Back of Knee Pain

Pain at the back of the knee, also called posterior knee pain, is a common condition that can result from a variety of causes, including muscle, tendon, ligament, or joint issues. It can affect mobility, walking, sports performance, and daily activities. Early diagnosis is important to prevent worsening or chronic pain.

Back of Knee Pain

Common Conditions We Treat

Hamstring Tendonitis / Strain

Overuse or sudden stretching of the hamstring tendons near the knee can cause pain at the back of the knee, swelling, and difficulty bending the knee.

Baker’s Cyst (Popliteal Cyst)

A fluid-filled swelling behind the knee, often caused by underlying arthritis or meniscus injury. It can cause tightness, swelling, and sometimes limited knee movement.

Popliteal Muscle or Ligament Strain

The small muscles and ligaments at the back of the knee may be strained from overuse, twisting movements, or sudden impacts.

Meniscus Injury

A tear in the posterior part of the knee meniscus can sometimes present as pain behind the knee, especially when bending or twisting the joint.

Deep Vein Thrombosis (DVT)

Although less common, severe swelling, warmth, and tenderness at the back of the knee could indicate a blood clot. This is a medical emergency and requires urgent attention.

Symptoms of Posterior Knee Pain

  • Pain or tenderness at the back of the knee

  • Swelling or a noticeable lump (in cases like Baker’s cyst)

  • Stiffness, particularly when bending or straightening the knee

  • Pain during walking, running, or climbing stairs

  • Occasional popping or locking sensations

Diagnostic Assessment

  • Clinical examination to assess swelling, tenderness, and knee stability

  • Diagnostic ultrasound scan to identify cysts, tendon injury, or inflammation

  • MRI in selected cases for detailed assessment of ligaments, meniscus, or soft tissue

Accurate diagnosis is key to selecting the most effective treatment approach.

Treatment Options for Back of Knee Pain

Conservative Management

  • Rest and activity modification

  • Ice or heat therapy (under clinician guidance)

  • Anti-inflammatory medications (if appropriate)

Physiotherapy & Rehabilitation

  • Stretching and strengthening of hamstring, calf, and surrounding muscles

  • Joint mobilization and soft tissue therapy

  • Postural and gait correction

  • Guided home exercise programs

Injection Therapy

  • Ultrasound-guided corticosteroid injection for inflamed tendons or bursae

  • Aspiration or injection for Baker’s cyst in selected cases

Advanced Treatment

  • Surgery in severe cases (e.g., persistent cysts, tendon tears, or meniscus injuries)

  • Shockwave therapy for chronic tendon issues

Why Early Treatment Matters

Posterior knee pain can limit mobility, reduce activity levels, and affect daily life. Early intervention helps relieve pain, restore knee function, and prevent chronic problems or recurrent injuries.

Persistent pain at the back of the knee should be assessed by a qualified healthcare professional to create a personalised treatment plan.
