Six Ways to Help Manage Knee Arthritis and Stay Active
Knee Arthritis Treatment in Portsmouth, NH: 6 Ways to Stay Active Without Injections or Surgery
Knee arthritis is one of the most common forms of osteoarthritis, affecting more than 80% of osteoarthritis cases and nearly 19% of Americans over age 45. Here in Portsmouth, NH and across the Seacoast region, we see it every day – active adults who want to keep walking, hiking, golfing, skiing, and staying independent without being limited by chronic knee pain.
For many people, a diagnosis of knee osteoarthritis leads to chronic, debilitating knee pain that stops them from doing their favorite activities. Sometimes it is due to the limiting belief that once you have arthritis, you have “bad knees” for life. Other times it is because you have been told you have “bone-on-bone” in your knee and should scale back activity so you do not make it worse.
This line of thinking is flawed and often leads to unnecessary injections, procedures, and surgery. Being active is one of the best things you can do to manage knee arthritis and protect your joints long term.
But what if movement and activity hurt?
Here are six expert-backed strategies we use at our Portsmouth, NH physical therapy clinic to help people manage knee osteoarthritis naturally and stay active without relying on injections or surgery.
1. Strengthen Your Hips and Core
If your hips and core are weak, your knees take the hit.
Your thigh bone (femur) connects your knee to your pelvis. Your core strength controls your pelvis. If your pelvis is not stable, your femur struggles to stay in proper alignment, which increases stress through your knee joint.
At our Portsmouth physical therapy clinic, we prioritize hip and core strengthening for patients with knee arthritis because improving these areas often significantly reduces knee pain. If you have arthritis in your knees, minimizing unnecessary joint stress is critical. Strong hips and a stable core help prevent flare-ups and keep you active longer.
2. Keep Your Knees Mobile
Mobility before stability is a principle we emphasize with every joint, but especially the knee.
Your knee needs to bend fully so you can squat and pick things up, and it needs to straighten fully to provide stability when walking. When either of these motions is limited, surrounding muscles and ligaments absorb more stress, which can aggravate arthritis symptoms.
Many people in the Seacoast area are told that stiffness is simply part of arthritis and something they must accept. But even a 10 percent improvement in knee mobility can create meaningful functional gains, reduce daily discomfort, and help you avoid more invasive treatments.
Limited motion is often treatable – even with arthritis.
3. Do Not Stop Your Activities
When people hear they have arthritis, especially if they have been told it is “bone-on-bone,” they often think slowing down will protect their knees. In reality, inactivity can make symptoms worse.
Research consistently shows that severe joint pain among adults with arthritis is worse with inactivity. Movement improves blood flow, maintains joint nutrition, and preserves muscle strength.
Interestingly, only about 15 percent of patients with evidence of knee osteoarthritis on X-ray report symptoms. That means many people are walking, biking, hiking around Portsmouth, and enjoying their favorite activities despite what imaging shows.
The key is smart activity, not no activity. Continuing to move is one of the most powerful ways to prevent arthritis from progressing and to maintain independence as you age. If pain is limiting you, working with a knee pain specialist in Portsmouth, NH can help you modify activities safely and effectively.
4. Optimize Your Footwear and Walking Mechanics
Your feet have a direct impact on your knees. If you wear unsupportive shoes or walk with poor mechanics, your knees absorb more stress than they should.
Over time, this increased strain can worsen arthritis symptoms. Supportive footwear that promotes proper alignment and cushioning can reduce unnecessary joint loading.
Walking is one of the best low-impact activities for knee arthritis. If you experience knee pain while walking around Portsmouth or on local trails, a professional gait assessment can identify weaknesses or imbalances contributing to your discomfort and help you choose footwear that supports your specific needs.
5. Choose Natural, Joint-Friendly Pain Relief Options
Your knees work hard every day. If you have arthritis, finding relief without relying on medications, injections, or surgery can be life changing.
Natural pain relief strategies can help reduce inflammation and improve mobility. Heat therapy and targeted stretching reduce stiffness by increasing circulation and relaxing surrounding muscles. Massage and foam rolling improve blood flow and ease muscle tension around the knee.
Regenerative treatments such as shockwave therapy, EMTT, and dry needling are becoming popular alternatives to cortisone injections. These approaches stimulate your body’s natural healing response rather than masking pain or contributing to long-term joint breakdown.
When used appropriately, these strategies can help you manage knee arthritis while staying active and avoiding unnecessary procedures.
6. Manage Inflammation with Diet and Hydration
Chronic inflammation can worsen arthritis symptoms, but nutrition plays a significant role in joint health.
Anti-inflammatory foods such as fatty fish, leafy greens, berries, and turmeric support joint function. Omega-3 fatty acids from fish oil may reduce inflammation at a cellular level. Supplements like collagen and glucosamine-chondroitin may support cartilage health and joint lubrication for some individuals.
Hydration is equally important. Water helps maintain joint cushioning and reduces friction within the joint.
Simple dietary changes combined with appropriate supplementation can complement your physical therapy program and support long-term knee health.
Final Thoughts on Knee Arthritis Treatment in Portsmouth, NH
Even if you have been told you have “bone-on-bone” or advanced arthritis, you can still improve your knee health.
The best thing you can do for your knees is to keep moving. The right strength program, improved mobility, supportive footwear, smart activity modification, and natural pain relief strategies can make a significant difference.
