ACL Injury

An ACL (Anterior Cruciate Ligament) injury is a tear of one of the major stabilising ligaments in the knee, common in sports involving sudden stops, jumping, and direction changes.

ACL Injury

Symptoms

  • Loud pop at the time of injury
  • Rapid swelling within hours
  • Severe pain and inability to continue activity
  • Feeling of knee instability or giving way
  • Loss of full range of motion

Common causes

  • Sudden deceleration or stopping
  • Pivoting with foot firmly planted
  • Landing awkwardly from a jump
  • Direct blow to the knee
  • Female athletes at higher risk due to anatomy

How physiotherapy helps

Pre-surgical rehab focuses on reducing swelling, restoring ROM, and strengthening muscles. Post-surgical rehab follows a structured protocol over 6-9 months including progressive strengthening, proprioception training, and sport-specific drills.

Exercises your physiotherapist may give you

  • Quad sets and straight leg raises (early phase)
  • Heel slides for ROM
  • Mini squats and leg press
  • Balance board exercises
  • Step-ups and lunges (mid phase)
  • Running and agility drills (late phase)

Please note: start these exercises only after an assessment, and stop if pain increases. Your physiotherapist will choose the right exercises, number of repetitions and progression for you.
