Knee replacements and Arthrofibrosis

BluebellJoan

Good afternoon, this is my first post and I'd like to let people in the UK with stiff knees know there there is hope. This is my personal experience with the STAK Tool from STAK Orthopaedics Ltd.

After surviving metastatic breast cancer in 2010 and undergoing a hip replacement, my left knee began to deteriorate, eventually leading to a total knee replacement in December 2020. Unfortunately, due to COVID, I had no in-person physio or prehab, and over time, my knee became increasingly stiff and painful.

Despite physio, my range of motion dropped to 90 degrees and no one could explain why. Finally, in 2025, a private physiotherapist diagnosed me with arthrofibrosis. I found the STAK device online and hired it for 8 weeks—and it’s been a game changer.

After just one session with [name removed by moderator] my knee felt freer and walking became easier. By week seven, I reached 102 degrees of bend - my best result in over 4 years. I'm now able to walk up and down stairs properly again, something I haven't done since before my hip replacement in 2010.

STAK has given me hope and real progress where other treatments failed. The sessions are intense, but with the right support and pain relief, they’re manageable and truly effective. I finally feel like I’m getting my life back.

I'm glad to see that you have found something that works for you. However, we are all different and this may not work for everyone.
