What is Dislocated Knee
A dislocated knee occurs when the position of the thighbone relative to the shinbone becomes disrupted at the knee joint. It can happen through trauma to your leg, like from falls, sports injuries, and car accidents.

What is a Multi-Ligament Knee Injury or 'Dislocated Knee'
‘Dislocated Knee’ Multi-ligament knee injury of the knee is also known or defined as a knee dislocation. If we look at a knee model, from the front, this is your kneecap, your femur or thigh bone, your tibia or shin bone.
The lateral or outside part of the knee, you’ve got the lateral collateral ligament. On the medial on inside part of the knee, is the medial collateral ligament. On the back of the knee you’ve got your posterior cruciate ligament.
And inside the knee, you have the anterior cruciate ligament. Those are the four ligaments that help provide stability to the knee. When you have a multi-ligament knee injury or a knee dislocation, it usually involves a combination of two, but usually three, ligaments being completely ruptured.
This is a significant injury. It usually requires transport to an emergency department. It is associated with nerve injury. It’s also associated with potentially a vascular injury, and therefore, when you have a knee dislocation or a multi ligament injury, you should go or bet transferred to the emergency department for investigation for those more serious injuries involving your nerves or the vessels around the knee joint.
Treatment for a multi-ligament or knee dislocation usually requires a period of hospitalization and stabilization of the knee with knee bracing. It may require acute surgical intervention to repair and reconstruct all the ligaments involved.
It may require vascular surgery to repair any vascular injury, or nerve surgery to potentially repair a major nerve injury that can be associated with this type of injury. If you don’t require surgery immediately, you will be discharged from hospital in a stabilizing knee brace.
You will likely need physiotherapy initially. Once you get through the acute phase of this sort of injury, and one that didn’t require surgery initially, you will likely require surgery at a later date to reconstruct those ligaments on a more elective basis. And this will involve tendon grafts or donated tendon grafts to reconstruct the multiple ligaments involved. Local Physiotherapist
If you suffered a multi ligament knee injury or have questions about this sort of injury, seek consultation with your family doctor or get a referral to an orthopedic surgeon. Local Physiotherapist.
What is Jumper's Knee
In jumper’s knee, or the other term for it is patellar tendinopathy, is a painful inflammatory condition involving the patellar tendon.
The patellar tendon is located in the front of the knee. It is the insertion between the distal pull of the patella into the tibia. Jumper’s knee particularly affects athletes in jumping sports such as basketball, volleyball, but not just limited to the jumping sports because it can also affect other athletes such as soccer players and weight lifters and even tennis players.
The symptoms of jumper’s knee or patellar tendinopathy are anterior knee pain particularly after activity or during activity. The degree of pain depends upon the severity of the illness or the chronicity of it. That is, how long it’s been there for.
In the early stages of jumper’s knee, a person might feel a little bit of pain, but oftentimes is relieved just with rest, ice, and taking some medications, and altering some of their activities. However, in severe cases, it can be very persistent throughout the activity and does not respond to rest, ice, and anti-inflammatories.
The treatment for patellar tendinopathy or jumper’s knee involves anti-inflammatory measures such as ice, compression, and the use of anti-inflammatory medications. It’s equally important to involve a physical therapist in the treatment of patellar tendinopathy as there are biomechanical factors that contribute to the condition such as hamstring and calf tightness and also in landing technique.
The role of a physical therapist would be to assess one’s abilities during jumping and landing and to help with rehabilitation in some of these techniques. Local Physiotherapist
In some instances, patellar tendinopathy is not responsive to conventional conservative therapies such as anti-inflammatories and physical therapy. In instances where patellar tendinopathy is not responsive then sometimes injection type therapies are indicated.
If you feel that your patellar tendinopathy is not being responsive, you should consult your local sports medicine physician.
