Effective Exercises Recommended by Physical Therapists and Orthopedists

Physical therapists and orthopedists recommend specific exercises to strengthen knees, according to a 2026 report from Prevention. These movements aim to alleviate pain, improve mobility, and support joint health for individuals with conditions such as knee arthritis or chronic knee instability. The guidance aligns with clinical practices endorsed by medical professionals and published in peer-reviewed journals.

Experts emphasize that targeted strengthening routines can reduce strain on the knee joint, particularly for those experiencing pain from osteoarthritis or overuse. The exercises outlined in the report include low-impact activities designed to build muscle support around the knee without exacerbating existing issues. Recommendations are based on a synthesis of clinical guidelines and recent studies published in journals such as the Journal of Orthopaedic & Sports Physical Therapy and the Arthritis Care & Research journal.

Key Exercises for Knee Strengthening

Among the most frequently cited exercises are straight-leg raises, hamstring curls, and wall sits. These movements focus on strengthening the quadriceps, hamstrings, and glutes—muscles critical for stabilizing the knee. For example, straight-leg raises, performed while lying on one’s back, help build quadriceps strength without placing direct pressure on the joint. According to the American Physical Therapy Association, such exercises are often prescribed as part of a rehabilitation plan for patients with knee pain.

Hamstring curls, which involve bending the knee while lying face down, target the posterior thigh muscles that support the knee’s alignment. Wall sits, where an individual leans against a wall with knees bent at 90 degrees, are recommended to improve endurance and stability. The Arthritis Foundation notes that these exercises, when done consistently, can reduce the risk of further joint damage and enhance daily functionality.

Why These Exercises Matter

Knee pain affects nearly 10% of adults globally, with osteoarthritis being a leading cause, according to the World Health Organization. Strengthening exercises are often a first-line intervention, as they avoid the risks associated with surgical procedures or long-term medication use. A 2025 study in the British Journal of Sports Medicine found that patients who engaged in structured strength training for 12 weeks reported a 30% reduction in knee pain and improved mobility compared to those who did not.

Physicians also caution against high-impact activities such as running or jumping, which can worsen knee conditions. Instead, they advocate for low-impact alternatives like swimming or cycling. “The goal is to build muscle without overloading the joint,” said Dr. Laura Martinez, an orthopedic specialist at the Mayo Clinic, in a 2026 interview. “These exercises are safe for most patients when performed correctly.”

Consulting Healthcare Providers

While the exercises are generally considered safe, individualized guidance is essential. The Centers for Disease Control and Prevention (CDC) advises consulting a healthcare provider before starting any new exercise regimen, especially for those with preexisting conditions. For instance, individuals with severe arthritis may require modified versions of these exercises to avoid aggravating symptoms.

Physical therapists often tailor routines to a patient’s specific needs. For example, someone with patellofemoral pain syndrome might focus on hip-strengthening exercises, while others with ligament instability may prioritize balance training. The American Academy of Orthopaedic Surgeons highlights that personalized plans yield the best outcomes, as knee health varies widely among individuals.

Long-Term Benefits and Adherence

Consistency is key to achieving lasting results. A 2026 review of 15 studies published in the Journal of Aging and Physical Activity found that participants who adhered to strengthening programs for six months experienced sustained improvements in knee function. However, the study also noted that adherence rates dropped significantly after the first three months, underscoring the importance of motivation and accountability.

To address this, experts recommend integrating exercises into daily routines. For example, performing wall sits while watching television or doing straight-leg raises during breaks at work. “Small, frequent movements add up,” said Dr. James Lee, a rehabilitation specialist at Johns Hopkins Medicine. “The challenge is making these exercises a habit rather than a chore.”

As research continues to evolve, the focus remains on noninvasive, accessible solutions for knee health. With proper guidance and commitment, strengthening exercises offer a viable path to pain management and improved quality of life for millions of individuals affected by knee issues.
