What is arthroscopy?

Arthroscopy inserts a thin tube that has a subminiature camera and laser surgery equipment inside into the shoulder joint, knee joint, or ankle joint. It can diagnose and treat the damaged areas within the joint. The benefits are that medical professionals can directly check the status of the joint through the monitor and can make accurate diagnoses and treatments.



Benefits of arthroscopy surgery
  • 1. It causes minimal pain and the scars are hard to notice.
  • 2. It can make accurate diagnoses that cannot be made even with specialized imaging like CT or MRI.
  • 3. It has a very low possibility to develop a complication.
  • 4. Recovery is fast.
Arthroscopy applicable diseases

These diseases can be treated by arthroscopy.

1Knee Joint
1) Meniscal tear

The meniscus, which works as a buffer between the femur and the tibia, can be divided into the medial meniscus and the lateral meniscus. Meniscal tear is often associated with other knee injuries, like the distortion of the knee during physical activity and anterior cruciate ligament rupture. In elderly patients, there are cases where this happens without an external injury because of the weakening of the cartilage, and this is called a degenerative meniscal tear.

2) Cruciate ligament tear

The cruciate ligament includes the anterior cruciate ligament and the posterior cruciate ligament. Out of these, the anterior cruciate ligament tear is the most common knee injury. Approximately half of these injuries occur with other areas of the knee (meniscus and medial collateral ligament (MCL)). Major causes include the sudden change of direction, stopping motions, incorrect landing motions, and direct contact motions like tackling. Also, the tear of the posterior cruciate ligament, which connects the femur and tibia behind the knee, is both uncommon and hard to examine. This usually occurs when there was a direct impact to the front of the knee, when one misses one’s footing, and when the ligament was forcefully stretched beyond the limit.

3) Middle stage degenerative knee arthritis

Middle stage degenerative knee arthritis is right before the cartilage is completely worn down and gone. If it is left untreated, it will develop into a late stage and the pain will become worse. Therefore, it is needed to treat only the damaged areas through arthroscopy surgery and generate new bony tissue and cartilage.

4) Cartilage damage in the knee joint

Degenerative arthritis may occur when the bone cartilage protecting the knee bone is damaged.

5) Other

Includes synovitis, removal of the vitreous body in the joint, and osteochrondritis dissecans.

2Shoulder Joint
1) Rotator cuff tear

The "rotator cuff" indicates the four muscles that wrap around the shoulder bone (supraspinatus, subscapularis, infraspinatus, and musculus teres minor) among the muscles lifting the shoulder. Rotator cuff tears usually appear among patients over 40 years old and major causes are low blood circulation and the collision of bone and tendon. It may also cause frozen shoulders. Please be aware that rotator cuff tears are hard to be cured naturally and, when neglected, it may get worse because the torn tendon curls inward.

2) Impingement syndrome

The causes of impingement syndrome include the congenital deformity of the acromioclavicular joint and coronoid process, weakened rotator cuff, and calcification. People with occupations requiring to use their shoulders repeatedly suffer from this disease often and may feel pain when raising the arm above the head, or while scratching their back.

3) Frozen shoulders

It is the most common cause of shoulder pain and it is also called 'Osipgyeon' because it tends to appear before and after the age of 50. Frozen shoulders usually occur in the tissue called an articular capsule, surrounding the deepest area of the shoulder joint. It is also commonly associated with endocrine diseases like diabetes and thyroid diseases.

4) Habitual dislocation

Habitual dislocation is divided into front, back, and multi-directional depending on the direction it falls out. It also can be divided into traumatic and non-traumatic depending on the injury area. For front traumatic dislocation, you will feel like your arm is dislocated when you pose to throw a ball. If you feel like your arm is sagging down and it is associated with pain and anxiety when holding a heavy item, you should suspect a back dislocation.

3Foot Joint
1) Ankle cartilage damage

Ankle cartilage damage refers to the cartilage falling into the joint. This happens when the cartilage around the joint bone lacks blood circulation naturally or falls in due to an external injury. It may occur due to a circulation disorder without an external injury. Sometimes, it is caused because the ankle joint bones bump into each other.

2) Ankle ligament damage

Simply speaking, ankle ligament damage means a "sprained ankle". It is when the ligaments around the ankle are disconnected and it is also called "ankle sprain". Ankle ligament damage usually occurs when the outside edge of the foot hits the ground and is twisted after a jump, but also occurs when you take a wrong step while going downstairs.
