Why do patients need labral repairs? 
                    A shoulder labral tear is almost always the result of overly repetitive shoulder motion. Otherwise, it’s caused by a sudden trauma to the shoulder, such as a direct hit, an abrupt pull, or a fall. Lifting heavy objects can sometimes cause a labral tear, which is why weightlifters are susceptible to the injury. 
                                        Patients with labral tears are likely to experience instability in the shoulder, greatly decreased range of motion, a grinding or locking sensation in the shoulder, and significant pain. It may be difficult to move or use the arm at all with a labral tear in the shoulder.
                                        The most common reasons for labral repairs include:
                                        
                                                    - Cartilage injury from repetitive motion
- Shoulder injury due to sudden impact or other trauma
- Labral tear due to age
