatment for arthrofibrosis
