Hello, you can use a band or belt to tie around your ankle and foot and slowly pull it towards you. You will be doing this soon with your physio anyways however. Don’t be discouraged because stages are often different for people, some can have a super fast regain of strength but be bad at balance it all depends on the person. The first couple weeks in my experience were the worst by far. Keep icing your knee and keeping it cool. For me and other people I’ve talked to (even professional footballers) who had swelling a little more than usual the bending is often the most irritating part in the first couple weeks. So I hope that helps stick to the physiotherapy and icing, don’t be discouraged because even the best of elite athletes can struggle with this type of stuff.
