It's only a month since you had this surgery and it's normal for extension to take longer to achieve than flexion, but it will come, given time. Certainly, it's too early to be worrying about it. Slow and steady progress is what you want with extension.Extension - let's have a discussion. I'm not there, it feels like I'll never get there. I just can't get my leg straight, for long. Of course its still swollen, and I take that into consideration, but I'm a little concerned about it. Once I do get my leg relaxed enough for good extension, it doesn't last long at all. Its like my hamstring & IT bands are making fun of me!! Any tips to help me out?
