Male Andropause Joint and Muscle Pain: Why Your Knees Are Grinding

Why Your Joints Grind and Your Strength Fades

A 60-something man kneels down at a family memorial and hears his kneecap grind, followed by a sharp twinge. A man in his 50s finds he can no longer prop one foot on the opposite knee to trim his toenails because his hip is too stiff to hold the position. If you have ever typed "knee grinding sound," "shoulder won't loosen up," or "fingers stiff in the morning" into a search bar, it is worth looking past "just getting older" and considering male andropause (also called late-onset hypogonadism, a gradual decline in testosterone).

Male andropause is usually associated with fatigue, low libido, or low mood, but in clinical practice men frequently describe knees, shoulders, lower back, and finger joints all stiffening up around the same time, without any specific injury. Other whole-body signs of andropause are covered separately in Male Menopause Symptoms: A 10-Item Self-Check and Recovery Routine for Your 50s; this article focuses specifically on the joint and muscle pain piece and what to do about it.

The Slow Slide That Starts in Your Late 40s

Harman and colleagues (2001) analyzed blood samples from roughly 890 men in the Baltimore Longitudinal Study of Aging and found that total testosterone declines by about 1.6% per year after age 40, while free testosterone (the biologically active fraction) drops even faster, around 2 to 3% per year. A level of roughly 300 ng/dL in the late 30s can easily fall below 200 ng/dL by the 60s. Because the change unfolds over years without a single triggering event, most men chalk it up to "just age" until one day climbing stairs or lifting a grandchild suddenly feels much harder than it used to.

4 Ways Falling Testosterone Affects Joints and Muscles

Testosterone is not only involved in sexual function — it directly supports the building and maintenance of muscle, cartilage, tendon, and ligament tissue. As levels drop, four overlapping pathways pile stress onto the joints.

1. Muscle Mass Itself Declines (Sarcopenia)

A dose-response study by Bhasin and colleagues (2001) showed that muscle cross-sectional area and strength increased in proportion to the dose of testosterone administered. Read in reverse, this suggests that as testosterone naturally declines, the body's capacity to build new muscle also slows. Men typically lose about 1 to 2% of muscle mass per year after 40, and as that muscle thins out, the cushioning it once provided around the knees and shoulders weakens along with it. A 12-second self-check for sarcopenia is covered in Muscle Loss Aging.

2. Collagen Repair in Cartilage and Tendons Slows Down

Joint cartilage, tendons, and ligaments are built from collagen, and testosterone is one of the anabolic hormones (hormones that favor tissue building) that supports collagen synthesis. When levels fall, minor damage takes longer to repair — the stiffness that used to resolve in a day or two in your 30s can now linger for four or five days.

3. A Background of Low-Grade Chronic Inflammation

A study by Maggio and colleagues (2005) in older men found an inverse relationship between testosterone levels and interleukin-6 (IL-6), an inflammatory cytokine. In other words, lower testosterone tends to coincide with a low background level of inflammation sometimes called inflammaging, and under this condition, tissue around the joints may become more reactive to stress, lowering the pain threshold. That said, this was an observational study that did not establish direct causation, and the relationship between inflammatory markers and actual pain intensity varies considerably between individuals.

4. Weight Gain Compounds the Load on Joints

Many men gain 5 to 10 kg, mostly around the abdomen, as metabolism slows through andropause. The extra weight does not translate into joint load on a one-to-one basis — it compounds. A 70 kg man already loads his knees with roughly 3 to 4 times his body weight when descending stairs; add just 5 kg of body weight and the absolute force on the joint climbs by tens of kilograms.

Signs to Watch For — A Self-Check List

Joint and muscle pain linked to male andropause tends not to stay confined to a single joint. Instead, several areas tend to stiffen up around the same period.

Situations Men Commonly Describe

• A grinding or grating sound in the knee when bending it or walking down stairs, along with a sharp twinge
• Hip stiffness so pronounced that propping one foot on the opposite knee to trim toenails becomes difficult
• Trouble sitting cross-legged on the floor for more than 10 minutes without numbness setting in
• Finger joints so stiff on waking that making a fist takes 30 minutes or more to loosen up
• A twinge in the knee or wrist when picking up or setting down a grandchild
• Shoulder stiffness that a pain patch does not touch, and difficulty reaching behind the back or scratching between the shoulder blades
• A lower back that aches and is hard to straighten after just 30 minutes of gardening or yard work

Self-Check List

If three or more of the following apply, and you are also noticing other andropause symptoms such as low libido, fatigue, or low motivation, it is worth seeing a doctor for a testosterone test.

1. Stiffness has started in two or more of the knee, shoulder, and fingers at the same time, with no specific injury
2. Morning joint stiffness lasts more than 30 minutes after waking
3. Recovery time after the same level of activity has noticeably lengthened compared to a few years ago
4. Visible loss of muscle bulk in the arms or legs even without a change in exercise habits
5. Movements that require deep knee or hip flexion — stairs, squatting, sitting cross-legged — have become noticeably harder
6. Body weight has increased over the past 6 to 12 months while strength has seemingly declined
7. Other andropause symptoms — low energy, reduced libido, poorer sleep quality — are present as well

Warning Signs You Should Never Self-Manage

Joint and muscle pain from male andropause is typically gradual and bilateral (appearing similarly on both sides), and it usually improves with conservative management. But if any of the following apply, do not assume it is andropause and wait it out — see a doctor right away.

See a doctor immediately if:

• Pain is severe enough to wake you from sleep at night
• Unexplained weight loss accompanies the joint or muscle pain
• A joint becomes hot, swollen, and feverish
• You notice weakness or numbness in the legs, or sudden trouble controlling bladder or bowel function
• Severe pain follows a fall or impact and the area cannot be moved at all
• Sudden weakness affects only one arm or leg

These signs can point to conditions unrelated to andropause — septic arthritis, spinal nerve compression, tumors, or fractures. In these cases, an orthopedic or neurosurgical evaluation should come first, and self-directed strength training or NIR conditioning should wait until after a proper diagnosis.

A Step-by-Step Management Plan

Step 1: Confirm the Cause (Within 2 to 4 Weeks of Noticing Symptoms)

The first step is a fasting morning blood draw at a urology clinic to check total testosterone. Levels peak in the morning, so timing matters; testing is generally done before mid-morning, with a repeat test roughly two weeks later to confirm reproducibility. This stage should also screen for orthopedic issues — degenerative arthritis, rotator cuff tears — that can coexist with hormonal changes.

Step 2: Ease the Pain (During Flare-Ups)

• Adjust load, don't stop entirely: Rather than full rest, temporarily reduce the specific movements that trigger pain — deep squatting, lifting heavy loads.
• Heat and near-infrared care: Helps release muscle tension and improve local circulation, preparing the body for the exercise phase that follows.
• Prioritize sleep: Testosterone is released in concentrated pulses during sleep, particularly in the early morning hours, so consistently sleeping under 6 hours slows recovery.

Step 3: Address the Root Cause (Sustained Over 8 to 12+ Weeks)

• A resistance training program: The core tool for tackling both sarcopenia and joint instability together — follow the routine below 2 to 3 times a week.
• Weight management: Losing 1 kg reduces the absolute load on the knee during stairs and squatting by a larger multiple than the weight lost.
• Discuss hormone replacement therapy: If test results show a clearly low level and symptoms are significant, discuss the benefits and risks of testosterone replacement — including prostate and cardiovascular monitoring — with a urologist.

A Home Routine to Strengthen Joints and Muscles

The four exercises below require no special equipment and cover the knee, hip, shoulder, and lower back. Reduce intensity on days when pain is present, and if pain exceeds 3 out of 10, rest that day rather than progressing.

1. Chair Squat — Knee and Hip

Starting position: Stand with feet shoulder-width apart in front of a sturdy chair or sofa at knee height, toes turned slightly outward.

Movement: Push the hips back and lower slowly until you barely touch the seat, then stand back up. Keep the knees tracking over the second toe rather than caving inward.

Breathing: Inhale on the way down, exhale on the way up.

Reps and sets: Start with 8 to 10 reps x 2 sets, progressing to 12 reps x 3 sets once pain-free. Do this 3 times a week.

Common mistake: A large share of men in their 60s let their knees collapse inward during this movement, which distorts kneecap alignment and can worsen pain. Practicing in front of a mirror or against a wall helps correct the pattern.

2. Band Shoulder External Rotation — Shoulder

Starting position: Anchor one end of a resistance band to a doorknob or post, stand with the elbow bent 90 degrees and tucked against the side.

Movement: Keeping the elbow pinned to your side, slowly rotate the hand outward, then return to the starting position.

Breathing: Exhale as you rotate out, inhale as you return.

Reps and sets: 12 to 15 reps x 2 sets per side, 3 times a week.

Common mistake: The elbow drifts away from the side and the whole shoulder lifts, which shifts the work away from the rotator cuff and onto the upper shoulder muscles, reducing the exercise's effectiveness.

3. Bridge — Lower Back and Glutes

Starting position: Lie on your back with knees bent and feet hip-width apart.

Movement: Slowly lift the hips until the body forms a straight line from shoulders to knees, hold for 2 to 3 seconds, then lower.

Breathing: Exhale while lifting, inhale while lowering.

Reps and sets: 10 to 12 reps x 2 sets, 3 times a week.

Common mistake: Overarching the lower back rather than lifting through the glutes. Engage the abdominals lightly and focus on driving through the glute muscles instead.

4. Calf Raise — Ankle and Calf

Starting position: Stand holding a wall or table lightly for balance.

Movement: Rise onto the balls of the feet as high as possible, then lower slowly.

Breathing: Exhale while rising, inhale while lowering.

Reps and sets: 15 reps x 2 sets, 3 times a week.

Weekly Progression

Adding Near-Infrared Wellness Care to the Routine

Alongside the exercise routine above, near-infrared (NIR) care is sometimes used to support conditioning of muscles and joints before and after training. It is not a diagnostic or treatment tool for joint pain — it is more accurately understood as a wellness aid that helps you stick with your exercise routine.

The Basic Idea

• Cellular metabolism support: Near-infrared wavelengths are known to penetrate tissue beneath the skin and interact with cellular energy metabolism, an area studied under photobiomodulation research.
• Local circulation changes: A temporary increase in local blood flow, along with a sensation of warmth, is commonly reported at the treated site.
• Post-workout relaxation: Used to support a feeling of relaxation in the knee area or shoulder muscles that feel tight after chair squats or band exercises.

How to Work It Into the Routine

• Hold the device 5 to 10 cm from the skin and direct it at areas of stiffness — knee, shoulder, or lower back
• Apply for 10 to 15 minutes per area right after strength training
• It is more useful for ongoing conditioning during the recovery phase than during an acute flare-up
• It does not replace existing treatment or a clinician's instructions; if pain persists, see a specialist alongside using it

Everyday Habits That Protect Your Joints

Kneeling for Ceremonies and Holidays

Before kneeling, gently bend and straighten the ankles and knees about 10 times to warm up the joints. Placing a thin cushion or a folded towel under the knees reduces the direct pressure on the kneecap.

Floor Toilets and Sitting Cross-Legged

Squatting requires supporting your full body weight with the knees deeply bent, which places significant strain on knees and hips already weakened by andropause-related muscle loss. If you regularly need to use a floor-style toilet, the alternative positions covered in Squatting Over a Floor Toilet: Knee Strain and Practical Alternatives are worth reviewing. Limit cross-legged sitting to under 10 minutes at a stretch, switching leg positions partway through.

Gardening and Farm Work

Use a low stool or knee cushion instead of squatting for extended periods, and stand up to stretch the back and knees every 20 to 30 minutes. When lifting something heavy, bend the knees rather than the back.

Caring for Grandchildren

When picking up a child, avoid lifting with the back alone — bend the knees, bring the child close to your body, and stand up using leg strength. Practical ways to manage joint pain while caring for grandchildren are covered in Grandparent Childcare: Knee and Wrist Joint Pain Care.

A Long-Term Strategy to Slow the Decline

Joint and muscle pain tied to male andropause rarely disappears entirely — but how well it is managed makes a substantial difference to how quickly it progresses.

Maintaining Strength

• Continue resistance training 2 to 3 times a week for at least 12 weeks even after pain resolves.
• Build weight-bearing activity — stair climbing, light hiking — into daily life to slow the rate of muscle loss.
• Time how long it takes to stand up from a chair 5 times every 6 months to track strength changes.

Hormonal and Metabolic Management

• Include a testosterone check in your annual physical to track the trend over time.
• Monitor body weight and waist circumference regularly to keep abdominal fat from accumulating.
• Aim for 6 to 7 hours of sleep or more to support hormonal rhythms.

Periodic Review

• When starting a new activity or exercise, keep intensity low for the first 2 to 3 weeks.
• Keep a log of which specific movements repeatedly trigger joint sounds or stiffness — this is useful information for a doctor.

Common Myths, Corrected

"It's just aging — no need to see a doctor"

→ Natural aging changes and changes that can be slowed through testing and management are two different things. If several joints are stiffening up at once, a workup that includes a testosterone test can help narrow down the cause.

"A pain patch takes care of muscle aches"

→ Pain patches offer temporary relief but do not address the underlying cause of sarcopenia — the actual loss of muscle mass. Rebuilding muscle through resistance training is also required.

"Testosterone replacement therapy will make the joint pain disappear immediately"

Snyder and colleagues (2016) reported physical-function results from the Testosterone Trials showing modest improvements in measures like walking distance in older men after replacement therapy, but the improvements were small, and the study was not designed to target joint pain specifically. Replacement therapy may be one option worth discussing for strength and overall condition, but there is not yet sufficient evidence to treat it as a therapy that immediately eliminates joint pain.

"A grinding joint sound means the cartilage is wearing away"

→ In the absence of pain, a grinding or grating sound in a joint is usually not clinically significant on its own. It becomes a sign worth checking out when it appears alongside pain, swelling, or restricted movement.
