Knee Pain: What the Research Shows

Curated & reviewed by Dr. Nikolay Chernukhin, D.C.

Bottom line: For knee osteoarthritis, the strongest evidence supports exercise; hands-on chiropractic and manual therapy also reduce pain and improve function in the short term, and massage can add modest relief — none of these cure the arthritis, but all are safe, well-studied ways to hurt less and move better.

Knee pain from osteoarthritis is one of the most common reasons people struggle with stairs, walks, and simply getting through the day. Below is a plain-language look at what the research actually shows about the kinds of care we offer at our Vancouver, WA and Gresham, OR clinic — chiropractic and manual therapy, exercise and rehab, and massage. We've kept these summaries honest, including where the evidence is strong and where it is still limited.

Chiropractic & manual therapy

Effectiveness of manual physical therapy and exercise in osteoarthritis of the knee. A randomized, controlled trial

Deyle GD, et al. · Annals of Internal Medicine · 2000

In this small trial of 83 people, adding hands-on joint therapy to an exercise program cut knee pain and stiffness by about half, and the gains still held a year later.

Effects of orthopaedic manual therapy in knee osteoarthritis: a systematic review and meta-analysis

Anwer S, et al. · Physiotherapy · 2018

Pooling 11 trials, this review found hands-on joint therapy — alone or with exercise — eased knee pain and improved movement and function, mainly in the short term.

Effectiveness of Mobilization with Movement on the Management of Knee Osteoarthritis: A Systematic Review of Randomized Controlled Trials

Weleslassie GG, et al. · Pain Research and Management · 2021

A review of randomized trials found a hands-on 'mobilization with movement' technique improved knee pain, range of motion, and daily activities, though the studies were mostly short-term.

The effects of manual therapy in pain and safety of patients with knee osteoarthritis: a systematic review and meta-analysis

Zhu B, et al. · Systematic Reviews · 2024

This recent review of randomized trials found manual therapy significantly lowered knee-arthritis pain, with no serious side effects reported in the included studies.

Exercise & rehab

Exercise for osteoarthritis of the knee: a Cochrane systematic review

Fransen M, et al. · British Journal of Sports Medicine · 2015

This large, high-quality Cochrane review of 44 trials found land-based exercise gives a moderate drop in knee pain and better function that lasts at least 2 to 6 months after you stop.

Efficacy of strengthening or aerobic exercise on pain relief in people with knee osteoarthritis: a systematic review and meta-analysis of randomized controlled trials

Tanaka R, et al. · Clinical Rehabilitation · 2013

This review of randomized trials found that both muscle-strengthening exercise and aerobic exercise help relieve pain in people with knee osteoarthritis.

Massage & soft tissue

Massage therapy for osteoarthritis of the knee: a randomized controlled trial

Perlman AI, et al. · Archives of Internal Medicine · 2006

In this small trial of 68 adults, an 8-week course of Swedish massage lowered knee pain and improved function compared with people who got no treatment.

Massage Therapy for Pain and Function in Patients With Arthritis: A Systematic Review of Randomized Controlled Trials

Nelson NL, et al. · American Journal of Physical Medicine & Rehabilitation · 2017

Across 7 trials, this review found low- to moderate-quality evidence that massage beats no treatment for easing arthritis pain and some function, but stronger studies are still needed.

Frequently Asked Questions

Does chiropractic or manual therapy help knee osteoarthritis?

Yes — reviews of randomized trials show that hands-on joint therapy, especially combined with exercise, reduces knee pain and improves movement in the short term, with no serious side effects reported. It doesn't reverse the arthritis, but it can help you move more comfortably.

What exercises help knee osteoarthritis?

Both muscle-strengthening (especially the thigh and hip) and aerobic exercise like walking or cycling are proven to ease knee-arthritis pain. A large, high-quality Cochrane review found the benefit is moderate and lasts at least 2 to 6 months after you stop, so staying consistent matters.

Can massage help knee osteoarthritis?

It can help. A trial of Swedish massage lowered knee pain and improved function over 8 weeks, and reviews find massage beats no treatment — but the overall evidence is lower quality, so it works best as an add-on to exercise and hands-on care rather than a stand-alone cure.
