What could be causing your knee pain?

Cartilage & joint

Cartilage & joint

Joint surface changes may contribute to stiffness, swelling and pain with load.

Meniscus

Meniscus

Tears or degeneration may produce catching, locking or joint-line pain.

Tendons & ligaments

Tendons & ligaments

Irritated or overloaded soft tissue may contribute to pain, weakness or instability.

Movement & mechanics

Movement & mechanics

Strength, mobility and movement patterns may influence how the knee is loaded.

Different problems can produce similar symptoms, which is why identifying what may be contributing to your pain is so important.

Our approach

Our goal is to support the body's natural recovery processes while improving strength, movement and function through an individualized evaluation and care plan.

How long does it take?

Every patient responds differently. The timeline below reflects general patterns some of our knee patients have reported and is provided for educational purposes only—not as a prediction of individual results.

  1. 1

    First 3–7 days

    Take it easy. Some soreness at the injection site is normal and is a sign the healing response has started. Most patients return to daily activity right away, with no formal downtime.

  2. 2

    Weeks 2–6

    Early changes show up first as small things — less catching or locking, quieter joint mechanics, easier stairs, better sleep. Gentle strengthening and mobility work begin.

  3. 3

    Weeks 6–12

    Tissue remodeling continues and most patients notice a clearer drop in day-to-day pain along with improving strength and confidence in the knee.

  4. 4

    3–6+ months

    The healing response continues well past the procedure. This is typically when patients return to the activities that mattered most — walking distances, hiking, dancing, or training.

Karen

Knee pain patient

I turned 60. I can say that my knees feel like I'm 27 — and that's what I want to stress more than anything else. I feel fabulous, and no pain.

Karen could barely walk and had severe night cramps from knee degeneration. After cortisone shots failed, she had a regenerative joint procedure in December 2023. A year later she is walking and dancing again with no pain.

60. Um, I could say that my knees feel like I'm 27 and that's what I want to stress more than anything else. I feel fabulous and no pain.

Hello, I'm Dr. Brian Petri from Regenerative Medicine of Ringham and I'm here today with Karen who is a patient of mine who came in there about a year over a year ago and you were complaining of some pretty significant knee issues at that time. Can uh you just kind of refresh uh us and let us know what you were actually experiencing back then?

Well, I could barely walk and it was very hard for me to walk and I was getting cramps in bed and couldn't get up. Couldn't go to the bathroom cuz the cramps were so bad and um so I needed help. I saw other knee doctors but no one was helping me.

What was your diagnosis at the time? What did they tell you?

Degeneration in my knees.

Degeneration. Did they recommend surgery for you?

Cortisone shots.

I had one cortisone shot on my right knee and I felt that pain from the shot for a whole year and it wasn't the pain of the knee, it was the pain from the shot.

So, I wasn't happy and I didn't want to go to that procedure again.

So, I came to you and when I read about you and saw you on Facebook and I just knew that you were the right person and so I came. So when you came in, we evaluated you and we determined that you were candidate for the procedures we do here with regenerative medicine for joint rejuvenation. And we did that procedure. It was I believe December 2023.

Yes. The the results was so worth it.

Tell me about the results you have and this is a year later. So what what have you been able to do over the past year?

I rested up for a couple days after the shots and I just took it easy. I I slowly did rehab on myself at home. I didn't do anything vigorous

and um slowly got my strength more and more and no pain. Just the best part is no pain to walk and dance.

That was the one thing you wanted to be able to continue to do is dance. Correct. And have you been able to?

I've been able to dance and I've been able to walk and feel like myself and I turned 60. Um, I can say that my knees feel like I'm 27. And that's what I want to stress more than anything else. I feel fabulous in no pain.

Okay. Thank you, Karen. Thanks for sharing that story. That was awesome. Thank you.

Kathy

Knee pain patient

I got the injection about nine weeks ago and since then I've had no pain — my knee hasn't locked up at all since.

Kathy had five years of daily knee locking and 10-out-of-10 pain after a failed meniscus surgery, and was told she needed a total knee replacement. Nine weeks after a regenerative injection she reports almost 100% improvement and can walk the beach pain-free.

Read the full transcript

coming to your office for one reason, the last 5 years or so. I've been dealing with um my knee a lot of pain and locking up every day. So, I saw your um article on Facebook about regenerative medicine and I came in and talked to you, went to one of your seminars. Um thought it was something I'd rather try instead of having surgery. Um, I got the injection about nine weeks ago and since then I've had no pain or my knee hasn't locked up at all since and it's great. It's it's amazing.

Okay. So, you had prior to several years ago, you had surgery to the right knee.

Correct. I had a tear and um the surgeon um said that I should get rid of the locking um but it didn't. It was good for like a few days after the surgery and then it was the same thing it was before I had the surgery. So, you continue to experience pain in the knee,

correct?

And at some point, you went for a follow-up MRI was a few years later.

Um, you sent me for MRI and that's when I discovered that I had a a degenerative um meniscus and so you said to try maybe the stem cell that that might help to repair it instead of surgery because I really didn't want to have surgery again since it didn't work the first time.

Yes. your doctor had recommended that you undergo a total knee replacement,

but I really didn't want to have surgery because it would be a long recovery period and I'd rather try something all natural than to have surgery again. So,

and what kind of pain were you having with that knee?

Um, it was severe. It was I mean on a scale of 1 to 10, it was like a 10, especially when it would lock up, which was every day. So,

um, and when it locked up, I couldn't walk on it or anything. So, um, it was really painful. That's why I was glad I saw your your thing about regenerative medicine and gave you a call and decided to come in and talk about it. So,

how long after we did the procedure did you start to notice uh some changes within that knee?

Um, immediately actually. Um, there was no locking. Um, there was a little bit of pain after having the injection obviously, but within a few days that was gone and um, I took it easy for the first few weeks anyways. to stayed off of a lot. But I mean, there was no pain, no locking. Like within the next day, there was no, you know, locking. It was just pain from the injection. So,

okay. How much improvement would you say you've had overall?

I almost 100%.

100%.

It's amazing. I can I don't have to worry about it locking up anymore and I can go for walks and and do things without, you know, being in pain.

On the beach again with your husband, which was something that you weren't able to do before. And well, I mean, yeah, I could do it. It would be painful, you know, it would hurt, but I enjoy doing it. So, now I I have done it just once recently, and it was great being able to walk without any pain.

That's awesome.

It's It's great.

Is this something you'd recommend for other people with

Definitely. If you don't want to have surgery and you'd rather go an allnatural way, I would definitely recommend this 100%. So,

okay.

It was amazing.

Glad I did it.

Okay. Thank you, Kathy. That's the real

John

Knee pain patient

I've lived most of my adult life with just an ache… The last two weeks it's not there. The flexion is smoother. There's no snap and crackle and popping — nothing.

John, a triathlete facing a knee replacement, had multiple diagnoses in one knee including osteoarthritis, a lateral meniscus tear and patellar tracking problems. Early in the recovery process, his daily ache and joint noise are gone and he is hopeful about running again.

Read the full transcript

I have been heading for a knee replacement and I'm still an active athlete and I'm still way too young to get a knee replacement. So, I looked into options and in looking at um a bunch of different providers who um had the offering that I needed, Rain Regen was the place. If you can have it wrong with the knee, I have it. I have ag disease. I have a slightly displaced patellar tendon. I have osteoarthritis trimpartmental. I have degenerative arthritis on the end of my femur with my um articular cartilage. I have a patellar tracking syndrome problem. I have a torn meniscus lateral side. So, there's a lot going on in there. And it got to the point where um I couldn't even get it scoped or get the meniscus fixed. Uh insurance said they would not let anybody go do anything if it wasn't to replace the knee. It's been amazing so far. The first few weeks, honestly, I didn't feel much. I didn't expect to though obviously you know with everything I was told I knew how the process worked. Um but I've lived most of my adult life with just an ache. Like my knee would just ache every day to the point where I didn't even think about it. Never never a thought because it was just every day. The last two weeks it's not there. It was enough to make me notice it because I'm so used to it being there that I'm I'm noticing that there's no ache in my knee. Like I'm expect like I wake up in the morning I'm just like there's my knee and it's not there. There's no that ache isn't there. The flexion is smoother. My knee used to make a lot of snap, crackles, and pops when I would squat or do lunges or and it's quiet. There's no noise. There's no snap and crackle and popping, nothing. Well, we're early in the process, so I'm still rehabbing everything, but mentally for me to be able to squat down and not hear my knee crackling all over the place is huge for me. Um, it gives me hope that six months from now, eight months from now, I can get back to running because I was pretty much told my running career was over. And as a triathlete, it's a big part of the game for me. Um, so, um, this gives me a lot of hope that that by the time this process kind of rolls itself out, I can get back to racing.

David R.

It went from maybe an eight in the pain level to maybe a four. I'm able to sleep at night… and I'm happy with not having to replace my knees.

David was scheduled for a knee replacement on one side and had prior meniscus surgery on the other. Two years after his procedure, his pain dropped from an 8 to a 4, he sleeps through the night, takes no medication, and avoided replacement surgery.

Gail

Knee pain patient

I have even had days in the last week or two where I forget that I had a knee problem… Overall, I would say 90%.

Gail, an avid martial artist with knee osteoarthritis, was approaching a knee replacement after cortisone shots, gel injections and physical therapy. Following an allograft injection she reports roughly 90% improvement and can climb stairs normally again.

Read the full transcript

My name is Gail. I have a history of knee problems. I had osteoarthritis in the knee and um getting close to a knee replacement and did not want to do that. The pain level was I would say would range between 8 and 11 on a scale of 1 to 10. Um couldn't really go up and down stairs very well. Kind of like toddler style, one step at a time. And I'm a I'm an avid martial artist, so it was kind of interfering with some of that. I have been um seeing an orthopedic, a couple of different ones actually. So I have had uh cortisone shots. I did um gel

shots, um physical therapy, you know, in between there somewhere. You know, some of those things would work for, you know, a week, a month, a couple of months, and then it would just, you know, in some cases almost feel worse, but certainly not any longlasting improvement. One orthopedic recommended a knee replacement. Another one seemed to think, well, you know, is the pain that bad cuz you're walking around.

And then somebody had mentioned our office to you and cuz we were doing alligraph injections which contain growth factors and stem cells. I actually didn't know what you were doing. All I really had was was your name and your phone number.

Okay.

But I figured, you know, why not, right? I was nervous because I had had, you know, cortisone injections and gel injections and they were sometimes painful.

Was it painful in any way?

No, it was like the tiniest little pinch.

Okay.

You know, I stressed myself out more thinking about it than

That's what we hear a lot. And uh when did you start notice some changes?

Um I would say almost immediately. Some small things like um just you know walking it didn't seem to to hurt as much. Um I used to get a lot of clicking you know when I would be exercising or stretching and and the clicking seem to diminish. So that happened pretty quickly. You know 75 to 80% of the pain is gone. Okay. there. I have even had days um in the last week or two where I even forget that I had a knee problem and all of a sudden I'll think,

"Okay,

oh, my knee doesn't hurt.

I am no longer toddler style." Most days I can just walk up and down the stairs like a normal person. Overall, I would say 90%.

90% better. Okay.

And I think it's going to get better,

right? And that's what happens. That's what they do.

I feel like it is. I feel like each time I'm here, it's it's a little bit better. So,

Okay. Great. Is this something you'd recommend?

Absolutely.

Yes, I have. I have given you name out.

Oh, yeah. All right. Well, thank you.

He might not tell you, but I have.

Is there anything else you'd like to share?

Uh, just thank you.

Thank you. You're quite welcome.

Thank you. Thank you.

David B.

Knee pain patient

I had the injections in my knee. I have zero pain in there now.

David had excruciating knee and ankle pain from years of work on ladders and roofs, plus a grade three ankle ligament sprain. One month after an A2M knee procedure and advanced PRP to the ankle, his knee pain is gone and he is planning long hiking trips again.

Read the full transcript

When I get to about here, I'm starting to get a a sharp pain across my knee. And then there's a lot of tightness there, it's always swollen. Uh, and when I get down this low, I feel a lot of pain in my ankle. When I go to stand up, I have to push with my left leg. I can't really push my right leg anymore.

Hello, this is Dr. Brian Petri from Regenerative Medicine of Rainom. And uh I'm back here with David who underwent a regenerative medicine procedure which we uh performed on January 29th. So it's been exactly uh 1 month since we did that procedure.

I had gone to an orthopedic doctor and

they talked about doing surgery uh giving uh injections first and then I had done physical therapy. I came and saw Dr. Petri. We talked about regenerative medicine and I've had surgeries before. I didn't want to have surgery again. Um, my pain from doing work all the time down on my knees, up on ladders, up on roofs was excruciating at times. Uh, you know, probably 7 to 10. Uh, when I calmed down, probably down to a five out of 10. Uh, my ankle was 7 to 10 all the time. Uhhuh. when I got out of bed, it it really hurt. Um, I had the injections in my knee. I have zero pain in there now.

Okay. So, uh, when Dave came in to see me, we, uh, determined that he had significant degree of degeneration in both his knees, but more so in the right knee and on the, uh, the ankle, he had a severe grade three ligament strain on the, uh, outside of the ankle region. So we did a what's called an A2M procedure to stimulate healing respond and the U procedure we did on the lateral ankle was a advanced form of PRP which stands for plateletri plasma which usually when you have severe ligament uh sprains it takes quite a while for it to heal. So it was interesting to see uh the results that you got with just within four weeks for what we did. So So what are you experiencing now Dave and how has it benefited you? Well, in the knee, I have no pain.

There's no pain in the knee. It's completely resolved

right now because I haven't done anything really to uh to exercise it other than stretching it. It feels weak in the muscles around there, but I don't have the pain that I had in the knees before at all. At no time pain in my ankle. Uh, as I said, I I had a hard time getting up in the morning, getting out of bed. But now, you know, in the morning, it's probably 3 to 5. Uh, during the day, once I get loosened up, I have no pain. And then at night, when I sit down again, uh, it swells up a little bit and I have pain at night.

All right. So, it's still your body's still healing. It's only been four weeks and that healing response is still going to take place over the next several several months, actually. Okay. So, you're going to continue to get better and you're going to be starting to do more rehabilitative exercises at this point, which is only going to make it stronger. Now, you did say that your passion was to travel back to Ireland and

to Ireland and throughout Europe and and to hike

to do a lot of hiking over there, right? So, and is that something you were seriously concerned about doing before because you're getting ready to retire, correct?

Right. So last summer I hiked about 13 miles a day um in Norway,

okay,

during the summer and I really suffered and when I came back I did I feel like I did damage to it. Um I didn't think that I could do it again this summer, but right now I'm pretty optimistic about it.

Okay, that's great. And you're going back again. I'm going to hike out through Greece and Albania and over more in Eastern Europe.

Okay. So, you're glad you did these procedures then didn't need to go through the surgery. Okay.

All right. Anything else? Would is this something that you would recommend to anybody else experience the same type of uh

Absolutely. I mean,

you know, the great thing about it and as I said, I've had surgeries before. There's no downtime. I mean,

the downtime was what I did to myself. I I was still cautious. You know, you don't know if it's going to work. And I was cautious. I I was afraid that I'd feel the pain still, but I haven't. And I I don't anticipate that I will.

Okay. So, it's something you would recommend.

I Yeah, I would recommend it.

Okay. All right. Thanks for sharing your story, Dave. Appreciate it.

Thank you. All right.
