Preventing Falls and Fractures After 50: Weak Knees, Thin Bones

A broken bone after 50 is usually two problems meeting: bone that has quietly thinned, and a fall you did not see coming. You can work on both, and the fall half responds faster than most women expect, mostly to balance and strength training rather than to caution.

I spent a year being careful. Careful is not a plan. Careful meant I stopped walking on the gravel path, took the stairs one at a time with both hands on the rail, and turned down anything that involved a ladder, and at the end of that year my legs were weaker than when I started and I felt less steady, not more. The women I know who have genuinely reduced their risk did something almost opposite: they trained the thing they were afraid of losing.

Why falls and bone loss belong in the same conversation

Osteoporosis does not break bones on its own. It sets the stage, and a fall provides the force. That is why fracture risk after 50 is really two risks stacked on top of each other, and why working on only one of them leaves half the job undone. Roughly 1 in 3 women over 50 will have an osteoporotic fracture in her lifetime, and the classic sites (hip, spine, wrist) are exactly the ones a fall onto a hard floor tends to load ¹.

Falls themselves are not rare or exotic. The World Health Organization counts falls among the leading causes of injury worldwide, with adults over 60 carrying the greatest burden of serious harm ². Most of those falls happen in ordinary places doing ordinary things: a rug edge, a dark landing, a wet step, standing up too fast from a low chair.

The knee problem nobody frames as a fall problem

Here is the part specific to women reading this site. An arthritic knee is a fall risk factor in its own right, and it rarely gets described that way. Knee osteoarthritis brings pain, weak quadriceps, stiffness, and in many women an occasional sense of the knee buckling, and every one of those changes the way you walk. You shorten your stride, you spend longer with both feet down, you look at your knee instead of the floor ahead, and when your toe does catch, the leg that has to shoot out and save you is the leg that is weak and sore.

That is the good news hiding in the bad news. Strengthening the quadriceps and hips is already the core of non-surgical care for knee osteoarthritis ³, and it is also part of what keeps you upright. One block of work, two problems. Our guide to staying active with arthritic knees covers how to load a sore knee sensibly, which is the bit most women get wrong by doing too little.

What the evidence actually supports: balance training, not caution

If you take one thing from this article, take this. Exercise is the fall-prevention step with real trial evidence behind it, and the exercise that works is not gentle stretching. Cochrane’s review of exercise for preventing falls in older people living in the community found that exercise programmes reduce the rate of falls, with the strongest effects from training that challenges balance and includes functional movements, and often a strength component alongside it ⁴.

What that looks like in practice: standing on one leg while you brush your teeth, heel-to-toe walking along the kitchen counter, sit-to-stand repetitions from a dining chair without using your arms, stepping over and around obstacles, and progressing the difficulty as it gets easy. Tai chi and structured strength and balance classes both fit the description. The catch is dose and persistence. The programmes that show benefit involve several sessions a week, progress over time, and keep going, because balance is a skill that decays like any other when you stop practising it.

The same training is doing double duty on the bone side. Weight-bearing and resistance exercise helps preserve bone density in postmenopausal women and reduces falls, which is why it appears in bone-health guidance as well as fall guidance ⁵. If you want the bone-density background, our article on osteoporosis and bone health after 50 covers the scans and scores.

The boring half: house, shoes, eyes, medicines

None of the following is interesting, and all of it is cheap.

The house. Lighting on stairs and landings, a lamp within reach of the bed, both stair rails secure, loose rugs taken up or taped down, cords out of walkways, a non-slip mat in the bathroom, and the things you use daily moved to shelves you can reach without a stool. Do the walk-through with someone else, because you stopped seeing your own hazards years ago.

Shoes. Indoors counts. Slippers with no back and no grip are a genuine hazard, and so is going about in socks on wood floors. What you want is a shoe that stays on, has a low heel and a sole with grip, and fastens.

Eyes. Get vision checked on schedule, and be aware that new varifocals change how you judge stair edges. Many people take a few weeks to adapt, and stairs are where that adaptation shows up.

Medicines. Sedatives, sleeping tablets, some antidepressants, and blood pressure medicines that leave you light-headed when you stand are the usual suspects, and risk rises as the number of daily medicines grows ². Ask for a review rather than making changes yourself. Alcohol belongs in this paragraph too.

The other quiet contributor is nutrition and vitamin D status, since deficiency affects both bone and muscle strength, and adequate calcium and vitamin D underpin everything else you do for bone ⁶.

What to do after a fall, including one that did not hurt

Tell someone clinical. A fall that produced nothing but an embarrassed laugh and a bruised palm is the most useful piece of information you will get all year, because it is the trigger for a proper assessment: strength and balance testing, blood pressure sitting and standing, vision, medication review, and a conversation about whether a bone density scan is due ².

Two extra flags worth naming. If you have lost height, or your back rounded noticeably, or you have had sudden unexplained back pain, mention it, because spinal compression fractures often happen without a dramatic fall and are frequently missed. And if you fell because your knee gave way rather than because you tripped, say those exact words, since a knee that buckles is its own diagnostic question and not just clumsiness.

I did not get steadier by being careful. I got steadier by getting stronger, which took months, felt undignified in the beginning, and is the only part of this I would not now give up.
