Knee issue while diving

[alexdives]

Except it didn't.

Maybe. Nothing says that the torn meniscus is causing this issue, could be something completely different

When learning diagnostic skills in medical school I was taught that when you hear hoof beats in the woods you don't think of zebras.

Find your nearest scuba instructor and have him/her write you a prescription for a dive scooter.

Now that's the best idea I have heard yet!

You might try modifying your Mares fins to a scoop fin design. Your avanti quattro fins have a dead spot just beyond the toes, which increases the load on the knee. I've worked on this concept for decades, and the scoop design is more efficient than a straight blade, or even the Quatro design. You need to replace the center of the fin with a flexible interior, which at the toe is straight across, but then goes to a full semicircle design at the end of the fin. This "scoops" the water out the back of the fin, and reduces a lot of the strain on the knee. You can see the difference on the Voit Viking fins I modified in the 1970s. You can see the number of fins I've evaluated over the years (and that photo is not complete). If you need more information, PM me.

Depending how old you are here's a personal perspective.........

I'm 70, 71 in November and still have all my original parts! LOL.

"Back in the day" as in 44 years ago I ran my one marathon (26.2 miles) in 3:27. Never thought I'd beat that so only did 6.2 mile 10KM runs until the last 15 years, now only long brisk walks.

Especially last year my knees would feel "stiff" a bit not extreme pain, etc. I have moderated to first using the full foot and heel strap Scubapro TwinJet split fins and the past few years shorter fins.....

Just came off a week diving Cozumel in my all rubber Oceanways Aquapro full foot fins copies of 60+ year old Cressi Rondine with the Swallow bird logo on them. I love them as they'r easier on my knees and I get around just fine being a swimmer.

The other fin I own is the Scubapro GO Sport for boots. A little stiffer than my all rubber full foot fins but still doable.

I dived them in Raja Ampat currents Nov. 2023, Maldives Feb. 2024 and Bali May 2024. The shorter length is MUCH more maneuverable and while a tad stiffer on my knees still keeping me "in the game" for the foreseeable future.

I'd suggest trying a softer and maybe shorter fin. Also, for OCEAN diving I don't think frog kick would be any easier on your knees In fact I think the torsional motion tends to twist one's knees worse than a moderating flutter kick.

You can slide a bit sideways with minimal flutter kick as in a light kick and glide, etc. and still not stir up the bottom. Yeah, I know the tech / cave / whatever community is always preaching for people to learn to hit reverse all while posing with hands clasped in front of them looking cool.......Whatever.....

I put a single finger down on a rock or whatever, push myself back, inhale a bit and helicopter around before gliding off the next point of my dive and don't kill the bottom dwellers, etc. I always say if you can't feel your fins they're likely below you kicking the bottom up

In an ocean current I regularly leave folks doing frog kicks behind !!! LOL......

Just one old guy's opinion!

Appreciate the perspective.......
So the Chiropractor figured it today. It looks like either a small tear in my patellar tendon or maybe some scar tissue there. He was working on my knee and hit the spot. It was immediately clear he had found the issue. He explained that almost anything with a fin is liable to put pressure on that spot but since it didn't appear to be a major tear, it should heal. Probably will see ortho just to get another viewpoint.

I've heard that split fins reduce the stress on your knees. Something you may want to look into or try.

This has been our experience. Not sure on the physics of it all, but we’ve found it helps.

I had a giant fluid filled cyst form adjacent to my knee and it hurt like hell when I did activities. Had it drained but ultimately had to have it removed in an open surgery. My knee was overproducing synovial fluid from an ACL and meniscus tear and repair.
