Medial Collateral Ligament Sprain

The collateral ligaments are located on the sides of the knees. The medial collateral ligament (MCL) is located in the knee, connecting the inner side of the thigh bone to the shin (tibia) bone. The MCL helps the knee to resist force and keeps it stable against unusual movement. The collateral ligaments also control the sideways motion of the knee. This ligament may become torn or damaged as a result of direct impact to the outside of the knee. An injury may cause the MCL to loosen, stretch and possibly tear, resulting in pain and inflammation.

Symptoms of an MCL Sprain

Patients with an MCL sprain may experience the following symptoms on the inside of the knee:

  • Pain with flexion and extension
  • Tenderness along the inner part of the knee
  • Swelling
  • Loss of motion of the knee

After an MCL sprain, individuals may also experience, instability, or the feeling that the knee is going to give way.

Types of MCL Sprains

An MCL sprain is diagnosed through a physical examination of the knee. Additional imaging tests may include an X-ray or MRI scan. The doctor determines the grade of the MCL sprain based on the extent of damage, which may range from a mild tear to a complete rupture. MCL sprains may be classified as:

  • Grade 1 sprains occur when the ligament is mildly damaged
  • Grade 2 sprains occur when the ligament has been stretched and loosened
  • Grade 3 sprains occur when the ligament is completely torn

Grade 2 sprains are commonly referred to as a partial tear of the ligament.

Treatment of an MCL Sprain

Treatment for an MCL sprain varies based on the severity of the injury, but it can normally be treated with conservative methods that include:

  • Rest
  • Ice
  • Compression
  • Elevation
  • Knee brace

A physical therapy program may help to strengthen and restore function to the knee. In severe cases, when the ligament has torn completely and not healed properly, surgery may be necessary for repair.

Rotator Cuff Injuries

Four muscles in the shoulder that when injured or damaged can lead to sleepless nights, pain, and weakness.

The most common ways of injury to the rotator cuff are trauma, such as a fall on the outstretched hand, repetitive overload to the tendon by activity, or bone spurs cutting into the tendon.

Symptoms commonly begin with pain over the upper arm that is worse with reaching overhead, lying on your side, reaching behind your back, and weakness.

The rotator cuff has a very limited capacity to heal on its own and therefore treatment is often required to improve symptoms. This usually begins with a short period of rest, followed by a rehabilitation program focused on mobility, and strength to improve function. Steroid injection can be used if significant inflammation is present and interferes with the ability to engage in the exercise program. Two thirds of patients will improve with these modalities alone, and thus this is the first phase of treatment.

If symptoms persist, MRI is utilized to evaluate the rotator cuff for tears. Most commonly injured is the supraspinatus tendon. This is the muscle that allows you to put on a jacket, reach into the kitchen cabinet and get out the dishes, put a gallon of milk in the refrigerator, or pour a pot of coffee. Because the tendon is spring loaded, full tears commonly separate or retract. The more the retraction, the more serious the tear. If these tears are not addressed, atrophy will ensue and the tears will frequently get larger over time.

Surgical repair is performed arthroscopically and consists of stretching the tendon back out to it’s attachment point and repairing it back to the humerus greater tuberosity that it pulled off from. Traditionally, the shoulder was immobilized in a sling for up to 6 weeks before starting physical therapy to protect the repair. The downside of this approach was a high rate of postop stiffness, called frozen shoulder. We pioneered an accelerated rehab program for rotator cuff 25 years ago that reduced this immobilization down to just 5 days and actually lowered to postop stiffness rate.

Quality of the rotator cuff tissue has been a major determinant of success of the surgery, as well as the recurrent tear rate. The larger the tear and degree of separation, the higher the recurrent tear rate – that can approach 50 percent!

Innovation in rotator cuff surgery revolves around the use of biologics to reduce the risk of recurrent tears. CuffMend is an acellular, dermal allograft that is placed upon the repair to effectively double the thickness of an atrophic tendon and reduce the risk of recurrent tears. We have been effectively utilizing this technology over the past 2 years with great success to enhance patient outcomes for the most serious tears.

We remain committed to utilizing the best technology to remain innovators in rotator cuff surgery.
