Cartilage Damage in the Knee: Symptoms, Diagnosis, and Treatment Options

What is knee cartilage damage and how is it recognised?

Knee cartilage damage occurs when the smooth tissue lining the joint surfaces wears away or tears, causing pain, swelling, and reduced mobility. Deccan Hardikar Hospital in Pune provides specialist diagnosis and treatment for chondral lesions and related knee injuries through its dedicated Arthroscopy and Sports Injury programme.

Cartilage does not contain blood vessels, which means it has a limited capacity to heal on its own. Early recognition of symptoms and timely clinical assessment are essential to prevent progressive joint deterioration.

Note: Knee cartilage damage can affect people of all ages — from athletes with acute sports injuries to older adults with gradual wear. Accurate diagnosis determines the right treatment path.

How do I know if I have knee cartilage damage?

Symptoms of knee cartilage damage vary depending on the location and severity of the injury. Common presentations include:

  • Pain during or after activity — particularly when climbing stairs, squatting, or kneeling
  • Swelling — the knee may feel puffy or warm, especially after physical activity
  • Stiffness — reduced range of motion, especially after rest
  • Clicking, grinding, or catching sensation — a mechanical feeling inside the joint during movement
  • Locking or giving way — the knee may buckle unexpectedly or feel unstable
  • Localised tenderness — pain when pressing on specific areas around the joint line

Symptoms may develop gradually from repetitive stress or appear suddenly following a sports injury or fall. Mild damage may produce only intermittent discomfort, while advanced chondral lesions can cause persistent pain at rest.

Warning: If your knee locks completely, swells rapidly after an injury, or you are unable to bear weight, seek medical attention promptly. These signs may indicate a significant structural injury requiring urgent evaluation.

How is knee cartilage damage diagnosed?

Accurate diagnosis of a chondral lesion requires a combination of clinical examination and imaging. At Deccan Hardikar Hospital in Pune, the orthopaedic team uses a structured diagnostic approach:

Diagnostic StepWhat It Reveals
Clinical ExaminationRange of motion, joint-line tenderness, stability tests
X-RayJoint space narrowing, bony changes; cartilage itself is not visible
MRI ScanDetailed view of cartilage thickness, tears, and associated soft-tissue injury
Diagnostic ArthroscopyDirect visualisation of cartilage surface; gold standard for grading lesions

Cartilage damage is graded on a scale from Grade I (surface softening) to Grade IV (full-thickness loss down to bone). The grade directly influences the treatment plan recommended by the surgeon.

For patients with a history of sports activity, the team also evaluates for concurrent injuries such as ligament tears or meniscal damage, which frequently accompany chondral lesions. Learn more about arthroscopy and sports injury care at Deccan Hardikar Hospital.

What is the best treatment for knee cartilage damage?

Treatment depends on the grade of cartilage damage, the patient's age, activity level, and whether other structures in the knee are affected. Options range from non-surgical management to surgical cartilage repair or joint replacement.

Non-Surgical (Conservative) Treatment

  • Physiotherapy and targeted knee cartilage repair exercises to strengthen surrounding muscles and reduce joint load
  • Anti-inflammatory medications to manage pain and swelling
  • Activity modification and weight management to reduce mechanical stress
  • Intra-articular injections (corticosteroid or hyaluronic acid) for symptom relief in appropriate cases

Surgical Treatment Options

  • Arthroscopic debridement and lavage — removal of loose cartilage fragments and joint washout
  • Microfracture — stimulates the bone marrow to produce repair tissue over the damaged area
  • Autologous Chondrocyte Implantation (ACI) — cartilage cells are harvested, cultured, and reimplanted
  • Osteochondral grafting (mosaicplasty) — healthy cartilage plugs are transplanted to the damaged site
  • Knee replacement — considered for advanced, full-thickness cartilage loss with significant joint degeneration

The sports injury arthroscopy programme at Deccan Hardikar Hospital addresses cartilage lesions alongside ligament and meniscal injuries, allowing combined procedures where clinically appropriate. For patients with end-stage cartilage loss, knee replacement surgery is available through the hospital's joint care team.

Note: Knee cartilage repair without surgery is effective for low-grade lesions in younger, active patients. Higher-grade damage or persistent symptoms despite conservative care typically requires surgical intervention.

How long does cartilage damage in the knee take to heal?

Recovery timelines vary considerably based on the treatment chosen and the severity of the cartilage injury.

TreatmentApproximate Recovery Time
Conservative management6–12 weeks for symptom improvement
Arthroscopic debridement4–8 weeks to return to light activity
Microfracture3–6 months; full sport return may take 9–12 months
Osteochondral grafting / ACI9–18 months for full recovery
Knee replacement6–12 weeks to independent walking; full recovery 3–6 months

Structured physiotherapy is a critical component of recovery after any cartilage procedure. Adherence to the rehabilitation programme directly influences the quality and durability of the outcome. Walking is generally encouraged early in recovery, but the intensity and timing are guided by the treating surgeon based on the specific procedure performed.

When should you see a doctor for knee cartilage damage?

Consult an orthopaedic specialist if you experience any of the following:

  • Knee pain that persists for more than 4 weeks despite rest and over-the-counter pain relief
  • Swelling that does not resolve within 48–72 hours after a knee injury
  • A locking or catching sensation that limits normal movement
  • Inability to fully straighten or bend the knee
  • Knee giving way during everyday activities such as walking or climbing stairs
  • Pain that wakes you from sleep or is present at rest

Delaying assessment of significant cartilage damage allows the lesion to progress. Grade I–II lesions that respond well to conservative treatment may advance to Grade III–IV if left untreated, at which point surgical options become more complex and recovery more prolonged. Early intervention preserves more of the native joint.

FAQs

  • Yes, knee cartilage damage can be treated, though the approach depends on the severity. Low-grade lesions often respond to physiotherapy and activity modification. Higher-grade damage may require arthroscopic surgery, cartilage grafting, or, in advanced cases, knee replacement. Early diagnosis improves the range of treatment options available and the likelihood of preserving the natural joint.
  • Cartilage has limited self-repair capacity because it lacks a direct blood supply. Minor surface damage may stabilise with conservative treatment — rest, physiotherapy, and anti-inflammatory medication. However, full-thickness cartilage loss does not regenerate naturally. Surgical intervention is typically required for significant chondral lesions to restore joint function and prevent further deterioration.
  • The meniscus is a C-shaped fibrocartilage disc that acts as a shock absorber between the thigh and shin bones. Articular cartilage lines the bone surfaces themselves. Both can be injured separately or together. A meniscus tear often causes joint-line pain and a clicking sensation, while articular cartilage damage tends to produce a grinding feeling and pain with weight-bearing activity.
  • Arthroscopy is recommended when symptoms persist despite 3–6 months of conservative treatment, when imaging suggests a significant chondral lesion, or when a mechanical symptom such as locking indicates loose cartilage fragments within the joint. It is also used diagnostically to grade lesions accurately and therapeutically to perform debridement, microfracture, or cartilage grafting in the same procedure.
  • Recovery varies by procedure. Arthroscopic debridement typically allows return to light activity within 4–8 weeks. Microfracture requires 3–6 months before return to sport. Osteochondral grafting or autologous chondrocyte implantation may take 9–18 months for full recovery. All procedures require structured physiotherapy. Your surgeon at Deccan Hardikar Hospital will provide a personalised rehabilitation timeline.
  • Untreated cartilage damage tends to progress over time. A Grade I–II lesion can advance to Grade III–IV full-thickness loss, leading to bone-on-bone contact, chronic pain, and significant functional limitation. This progression increases the likelihood of requiring more complex surgery, including knee replacement. Early assessment and appropriate management help preserve the joint and delay or avoid more invasive procedures.
