Many middle-aged and older adults suffer from shoulder pain and limited shoulder range of motion, and often have multiple visits to the doctor without satisfactory results. The cause of shoulder pain and limited range of motion is often referred to as “frozen shoulder” or “50 shoulder”. In the past, some patients were afraid to move their shoulders because of the pain, which eventually led to severe shoulder stiffness, while others endured severe pain and had to move their shoulders strongly, which made the recovery process painful and easily led to secondary shoulder injuries. In fact, “frozen shoulder” or “50 shoulder” is not an exact diagnosis, as there are many shoulder diseases that can manifest as shoulder pain and limited range of motion. Only when the cause of the symptoms is found can the correct treatment be administered. Most patients can be cured with standard non-surgical treatments such as medication, physical therapy and appropriate functional exercises. In the minority of cases where non-surgical treatment does not work, minimally invasive shoulder arthroscopy can also be used to obtain a good functional recovery. ”Tennis elbow, scientifically known as “humeral epicondylitis,” is a common cause of elbow pain. Patients often experience pain in the lateral aspect of the elbow joint, with weakness in lifting and increased pain. Many patients endure the pain for a long time, and some have undergone several closures without significant improvement. “Tennis elbow is a degenerative disease and is not difficult to diagnose, but it is important to choose the appropriate treatment for each patient. 80% or more of tennis elbow cases can be completely cured by standard non-surgical treatments such as medication, braces, physical therapy and appropriate rehabilitation exercises. For those who are not effective in non-surgical treatment, surgical treatment can be considered, which is minimally invasive and has stable and reliable results.
