Buckling Knee Physiotherapy

Experiencing the knee ‘giving way’ (aka buckling knee) is actually a pretty common complaint by athletes who have twisted their knees in sports like basketball, netball, soccer or badminton. Or just have had a bad fall on the knee.

This experience of your knee ‘giving way’ is an indication that you might have torn your anterior cruciate ligament (ACL) located deep inside your knee.

Our anterior cruciate ligament is a very strong rope-ligament located between the knee-joint (refer to the image above), and it's #1 responsibility is to block and limit the forward movement (anterior translation) of our leg bone (tibia) on our thigh bone (femur).

So when athletes and sports enthusiasts change direction quickly during games, what happens is that their knee is subjected to a very powerful, inward twisting motion. 

This loads and strains the anterior cruciate ligament a lot, and increases the risk of tearing...and ACL tears happen when the knee is force downwards and inwards beyond the ligament’s ability to hold the strain and load.

Athletes (and anyone) who had experienced a 100% ACL rupture (torn) often report hearing a ‘pop’ on injury. For partial tears, at most an experience of tearing.

Solving the buckling knee Problem

Unfortunately, the torn anterior cruciate ligament doesn’t heal on its own due to the poor blood supply to the ligament (also if it's 100% torn already, it needs to be repaired surgically by tying the torn parts together). Often, ACL surgeries would involve your ACL having to be reconstructed surgically by using either your hamstring tendon or patella tendon.

Physiotherapy and knee rehabilitation after surgery will normally takes about 6-9 months before the athlete is able to go back to full training. For most regular non-sports patients, 3 months of rehab to basic normal life, but for active living and sports, at least 6 months.

That being said, there are about 20% of people with ACL tears who are able to go about their day-to-day activities without having their ACL reconstructed. 

To cope with life of injured ACL without surgery, the following muscles need to have good strength and control:

  • Hamstrings (behind the thigh muscles)
  • Quadriceps (front of thigh muscles)
  • Gluteus Medius (buttock muscles)
  • Gastrocneumius (calf muscles)

Besides doing ongoing strengthening exercises, we recommend that you slowly ease back into sports specific training is essential. This is so that your muscles can develop an anticipatory reaction (feed-forward mechanism) to prevent injury.
