Knee Pain

There are several factors that can cause knee pain. Knee pain can be either referred pain or related to the knee joint itself.

About Knee Problems

Knee problems happen when you injure or develop disease in your knee and it can't do its job.

Your knee is the joint where the bones of the upper leg meet the bones of the lower leg, allowing hinge-like movement while providing stability and strength to support the weight of your body. Flexibility, strength, and stability are needed for standing and for motions like walking, running, crouching, jumping, and turning.

What are joints?

The point at which two or more bones are connected is called a joint. Several kinds of supporting and moving parts, including bones, cartilage, muscles, ligaments, and tendons, help the knees do their job....Read more about Knee Problems

Major Trauma: Assessment and Initial Management

This guideline provides guidance on the assessment and management of major trauma, including resuscitation following major blood loss associated with trauma. For the purposes of this guideline, major trauma is defined as an injury or a combination of injuries that are life-threatening and could be life changing because it may result in long-term disability. This guideline covers both the pre-hospital and immediate hospital care of major trauma patients but does not include any management after definitive lifesaving intervention. It has been developed for health practitioners and professionals, patients and carers and commissioners of health services.

Pain control using local anaesthetics to improve surgical results after shoulder, hip and knee replacement surgery

Doctors can use regional analgesia (injection of local anaesthetics near the nerves or the surgical site) rather than conventional pain control after surgery. Does this choice improve long‐term function after elective major joint (knee, shoulder and hip) replacement? We conducted this systematic review to explore controversy about the use of regional analgesia amidst efforts to limit healthcare costs and demonstrate value for interventions.

Knee braces, sleeves or straps for treating anterior knee pain (patellofemoral pain syndrome)

Patellofemoral pain syndrome (PFPS) is a painful knee condition that frequently affects young, physically active people. It is characterised by pain either to the front of the knee or behind the patella (knee cap). It is suggested that this may be caused by faulty alignment of the knee cap during knee movements. To help, some physiotherapists provide or people may purchase knee braces, sleeves or straps (termed 'orthoses') believed to correct this faulty alignment.

Morphine injections for pain relief after knee arthroscopy

Knee arthroscopy is a surgical procedure on the knee. The surgery is minimally invasive, which means that only a small cut (incision) is needed. An examination, and sometimes treatment, of damage is performed using an arthroscope, which is inserted into the joint through the small incision. Knee arthroscopy is used to assess or treat many orthopaedic (musculoskeletal) conditions, and patients may have pain after surgery. Morphine injected directly into the knee (intra‐articular morphine) to relieve pain has been widely studied, but we do not know how well it works.

Terms to know

Joints
In medicine, the place where two or more bones are connected. Examples include the shoulder, elbow, knee, and jaw.
Ligaments
Band of fibrous tissue connecting bone to bone or cartilage to bone thereby supporting or strengthening a joint.
Muscles
Muscles function to produce force and motion. They are primarily responsible for maintaining and changing posture, locomotion, as well as movement of internal organs, such as the contraction of the heart and the movement of food through the digestive system.
Referred Pain
A type of pain that is perceived in an area away from the site where the pain arises, such as a throat problem generating referred pain in the ear.
Tendons
Tough, fibrous, cord-like tissue that connects muscle to bone or another structure, such as an eyeball. Tendons help the bone or structure to move.
