The hip joint is the largest weight-bearing
joint in the human body. It is also referred to
as a ball and socket joint and is surrounded
by muscles, ligaments, and tendons. The
thigh bone or femur and the pelvis join to
form the hip joint.
Hip replacement has become necessary
for your arthritic hip: this is one of the
most effective operations known and
should give you many years of
freedom from pain.
This means that part or all of your previous hip replacement needs to be revised. This operation varies from very minor adjustments to massive operations replacing significant amounts of bone and hence is difficult to describe in full.
The knee is a complex joint which consists of bone, cartilage, ligaments and tendons that make joint movements easy and at the same time more susceptible to various kinds of injuries.
A Total Knee Replacement (TKR) or
Total Knee Arthroplasty is a surgery
that replaces an arthritic knee joint with
artificial metal or plastic replacement
parts called the ‘prostheses’.
Revision Knee Replacement means that part or all of your previous knee replacement needs to be revised. This operation varies from very minor adjustments to massive operations replacing significant amounts of bone.
Unicondylar Knee Replacement simply means that only a part of the knee joint is replaced through a smaller incision than would normally be used for a total knee replacement.

Hip Muscle Injuries

Muscle strains are more common injuries in sports. Muscle strain refers to an injury of a muscle or its attaching tendons. A tendon is a tough, fibrous cord of tissue that connects muscles to bone. There are two types of muscle strains, acute strain and chronic strain. Acute strains are caused by excessive stretching or tearing of a ligament. Chronic strains are caused by repetitive movements of muscles and tendons over long periods of time.

Sports activities such as football, basketball, hockey, gymnastics, boxing, wrestling, tennis, rowing, golf-sports, racquet, throwing, and contact sports increases the risk of muscle injuries. The symptoms include pain, swelling, muscle spasm, muscle weakness, inflammation, and cramping.

A hamstring strain is an excessive stretch or tearing of hamstring muscles which are located at the back of the thigh. It is a common injury particularly seen in athletes who participate in sports activities that requires running, jumping, and kicking. During growth spurt the bones grow faster than the muscles. As a result the muscle becomes tight and a sudden jump or stretch can tear the muscle away from its connection to the bone resulting in strain.

In the severe case of hamstring strain a tendon can also be torn away from its bony attachment, which is called an avulsion injury.

Hamstring strain is usually caused when a muscle is stretched beyond its limit. Some of the factors that increase the risks of developing muscle strain include tight muscles, muscle fatigue, muscle imbalance, athletic activities, poor running technique and insufficient warm-up.

A person who experiences a muscle strain in the thigh will have a sudden sharp pain in the affected muscle. Sometimes a popping or snapping sensation is felt in the back of the thigh as the muscle tears.. Other additional symptoms such as swelling, bruising and muscle weakness may be noticed.

Hamstring strain is diagnosed by physical examination and history. Some of the diagnostic tests such as X-ray and MRI scan may be required by the doctor to confirm the condition.

Treatment

Immediately following an injury and before being evaluated by a doctor, you should initiate the R.I.C.E. method of treatment.

  • Rest: Rest from the activity which caused the muscle strain. Crutches may be recommended to avoid putting weight on your legs
  • Ice: Ice packs applied to the injured area will help to control swelling and reduce pain. Ice should be applied over a towel to the affected area for 15-20 minutes four times a day for several days. Never place ice directly over the skin
  • Compression: An elastic wrap or compression stocking applied to the injured area help to minimize the swelling
  • Elevation: Elevating the knee above heart level will also help to reduce swelling

Your doctor may prescribe nonsteroidal anti-inflammatory drugs to reduce pain and inflammation. Once the pain has subsided your doctor may recommend physical therapy which involves range of motion exercises that include gentle stretching and strengthening exercises to regain strength which will help to speed up the recovery. These exercises should be carried out regularly as it helps to regain the flexibility and improve the restricted motion.

Surgery is performed for hamstring strain only if the hamstring muscle is completely ruptured.
