A friend had a hip replacement and used Church Hills, normally used for Body Boarding. Said the short blades were great requiring little force with good propulsion. Bonus is there not to expensive.

I sold a pair of Scubapro Twin Jets to a young woman with 2 hip replacements. She did very
well with them. They were the black ones not the colored ones.
I've got an old groin muscle tear that no longer heals, and a hip (same side) with essentially no cartilage left. When I bought my first pair of fins (Tri-Ex blades) I quickly found that they hurt in the pool, so went back to the LDS and exchanged them for a pair of Oceanic Vortex V-12s (splits). Problem solved. Nowadays I normally use a pair of Apollo Bio-Fins (black rubber), because the blade is shorter than the V-12s (IIRR they're different sizes so that isn't necessarily a head-to-head comparison), they are easier to maneuver in kelp without getting tangled, and I prefer the open toe. They're great when I'm doing long shore dives (ca. 3/4 - 1 mile), if probably slightly slower than the V-12s (see caveat above). You can do a frog kick with either, but it won't be as efficient as a paddle fin.
I also have two pair of Scubapro Jet Fins, one size L and one XL. The Ls only work for me with a 3mm or thinner boot, but don't seem to give me any problems, as the paddle blade is a reasonable size. I use the XLs for boat diving in my drysuit, when I won't be swimming very far but want maximum maneuverability and kick flexibility, but they definitely strain my groin muscle as well as tend to give me cramps if I have to swim any significant distance in them, because the blades are huge and very stiff. Definitely, you want to frog kick in these things whenever you can, but I can't for any length of time without pain.
I once tried a pair of Manta Rays while testing a new drysuit, but unfortunately they screwed up my trim so much, being so much lighter than the natural rubber fins I normally use, that I spent the whole dive 45 degrees head down and can't make any useful comparisons. Haven't tried the Force Fins. We have one local guy who's leg was a mass of pins etc. following an accident, who was using the Slingshots. Indeed, he was a finalist in the contest to win a free trip because they allowed him to rehabilitate so well. Don't know if he won the trip or not. But see this review here:
My tests of 3 recent ScubaPro and AquaLung fins
Bottom line, lots of us like Bio-Fins, and they always seem to test at or near the top of every category no matter who does the testing. Other fins tend to vary a lot more based on personal preference. I know on the surface, when my trim was irrelevant, I seemed to be doing an awful lot of work for very little result with the Manta-Rays compared to my Bio-fins, and the Scuba Lab tests I've seen were pretty mediocre. But some people love them.
HTH,

the thing with scubalabs tests is that they rated the deep outdoors 6-gill fins as a testers choice and the aps mantarays as a midlevel performer- they are essentially the same fin!
i owned a pair of white aps mantarays which i just sold to get the bigger size. when i used them they really felt like a i was wearing no fins at all. they did provide a little less power than my full size tusa liberator x(cramp machine). however it was very easy to kick more with the mantarays for added power so this kinda offset that.
i heard though that the black model is a bit stiffer and could provide a little more power.
I imagine the difference in test ratings is due to the fact that other fins have improved in the meantime, and/or different/improved test protocols. Here's the most recent test they listed under fins, (which also has the Bio-Fin Pro):
