Minimally Invasive Surgery Gaining Popularity
Arthroscopic knee surgery is one of the most commonly performed orthopedic procedures. For decades, surgeons have typically used a three-portal technique during arthroscopy that requires three separate incisions. However, a newer minimally invasive surgical approach known as unilateral biportal endoscopy is gaining popularity among surgeons and patients. This technique uses only two small incisions rather than the traditional three incisions.
Benefits of Fewer Incisions
The main benefit of the Unilateral Biportal Endoscopy technique is that it reduces the number of incisions needed from three down to two. This means less tissue damage, less postoperative pain, and quicker healing time for patients. Surgeons also appreciate how the two-incision method provides better visualization of the knee joint compared to traditional three-portal arthroscopy. Making only two small puncture wounds rather than three incisions leads to improved cosmetic outcomes as well.
Easier Surgery and Shorter Recovery
By using just two entry points rather than three separate incisions, the unilateral biportal method fundamentally changes how surgeons are able to access and repair structures inside the knee joint. With fewer portals crowding the surgical field, surgeons have an easier time maneuvering arthroscopic instruments. This increases surgical efficiency and precision. The reduced trauma from two smaller incisions versus three larger incisions allows patients to bear weight on the affected knee sooner. Physical therapy can begin earlier in the recovery process.
Long-Term Benefits
While short-term advantages like less pain and rapid healing time are clear, long-term benefits of unilateral biportal knee arthroscopy are gaining recognition as well. Less irritation and damage to surrounding soft tissues means a lower risk of postoperative stiffness, adhesive capsulitis, and arthrofibrosis formation over months and years following surgery. Early studies also indicate a very low failure rate when surgeons use this minimally invasive two-portal approach compared to traditional three-portal knee arthroscopy techniques.
Improving Surgical Techniques
As with any new surgical method, the learning curve can be steep for surgeons accustomed to traditional multi-portal techniques. Proper training in anatomical landmarks and fluid management is important when transitioning to unilateral biportal endoscopy. Some advanced procedures like ACL reconstruction remain more technically demanding using just two incisions versus three portals. However, for many common knee arthroscopy procedures like meniscal repair, removal of plica or loose bodies, and debridement, the two-incision method has distinct advantages. Over time, modifications to instruments and fluid-management systems are helping address some of the initial limitations of the unilateral approach.
Widespread Adoption
Faster recovery, fewer long-term issues, and improved outcomes have caused the unilateral biportal technique to gain notable popularity among orthopedic surgeons worldwide in a relatively short time period. What was once an unfamiliar alternative to the standard three-portal method is now being designated as the preferred technique at leading hospitals and ambulatory surgery centers. While traditional multi-portal arthroscopy will remain appropriate for certain complex cases, simple and intermediate scope procedures are increasingly transitioning to the minimally invasive two-incision method. Both patients and insurers appreciate how unilateral biportal endoscopy translates to substantial savings through earlier return to normal activity and work. As training focuses on this approach, it is poised to become the new standard for most knee arthroscopy procedures.
In the unilateral biportal endoscopic technique represents an excellent example of how minimally invasive surgical innovations can simultaneously benefit patients, physicians, and the healthcare system overall. By reducing trauma and expediting recovery compared to traditional multi-portal arthroscopy, this two-incision method improves outcomes while lowering costs. With further refinement and more widespread dissemination of proper training methods, the unilateral approach promises to reshape how common knee procedures are performed.
