Knee and shoulder injuries are very common during accidents, physical traumas and falls, sports related activities and physical tasks at home etc. These injuries can be either acute or chronic depending upon the situation and type of injury.
Shoulder injuries occur due to lifting something very heavy or throwing a ball or pushing a heavy object. Shoulder joints are very flexible and usually most of our physical tasks rely on its joints, ligaments and muscles.
Here are some most common shoulder injuries:
Shoulder impingement syndrome
This injury is caused by the muscles of the rotator cuff which becomes impinged as they pass through the shoulder joint. Common names for this injury are thrower’s shoulder or swimmer’s shoulder.
This is the restricted movement of shoulder joint and causes stiffness and pain. Its causes can be long term disease like stroke or diabetes, injuries, overuse of muscles or limited use of muscle. The muscles around the shoulder become stiff and their movement becomes restricted. It can be treated with can killers and exercise.
AC (acromioclaviculor) joint separation
AC separation or AC sprain is an injury of ligament that holds acromioclaviculor joint together at the top of the shoulder. It is basically the separation of collar bone and shoulder blade. It is usually caused by falls or direct injury to this joint.
It is a traumatic and painful injury usually occurs during sports or from a fall. In this injury the upper arm bone pops out of the cup shaped socket of the shoulder blade.
Glenoid Labrum tear
The glenoid labrum is a fibrous ring of tissue which attaches to the rim of the glenoid shallow socket of the shoulder blade where the ball of the humerus or upper arm bone sits. The injury to this fibrous ring causes this problem and it is very painful.
Rotator cuff tear
A rotator cuff strain is a tear to any of the four muscles of the shoulder. These are the muscles which help in rotating the arm around the shoulder and provide a cuff to the joint. This injury can be mild or severe. It occurs in sports like throwing and racket sports.
Deltoid muscle strain
It is due to the injury of deltoid muscle. It causes pain at the front, side and back of the shoulder.
Similarly, knee injuries are also very common in chronic patients, physically active people and athletes. Some of these injuries are listed below:
This is the most common type of knee injury usually due to direct fall onto it or road accident. The knee cap (patella) or the ends of the femur or tibia can be fractured.
It occurs when the bones of the knee are out of place either completely or partially. The knee cap can be slip out of its place or the leg bones (tibia and femur) forced out of their alignment.
ACL (Anterior cruciate ligament) injury
This is caused by the tear in anterior cruciate ligament along with the da,age to other structures in the knee. It is common in athletes.
PCL (Posterior cruciate ligament) injury
It occurs due to posterior cruciate ligament tear usually due to road accidents. It often injured from a blow to the front of the knee while the knee is bent. It is tend to be partial tears with the potential to heal on its own.
The tendons of the muscles in the knee joint can be torn or stretched. Anyone can get this injury but usually sports persons can get it. It is due to wrong positioning of the leg or knee.
It is the injury of the meniscus of the knee which provides cushioning to the knee joint and its structures. It causes swelling and severe pain in knee. The sudden twisting, cutting and pivoting during sports cause this injury. It also occurs in elderly people with wrong twisting of the knee.
The patella can dislocate laterally i.e. towards the outside of the knee. It is common in women. But it can be easily returned to the normal place by the straightening out the knee, usually resulting in kneecap popping into its place.
These are some common knee and shoulder injuries which can be treated when properly diagnosed. Otherwise, they can become chronic and severe.
