Design outcomes

Primary

MeasureTime frame
Improvement in health status based on the KOOS (knee injury and osteoarthritis outcome score). The primary outcome will be collected: at enrollment, after 3 Weeks, 1 day pre surgery, 2 weeks post surgery, 6 weeks post surgery, 10 weeks post surgery, 14 weeks post surgery

Secondary

MeasureTime frame
Kinesiophobia (TAMPA scale) subjective pain level (numeric VAS), subjective function (numeric VAS), subjective patient satisfaction (numeric VAS) Physical therapy/ lymphatic drainage needed (yes/no), ability to work (yes/no) patient-relevant structural and procedural improvements (pSVV) Exploratory medical endpoints: Thigh circumference, and lower leg circumference and patellar center. Angular measurements (range of motion) Stability test (anteroposterior stability of the knee joint). End of study only: Coordination, quick strength, and agility Exploratory endpoints on app use (intervention group only) via custom-developed questions.
