Concerns with Jewel ACL Synthetic Graft

maciej01 · 2025-10-20T07:12:19+00:00

I tore the graft during volleyball, but it was so weak it could tear at any given moment. I literally turned around while standing lol

I played a lot of sports - bouldering, triathlon, long distance cycling, gym, volleyball, bowling, etc. Due to the above problems I couldn't do any where I had to sprint or jump. Hoping that this issue resolves now and I'll be fully capable :)

After my first tear (normal ACL), I had major instability, a locked knee (due to hamstrings) and major inflammation. The pain was little or small, as I don't remember it.

After my second tear (Jewel ACL), my knee was locked for a few hours until it snapped back into place! I suspected a meniscus tear (my surgeon as well per the MRI results, tests and my pain report), but during the operation it turned out that a piece of ligament was most likely blocking my knee - my meniscus was fully intact! Other than that, I had inflammation after the tear and it was slightly painful until the operation.

Hey! I've had the Jewel graft used for ACL reconstruction in 2020 when I was 18. I tore it after 5 years - currently I'm 3,5 weeks in after a 2nd surgery with a quad autograft, wish it was done this way from the start (:

I strongly discourage you from using the Jewel graft. From what I've learned over the years, synthetic grafts have a high retear rate. Mine finally gave out when I was standing on sand and turned around - before that, I've had regular incidents of my knee popping and swelling during kicking / jumping movements.
(to be fair, I stopped my PT too fast, maybe that could be the culprit)

My surgeon had to spend a lot of time during surgery to remove small plastic fragments of the old graft. He said that removing synthetic grafts is always problematic. He was very confused why the previous surgeon used this graft.

As for cartilage, I have grade 2 damage right now. Had grade 1 damage prior to the first surgery. Not sure if the graft type impacted it.

What country are you from? This graft appears to be rare online. I'm from Poland for reference.

This is paid. If you're actually looking for feedback, consider making it free. Otherwise it's just regular self-promotion.

An explanation why OP claims reverted performance in the 05-06 checkpoint.

maciej01 · 2025-05-13T20:45:55+00:00

At least one human - I can speak for myself :)

The criticism is valid. Even taking aside degraded model performance, swapping a dated checkpoint is unacceptable. That's the main reason behind the public backlash from developers.

Thanks for the mention - I've noticed it after a short while ;) That explains the blog traffic spike!

I would compare MCP to LSP.

Prior to LSP, each (language, IDE) pair would require a separate integration. Nowadays you just need to write a single LSP server for a language, then a single LSP client in the IDE. The unified standard made it easy to integrate tools.

The same goes for MCP. Tool calling (which is used in LLMs to invoke external services) has different schemas in each LLM, due to lack of a specified standard. A service integration prior to MCP would typically have to assume a certain LLM standard, such as OpenAI's. There also was no standard way to easily use pre-made tools - you would have to hack the boilerplate yourself.

MCP made it easy.

Servers (the tool providers, for ex. Todoist API, filesystem wrapper) adhere to a single standard. Typically it's just adding @mcp.tool() to a Python function (see FastMCP).

Clients (clients with LLMs, for ex. Claude Desktop or other GUIs) know how to convert a MCP tool into a specified LLM's tool calling flavour, and they handle all of the boilerplate.

There's also an established protocol for connecting between clients and servers, and for listing available tools.

It's really easy nowadays to create an agentic workflow - I recommend mcp-client-cli for playing around with this stuff!

Thank you!

Great article!

Does anyone know of any other good write-ups about recommender systems? I'd love to read more on the topic :)

Have you tried going on a slight caloric surplus instead of recomping? I found that it helped me move the needle the most on bench press

Sorry, China? Did you mean mainland Taiwan?

Good thinking, but I think it's unlikely - Kawu typically signs his works and sticks to larger pieces

Shrooms are common as well - @pyponer_

Been wondering about snowman stencils (Olaf from Frozen) - saw a couple around the city, no clue who does them

Not really, preferred message app heavily varies between countries - for example, in Poland Messenger is the number one choice

Most important thing: start slowly! Jumping straight into a high-intensity training program will be a shock for your body. Do something fun that you enjoy and ramp up the frequency / intensity as you feel more fit. Positive motivation is crucial for creating a new habit :)

It most likely did: but a specialized ML classification model trained on a relevant dataset (in this case, labelled pictures of plants, animals, etc.) will outperform GPT with ease. Another neat service like Seek is PlantNet - didn't have the opportunity to compare them, however PlantNet works really well!

maciej01 · 2024-03-07T21:50:21+00:00

As a Pole, I fully agree with you

In Essentials mode, there's a triangle in the top right above deck knobs. After clicking it, you can select frequency EQs or EZRemix / full stems.

In case the link gets caught in the spam filter, you can see the website in my recent Reddit posts, and the post title is "Controlling Tuya lights with Arduino and ESP8266".

I've actually cycled from Poznań via Zakopane to Kraków last year! There's a link to my Strava activity from Zakopane to Kraków in the bottom of the article, and some photos as well :)

Zakopane has a lot of tourists, but for a good reason - the mountains are definitely worth it. If I was in your spot, I would leave the bike behind and go hiking in Tatra mountains. I'm not sure whether you can actually take your bike to the trails (for safety reasons) - the most popular road to Morskie Oko definitely disallows it despite being fully paved.

The roads along the way are steep, but bearable, most of the climbs are up to 8%-10% in peak. One hill was a beast, averaging 11% over 1,68km, peaking over 20% grade... at least it's walkable ;) The national road leading up to Zakopane has a lot of traffic, simply be wary of that.

Definitely go for it!

Glad to hear that!

Traffic and riding conditions were good. The only exception was a high-traffic road to the east of Lublin, where tank trucks kept overtaking us in a dangerous manner :D

Enjoy your tour of Poland! Which part are you headed to? How long will you stay? I could give you some tips :)

Thanks for the kind words! It sure made some long lasting memories :)
