After the TKR, did you do PT and for how long/often, and did you do the post-op exercises (usually three times a day) as soon as you got home? Scar tissue usually forms due to inactivity after surgery.

I don't know that removing the scar tissue will help, or rather how much it will help. But check with the surgeon about post-op exercises. I think for all joint replacements, if rehab exercises are ignored or not done fully, scar tissue will form and place limitations on flexion. I'm a little surprised you're at full extension (zero degrees) with the scar tissue.

I'm not assuming, but so often scar tissue forms due to post-op inactivity. A successful joint replacement and recovery are about 10% due to the skill of the surgeon, and about 90% due to the work of the patient pre and post op.

I'm a 68 y/o male and had both knees replaced in 2022. I worked with a trainer before the surgery, did all the post-op exercises with a PT and at home, and am in the gym 6 days a week. I'm very sorry about what's going on with you at such a young age. I get the frustration. Hopefully the scar tissue removal will help, and please ask about a post-op regimen to get your knee flexion back.

All the best to you.
