Part 2 – Healthy Living for Life – Learn About Hip and Knee Replacements

welcome back we're continuing our conversation with Dr Kerry Hale about knee replacements so thanks for sticking around with us Dr

Hale so just to continue that conversation like we said our knee surgeries regardless of whether it's the full replacement or our partial replacement are they always 100% successful with patients they're not always 100% successful knee replacement surgery is a very successful surgery and somewhere you know 90% to 95% of patients are really happy that they had it done but there's always complications that could go along with a big surgery like that okay are there things that patients can do to ensure that success rate and that the best thing to do again is to try to be as as fit and healthy as you can be going into it and then certainly physical therapy and doing the the exercises that we need you to do after surgery plays a really big role in getting the knee range of motion back and the strengthening in the leg back after surgery okay and then how long does that new knee usually last for a person so we don't entirely know the answer to that there's really good 15 year data out of the Mayo Clinic showing that at 15 years 98% of all knee replacements are still functioning well and the interesting part of that data is that it's data from implants that were you know 15 20 25 years ago so hopefully the implants that we are using now the surgery that we're doing now will be even better lasts longer okay has there been times then where that 15 years has come up and somebody has been a good candidate for a second knee replacement or does that not really happen that definitely does happen for a number of different reasons and that's called a revision knee surgery and those are successful as well although the the success rate goes down a little bit and the complication rate does rise a little bit with a second third fourth surgery okay and we were chatting during the break and you mentioned that knee replacement surgeries are actually on the rise can you talk about that a little bit yeah they've definitely skyrocketed in the US and worldwide and the number of people that are living longer and are more active as they're getting older as has risen dramatically and so therefore the need for any replacements has as well okay and as health insurance usually you pay for any replacement surgery yes they do sometimes there's different conservative treatments medications physical therapy that kind of thing that needs to be done first before the insurance approves replacement surgery but if you go through that then okay great so let's switch gears or joints as the case may be and talk about hip replacements now what are some of the reasons why somebody might need a hip replacement surgery very similar to the knee replacement the most common cause is that osteoarthritis wear and tear arthritis of the hip sometimes injuries can play a role when we are younger there's an entity called avascular necrosis or austria necrosis of the hip that can occur which is the same outcome needing to have a hip replacement just a bit of a different mechanism of an injury to the hip so again as we asked about knee replacement are there other alternatives or options for folks other than surgery that I know the hip obviously is a little bit different than the knee but can you do physical therapy and things like that for that instead you can do physical therapy anti-inflammatories I typically don't recommend much in the way of injections for the hip they don't seem to work nearly as well as they do in the knee so okay and then are there partial hip replacements is that similar to or are there different kinds of hip replacement surgeries there's a what we call a total hip arthroplasty which is what the vast majority of surgeons in the us are doing there's something called a hip resurfacing surgery which has for the most part fallen out of favor because of the the bearing surfaces they're used in that surgery it's called a metal-on-metal hip and most of us are not doing metal on metal hips at this point because of some issues that have arisen with them okay so what is used if it's not metal anymore that yeah so in a hip replacement surgery the the femoral head or the ball of the hip we take that out and a stem typically a titanium alloy stem is used to it gets inserted in the upper portion of the femur and the bone grows on to the stem and then either a metal or ceramic head fits on to that stem and then there's a again a titanium cup which gets inserted into the pelvis into the cup of the hip and again bone grows onto the back of that and then usually there's a plastic liner that snaps into the cup and so the head articulates with the plastic liner okay Wow yeah so metal still is at play it's just avoiding that metal on metal part that is correct okay gotcha okay and so again at what point would you recommend hip replacement surgery for somebody who's experiencing pain or different hip conditions yeah so it's it once again it's when that pain and dysfunction is bothering people enough in their daily life hip replacements may last longer and there's actually a little bit of a better patient satisfaction rate overall with hip replacements versus knee replacements so patients that are a little bit younger at times with hip arthritis are offered hip replacement surgery maybe versus a knee replacement surgery okay all right it's a great information we do need to pause for yet another break but there's still more to learn about hip replacement surgery we'll continue our discussion with dr Hale right after these messages stay with us we'll be right back
