He is an expert in arthroscopic (minimally invasive) shoulder surgery, but he will not recommend surgery unless all non-operative solutions have been explored and exhausted. The shoulder is an extremely fascinating joint with lots of moving parts. As such, injuries are common and often complex. Over the last few years, there have been dramatic improvements in the way shoulder pathology is treated. Orthopedic surgeons are now able to perform most shoulder surgeries using arthroscopic techniques (small incisions) that are at least as good, if not better than, the open (larger incisions) procedures of the past.He has trained with the world’s experts in minimally invasive shoulder surgery, so the care and technical expertise his patients receive is cutting-edge and based on the best available research for various shoulder ailments (rotator cuff tears, labral tears and instability, etc.). He is always actively looking for new ways to improve his surgicalonsurgical treatment methods to help his patients regain their active lifestyle.Dr. Koo feels it is unfortunate that surgeons are often not associated with empathy, because they are in the ideal position to support patients as they recover from difficult procedures.
