“I was convinced my knee was stuck. The ‘tight band’ feeling had me thinking something was wrong. Seeing that I’d gone from 78° to 94° in three weeks told me the exercises were actually working.”
Margaret
11 weeks post-TKA
“My PT only measures me once a week. Between visits, I had no idea if I was on track or falling behind. This gave me a number I could hold onto.”
Robert
8 weeks post-TKA
“I kept comparing myself to people on Reddit who were walking a mile at week two. Tracking my own angle helped me stop worrying about everyone else’s recovery.”
Linda
6 weeks post-TKA
“I almost didn’t believe the phone could do it. But the angle matched what my therapist got within a couple degrees. Now I check every few days.”
David
14 weeks post-TKA
“Some mornings my knee feels like concrete. But the chart shows I’m still trending up. That’s what keeps me doing my exercises.”
Patricia
9 weeks post-TKA
“I was dreading getting ‘cranked’ at PT because I thought I wasn’t making progress. Showed my therapist my chart and she said I was right where I should be.”
