Great surgeon with a great team to support her patients. She is quite approachable and listens to your concerns. My knee replacement surgery was a success.Too I had my other knee done by Dr Matsen. Everything went well.
She is an excellent surgeon.

Upon meeting Dr Ko for the first time , we shared a quiet moment observing the view of Seattle on a sunny day . It was informal and relaxed . I felt the same with her staff . The entire experience was nurturing and professional . I reside in Montana but decided to have surgery In Seattle after consulting my primary doctor .

I had tremendous pain after surgery that lasted at least a month. I did the prescribed physical therapy and wasn’t able to achieve required flexibility so I had to have a Manipulation Under Anesthesia.
I am now 16 months after surgery and I continue to have nerve pain down my shin and into my foot. I would recommend going to another doctor!. Not happy at all!

Dr Matsen was an excellent choice for my double knee replacements. She was encouraging and supportive and made the whole process simple. Great results! and her faith in my abilities and willingness to be flexible was very important to me. As a woman it was a pleasure to have a female surgeon who I admire and respect. She is a force in her industry and I wouldn’t hesitate using her again or recommending her to anyone else. Choose her with confidence and OPA

Outstanding experience with Dr Laura Matsen! She was wise in her counsel about knee replacement timing. (It's 'go time') Surgery and post-op were extremely professional - she's got a wonderful team around her. And, while it's a significant surgery, she prepared me well pre and post op to understand and manage the pain well. (Ice machines are key!!) She's super smart - tells the truth - listens well -professional - athletic - funny and kind. What more could I ask for?! Thanks Dr Matsen!! While I hope the other knee doesn't need a replacement, if it did, she'd be my first call!

My husband had his right knee replaced by Doctor Laura Matsen Ko in September of 2025. Such a smooth operation! She is one of the best surgeons in the area. She really listens to her patients and gives instructions in a personal and easy to understand way. We highly recommend Dr. Matsen Ko if you are having a knee replaced.
