Safe and effective high-intensity interval training

High-intensity interval training alternates short bursts of hard effort with recovery, boosting aerobic fitness, heart health, and muscle in less time. For older adults, adjusting intensity to current fitness levels helps keep HIIT safe and effective.

Obesity appears not to raise risks from shoulder replacement surgery

Obesity is thought to increase the risk of complications for people undergoing certain joint replacement surgeries. A 2025 study found that compared with people of a healthy weight, people with severe obesity (BMI of at least 40) were at no greater risk for serious complications following shoulder replacement surgery.

Acupuncture boosts pain relief for chronic low back pain

Chronic low back pain affects as many as one-third of adults ages 65 and older and can be difficult to treat. A 2025 study found that adding 12 weeks of acupuncture to usual care resulted in greater pain relief and better function that lasted as long as a year after the treatments.

Two bad knees? What to know about bilateral knee replacement

If total knee replacement is needed for both knees and symptoms in both are equally severe, bilateral knee replacement can be done, either in one surgery or in stages. Replacing both knees at once may be a good option for people under 75 with no major medical conditions and support at home.

Gait training may relieve pain from knee osteoarthritis

In a 2025 study, people with knee osteoarthritis reported less pain and had less knee cartilage damage after changing their walking gait to reduce pressure on the inner part of the knee.

Building stronger legs

Leg strength becomes even more vital as people age, as the legs are essential for routine movements such as going up and down stairs, sitting and rising from chairs, bending over and standing up, and protecting against falls. The main leg muscles are gluteals, quadriceps, hamstrings, and calves. Some exercises that can help strengthen these muscles are bridges, step-ups, and heel raises.

What happens when a joint replacement fails?

Total knee and hip replacements are highly successful procedures that can relieve pain and restore mobility for people with severe arthritis. Occasionally, joint replacement fails, and revision surgery is needed. Reasons for revision include infection, implant loosening, dislocation, and fracture. Warning signs of a problem include persistent pain, swelling, or instability. Revision surgeries are more complex, require longer recovery, and carry higher risks than the original surgery. Experienced surgeons who perform these procedures frequently tend to have the most success.

Walking, cycling, and swimming are best exercises for knee osteoarthritis

An analysis of 217 trials found that lower-impact aerobic exercise (walking, cycling, and swimming) is most effective for easing knee osteoarthritis pain and improving function. Other exercise types, such as flexibility, mind-body, neuromotor, and strengthening, also offer benefits.

What to do about pain "down there"?

Chronic pelvic pain-medically known as chronic prostatitis / chronic pelvic pain syndrome, or CP/CPPS-is one of the more common and challenging conditions older men face. Because the underlying cause may not be identified, doctors often take a trial-and-error approach to managing the common symptoms like throbbing, aching pain, urination problems, and sexual dysfunction. Options include different types of medication, physiotherapy, shock wave therapy, and aerobic exercise.
