Understanding Knee Degeneration & Arthritis: X-ray Findings Explained

What does “joint space narrowing” mean in a knee X-ray?

Joint space narrowing describes the reduction in the gap between the thigh bone (femur) and the shin bone (tibia). On an X-ray, this often indicates loss of cartilage — the smooth tissue that cushions the knee joint.

  • Implication: Suggests arthritis or “wear and tear.”

  • Treatment Options:

    • Regenerix Gold (joint health supplement to support cartilage)

    • Physiotherapy (at The Pain Relief Practice, Orchard Road)

    • Shockwave Therapy (for stimulation of repair)

    • HotHeal Therapy (manual + radiofrequency approach)

    • MRI (at The Pain Relief Clinic) if the degree of cartilage damage needs clearer assessment

What are “osteophytes” in the knee?

Osteophytes are bony spurs that develop along the edges of the joint. They form as the body’s attempt to stabilize the worn-out joint.

  • Implication: Often associated with stiffness, grinding sensation, and visible “knobbly” knees.

  • Treatment Options:

    • Non-surgical therapies like physiotherapy, shockwave, or HotHeal

    • Supplements like Regenerix Gold for long-term joint health

    • MRI can help exclude other causes such as meniscal tears

What is “subchondral sclerosis”?

This refers to increased bone density just beneath the joint surface. It develops as cartilage thins and more stress is transmitted to the bone.

  • Implication: A sign of moderate to advanced arthritis.

  • Treatment Options:

    • Targeted physiotherapy and strengthening

    • Shockwave Therapy to stimulate bone and soft tissue repair

    • Regenerix Gold for long-term cartilage and joint protection

    • MRI (Pain Relief Clinic) if symptoms are worse than X-ray suggests

What are “subchondral cysts”?

These appear as fluid-filled pockets in the bone beneath the joint surface. They occur due to microfractures and fluid seepage.

  • Implication: Suggests cartilage wear and ongoing joint stress.

  • Treatment Options:

    • Regenerix Gold (cartilage protection and joint health support)

    • Physiotherapy and HotHeal Therapy

    • MRI if pain is disproportionate, to assess for hidden cartilage or meniscal injuries

What is “patellofemoral joint arthritis”?

This is arthritis of the kneecap joint (patella meeting the femur). Patients often feel pain when climbing stairs, standing from sitting, or squatting.

  • Implication: May explain front knee pain even if other joint areas look normal.

  • Treatment Options:

    • Physiotherapy at The Pain Relief Practice for patellar tracking exercises

    • Shockwave Therapy or HotHeal Therapy for pain relief and tissue repair

    • MRI (Pain Relief Clinic) if cartilage loss is suspected behind the kneecap

What does “varus or valgus deformity” mean?

  • Varus deformity: Knees angling inward (bow-legged).

  • Valgus deformity: Knees angling outward (knock-kneed).

  • Implication: These deformities put uneven stress on the knee joint, speeding up arthritis progression.

  • Treatment Options:

    • Physiotherapy for gait and muscle balance

    • Shockwave or HotHeal for pain control

    • Regenerix Gold for long-term joint support

    • MRI (Pain Relief Clinic) for severity assessment before considering surgery

What is “meniscal calcification / chondrocalcinosis”?

This refers to calcium deposits in the meniscus (the shock absorber cartilage in the knee).

  • Implication: Associated with stiffness, catching sensation, or pseudo-gout.

  • Treatment Options:

    • Non-invasive therapies like physiotherapy, shockwave, HotHeal

    • Supplements like Regenerix Gold

    • MRI for meniscal integrity and other hidden injuries

What is a “suprapatellar effusion”?

This means fluid in the knee joint, often seen as a “swollen knee.”

  • Implication: Can occur with arthritis, injury, or inflammation.

  • Treatment Options:

    • Physiotherapy and shockwave for underlying causes

    • HotHeal Therapy for reducing pain and swelling

    • MRI (Pain Relief Clinic) to evaluate for ligament or cartilage injury

✅ Key Takeaway

X-ray findings such as joint space narrowing, osteophytes, sclerosis, cysts, and deformities point towards knee degeneration and arthritis. While these changes are common with age, timely treatment with non-surgical therapies (physiotherapy, shockwave, HotHeal) and supplements like Regenerix Gold can reduce symptoms and delay progression.

When symptoms are severe or unclear, MRI at The Pain Relief Clinic can give a more complete picture to guide safe, effective treatment.
