There is a known link between elevated body mass index (BMI) and symptomatic knee osteoarthritis (OA). While patients who have undergone gastric bypass surgery (GBS) — a procedure that closes off much of the stomach and causes food to bypass a portion of the small intestine─typically lose weight, the comparative impact of this weight loss on knee pain and function has not been measured.
The new study, “The Impact of Gastric Bypass Surgery Compared to Total Knee Arthroplasty on Knee Symptoms,” presented today at the 2014 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), included two groups of patients: 20 GBS patients (16 women and four men) with a mean age of 52 years and a mean pre-operative BMI of 45.6 kg/m², and 40 patients who underwent total knee replacement (TKR) for symptomatic OA.
The groups were matched two-to-one by age, gender and BMI. In both groups, knee symptoms were assessed preoperatively, as well as at six months and one year following surgery. Bariatric surgery patients reported significant improvement in mean knee pain (6.95 versus 2.30 points) and physical function (21.5 versus 7.05) at one-year follow up. When compared to patients who underwent TKR, the percentage improvement in mean pain scores was similar between the two groups at six months (49.9 percent versus 58.3 percent) and one year (62.7 percent versus 68.2 percent). The GBS group experienced a significantly greater percentage improvement in physical function at six months (66.3 percent versus 46.7 percent), and a similar, though marginally non-significant difference at one year (68.4 percent versus 51.5 percent).
Comparatively, GBS patients with self-reported OA had greater knee pain and worse function preoperatively when compared to those without OA, as well as a smaller percentage improvement in pain (63.5 versus 74 percent) and function (66.4 versus 72.9 percent) at final follow up. The study authors recommend that surgeons consider bariatric consultation for obese patients who have knee symptoms but lack advanced osteoarthritis or other conditions amendable to orthopaedic management.

Jawbone UP vs Fitbit Flex — Fight!,
Several asked my opinion of the Flex after I had compared UP to ONE last fall. I’m more pleased with Flex than expected. This review will be specifically for those comparing the Jawbone UP to the Fitbit Flex. For those interested in my review of the One and Jawbone UP it is located here: UP by Jawbone – Large Wristband – Retail Packaging – Onyx:
UPDATE: I uploaded several head-to-head app screenshots.
UPDATE: I’ve found that I am storing quite a bit of water in the Flex band pouch where the module goes. Even though they say it’s shower safe, I’m pretty sure some funky stuff is going to be growing in there in a matter of time… But the band is replaceable!
My journey with personal monitoring devices/pedometers started a LONG time ago: Before Fitbit even existed, with a device called the SportBrain. It was a traditional belt clip style so old that it plugged into a base that used a dial in phone modem to upload the usage data to a server. It was old. But my interest in devices that can help monitor and tell me about my activity started then, and we seem to be now in a golden age of personal data monitoring devices. Fitbit Flex, Jawbone UP, all of the Fitbit clip devices and so many more…
The biggest drawbacks I found on the Jawbone UP were that it had no visual feedback about your daily achievement toward your goal and the fact that it had no visual battery indicator. It wasn’t a problem for me personally, but for those who are hardcore driven on a daily basis to compare and achieve this could be a drawback for you. The next drawback about the Jawbone UP is that it does not wirelessly sync. You have to plug it into the headset jack of your phone to sync. If you are someone who wants data and feedback all day long, this would be a drawback.
The Fitbit Flex does have visual feedback in the form of small white lights: They blink as you’re charging, they have a special blink if you put it into sleep mode and provide 95% more feedback than Jawbone up. Jawbone UP does have status lights in it and they are used, but they could do a lot more with the lights they already have if they chose to.
If you can throw a snap bracelet on, you can easily put on the UP. I did find myself fumbling a bit with the clip mechanism of the Flex like I do when I have to button my own shirt cuffs. After it was clipped though, it feels secure and I am not one to put on and remove devices like this. I want to set it and forget it.
Fit & Feel
The Fitbit Flex feels very comfortable on the wrist. The pictures don’t do it justice. For me personally this is the one defining factor that really makes the Flex shine for me compared to the Jawbone UP. It feels super light weight, doesn’t grab, and doesn’t look nearly as big/thick as the pictures make it look.
The fitbit flex uses tension to stay on, while the Flex uses a clasp. The UP may have a better sense of solid attachment that wouldn’t come off no matter how hard you fling your arm, but the inverse of that is the Flex: It doesn’t have to monkey-grip your arm to be there and stay. You can have it fit a bit more loosely than UP and be comfortable.
When typing on at a keyboard, I prefer the feel of the Flex. The rubber is flat and thin so it adds very little against the edge of a keyboard. The UP doesn’t have the big square bump on the top, but it does have a bracelet shape/size all the way around, so it can prove a bit more of an annoyance up against a keyboard.
The Flex does have replaceable bracelets and colors, which means the device is more convertible and flexible going forward. That being said, it is less visually appealing to me compared to the UP. The UP can be a part of jewelry and most people would never notice. The Flex does have a strange-ish future nerd look to it. I don’t mind that, but some may.
I wear both in the shower with no issues. I’ve done a lot of swimming pool roughhousing with the UP with no issues, but haven’t tried with the FLEX. A commenter tells me that it is swimming approved, though the data provided might not be that useful.
Battery Life & Charging
Both the Flex and the UP charge in very similar almost identical USB adapters. They’re meant to be charged on a computer and in my experience shouldn’t be charged off of a phone USB wall charger. They both charged in similar amounts of time, and the Flex did last about 4 days on a charge. The UP can last as much as 10 days on a new battery, but I found that it has declined some since November. On this case, I say that both do about what they suggest. The UP fits snugly in the charger, while the Flex doesn’t feel nearly as secure…

Well, if the the Flex WINS the ‘Fight’ over the Up, you’d better read this…,
The Flex is pretty good – IF you understand its limitations. And it has a lot of them. This is a 1.0 version, the first wrist-based tracker Fitbit has produced. Since the positive reviewer claims the Flex clearly wins its ‘fight’ over the Jawbone Up, I strongly suggest you wait for the technology to be refined by Fitbit (and others) before spending $100 or more on this.
I also suggest that you tune out the 5-star “this is AWESOME!” reviewers. I’ve had the Flex for 6 months now (acquired at CES 2013, long before retail availability) and initially I too was impressed by the technology. However, with long-term use, I think its inaccuracies make it nothing more than a pedometer with sleep analysis added in (and the usefulness of the latter is dubious as well). The IDEA of it all is excellent: to track your activities and see your progress over time via the great software that Fitbit has developed. However, all of this is predicated on the device accurately tracking your movements. If it fails in that aspect – and unfortunately it does, to a moderate degree – then all of the data and impressive charts and graphs are rather useless. The “awesome!” reviewers don’t realize this (yet) and just assume what they’re seeing is real; it isn’t.
The underlying technological problem, as I see it, is in the placement of the tracker. Up until now, Fitbit trackers were to be placed on the torso. Now, it must be placed on the wrist (yes, the tracker itself can be taken out of the wristband and put into your pocket but all of Fitbit’s calibrations and algorithms are designed for that wrist placement and you are making the problem worse by not having it on your wrist). So, if your wrist movement is ANYTHING other than the usual movement of either running or walking, your step count/mileage is going to be off – often way, way off.
Fitbit markets the Flex as an “activity monitor”, implying that it is capable of keeping stats on your physical activities. Well, because of the wrist location issue and the basic design structure of using two stride lengths for all calculations (your walking and running stride lengths), pretty much any activity that is NOT walking or running cannot be accurately monitored: the accelerometer senses whether you are walking or running and multiplies the appropriate stride length by the number of steps sensed (and arrives at a mileage distance). Any activity outside of that limited ability of the Flex, your stats are innacurate. This includes stair-climbing, hiking, tennis, golf, biking, working out, and pretty much every other “activity” that is not walking or running. The Flex is not really an “activity monitor”; it’s an expensive pedometer (albeit one with “sleep analysis”, which is actually only a record of how much wrist movement you had during the night: i.e., 2 hours of no movement = deep sleep, an hour of sporadic movement = restless sleep).
There are, however, aspects of the Flex that are quite good: it does accurately keep track of your walking and running, it does keep track of your sleeping patterns, and it also wakes you with a silent vibration on your wrist at the time you set to get up in the morning. And once out of bed and into the shower, there’s no need to take the Flex off: it’s almost completely waterproof (pressurized water being the exception). But the best, perhaps life-enhancing aspect of the Flex is its ability to keep you focused on your exercise goals (which is the main reason why, overall, I like the device and its software – to a point): if you DO consider it only a pedometer with cool software, which is what I consider it to be, you will not be disappointed (though the price may not seem worth it to others).
First, there’s the ‘onboard’ function to keep you aware of your progress towards your daily goals (total distance traveled, number of steps taken, or calories burned): each light on the row of 5 small LED lights on the band represents 20% of your goal and a quick glance and a tap on the band will tell you how you’re doing. Secondly, for the actual stats of your progress (or reviewing your daily, weekly or longer stats), you can view them in real time on your phone via the Fitbit App for iPhone and Android, or on your tablet or PC/Mac with the Fitbit ‘Dashboard’. This is where you set your daily and longer-term goals, view not only your stats but see them represented in charts and graphs, and log other information such as weight, weight changes, and food consumed. You can go further, but personally I would feel a bit silly setting goals where I would receive ‘badges’ for reaching them. But that’s just me. Overall though, the software is very good and keeps you aware – along with the band’s LEDs – of whether or not you are staying on track of exercise goals. But, again, just keep in mind that the wrist placement of the device gives the Flex an inherent flaw as to the accuracy of all this data – UNLESS you are using it…
