The shoulder complex is comprised of four joints—glenohumeral, acromioclavicular, sternoclavicular, and scapulothoracic—that coordinate with one another so that we can perform numerous activities with our upper extremities. In addition to the aforementioned joints, there are several primary muscles that stabilize the shoulder and allow it to move in its three primary planes: front (anterior), back [..]

It’s estimated that nearly 800,000 knee replacements are currently performed in the United States each year. Due to the combination of ageing and poor lifestyle choices, researchers expect the number of annual total or partial knee arthroplasty procedures to triple by 2040.  While many patients report significant improvements in pain and function following a knee [..]

Among the roles the hip joints play in the human body, perhaps none is as important as the ability to perform everyday activities like standing, walking, and running. Of course, these actions involve multiple other body parts, so it’s no surprise that when a patient presents with hip pain, they often have additional issues. In [..]

Overuse injuries in baseball—particularly in the shoulder and elbow—are a significant problem at both amateur and professional levels. Studies have shown that shoulder pain is one of the most common complaints among amateur baseball players, with a prevalence ranging from 13.4% to 20.6% of players. Elbow injuries are also very common and affect from about [..]

The knee is a complex hinge type of joint that consists of bone, cartilage, tendons, and ligamentous structures that are vulnerable to injury during high-intensity rotational and explosive movements. As such, acute knee injuries are often associated with sporting activities. It’s estimated that 2.5 million acute knee injuries occur in the United States each year. [..]

The hamstrings consist of four muscles in the back of the thigh and upper leg—the biceps femoris (long and short heads), semitendinosus, and semimembranosus—that connect the ischial tuberosity to the knee area. This collection of muscles performs a variety of functions including bending or flexing the knee joint; extending the hip joint; internal hip rotation; [..]

Shoulder impingement syndrome (SIS) is a very common cause of shoulder pain that affects about half of adults at some point in life. Essentially, the condition describes the pinching of pain-sensitive structures in the shoulder that restricts normal use or function, with raising the shoulder being a very common activity that triggers a painful reaction.  [..]

Running is a popular recreational activity, and it’s an effective form of aerobic exercise for both young and old. It’s estimated that 50-60 million Americans regularly run or jog on tracks, city streets, or trails. However, running also carries a risk for injury. It’s estimated that at least half of recreational runners will sustain an [..]

Simply put, long-standing hip and groin pain (LHGP) is discomfort in the hip and groin region lasting six weeks or longer that often limits physical function and reduces quality of life.  For some patients, simple activities like walking, climbing stairs, and sitting for prolonged periods of time can feel impossible. Unfortunately, LHGP tends to come [..]

When a patient seeks care for shoulder pain, they usually point to the ball and socket glenohumeral joint as the source of their problem. However, a contributing cause of the patient’s shoulder pain and disability may actually be the scapula or shoulder blade and if scapular dyskinesis is present and untreated, the patient may not [..]
