Obesity Is Driving A Rise In Knee And Hip Surgeries, According To Doctor

Obesity is not just about how waist size or BMI, but it’s now reshaping the kinds of injuries patients are coming to orthopedic clinics. According to Dr. Rakesh Mattoo, Director of Orthopedics &amp; Joint Replacement at Max Smart Super Speciality Hospital, Saket, the link between weight gain and joint degeneration is now impossible to ignore. “In India, cases of obesity-related osteoarthritis have increased by 30–35 percent over the last ten years, especially in urban areas,” he explains.

Orthopedic surgeons are seeing the consequences every day. “Approximately 55–60% of our knee replacement patients are now overweight or obese, up from about 35–40% a decade ago,” Dr. Mattoo shares. A similar pattern exists with hip replacements: obesity now accounts for nearly 28–30% of those cases, compared with 15% in 2010. The physics behind this trend are sobering, studies show that “every 5 kg of extra weight increases the load on the knees by approximately 15–20 kg,” accelerating cartilage wear and hastening surgical intervention.

These clinical numbers reflect a far larger population trend. India’s burden of obesity has been rising steadily for decades. In 2022, around 70 million adults in India were classified as obese, including 44 million women and 26 million men, according to data published in The Lancet. This marks a sharp rise from the early 1990s, when obesity rates were much lower. Overall, obesity prevalence climbed from 1.2% to 9.8% in women and 0.5% to 5.4% in men between 1990 and 2022. Additionally, overweight and obesity together affect nearly one in four Indian adults, nearly 24% of women and 23% of men aged 15–49, and even children are showing increases in overweight prevalence. 

It’s not just body weight that matters, but where fat is stored. Central abdominal fat, that stubborn belly, is one of the greatest predictors of early joint degeneration, says Dr. Mattoo. And certain groups are at especially high risk: women (particularly post-menopausal), people with prior knee injuries, those with family histories of osteoarthritis, and individuals leading sedentary lives. Conditions like diabetes, hypothyroidism, and metabolic syndrome also create a kind of chronic internal inflammation that accelerates cartilage breakdown.

So what can someone do to protect their joints before they reach the operating table? Dr. Mattoo emphasizes realistic, sustainable steps:

Keep weight in check: Even losing 5–10% of body weight can significantly ease stress on knees and slow osteoarthritis progression.

Build strength: Strengthening the muscles around the thigh, hip, and knee, along with the core, helps distribute load and protect joints. Moderate, low-impact activities like walking, cycling, or swimming are far kinder to joints than high-impact exercise.

Eat smart: “Choose joint-friendly nutrition,” he urges, including foods rich in omega-3s, calcium, vitamin D, and protein, all essential for healthy muscle and cartilage.

Don’t rush into high-impact activity: Running, jumping, or poorly executed gym movements may feel energizing but can do more harm than good if your body isn’t prepared.

Get routine screening: Annual check-ups — including BMI, vitamin D levels, blood glucose, and lipid profiles — catch early risk factors so that preventive measures can be taken.

Looking at younger adults, building strong musculature between ages 20–35 isn’t vanity — it’s protection. Dr. Mattoo points out that muscle mass helps slow degenerative joint changes over decades. Simple habits like walking 6,000–10,000 steps a day, practicing correct posture, and avoiding harmful sitting patterns or lifting techniques go a long way.

With air pollution keeping many indoors, lifestyle changes have to adapt. Structured home workouts like resistance bands, yoga, or bodyweight exercises can mimic outdoor benefits. Even small changes — standing desks, walk-and-talk phone calls, frequent stretch breaks — increase daily calorie burn and reduce sedentary strain.

The rising tide of obesity isn’t just a statistic; it’s now manifesting in the everyday pain and movement limitations of millions of Indians. But as Dr. Mattoo reminds us, “It’s never too early or too late to make changes that protect your joints and your future mobility.”
