Arthroscopic surgical approach and intra-articular anatomy of the equine suprapatellar pouch.
Abstract: To describe a direct arthroscopic approach to the suprapatellar pouch (SPP), its intra-articular anatomy, and report our clinical experience with SPP arthroscopy. Methods: (1) Experimental study and (2) retrospective clinical study. Methods: (1) Cadaveric equine hind limbs (n=24; 14 horses) and (2) 5 horses. Methods: Four femoropatellar joints (FPJ) were dissected or injected with latex to document surface landmarks and topographic anatomy. (1) Arthroscopic exploration of 20 SPP (10 equine cadavers) was performed and described, followed by dissection. (2) Medical records of horses that had FPJ arthroscopy were reviewed for cases where SPP portals were required. Results: (1) The optimal arthroscopic portal was located approximately 10 cm lateral to the longitudinal patellar axis and 2 cm proximal to the patellar base in the intermuscular septum between the biceps femoris and vastus lateralis muscles. This approach allowed arthroscopic observation of the proximal aspect of the lateral and medial femoral trochlear ridges, the intertrochlear groove, the patellar base, and the synovial recess of the SPP. (2) Additional arthroscopic and instrument suprapatellar portals were used in 5 of 25 horses to complete lavage/debridement in osteochondritis dissecans (OCD) and septic arthritis. Conclusions: Suprapatellar arthroscopy improved arthroscopic observation of structures located proximally in the FPJ and facilitated surgical access to the SPP. Conclusions: SPP arthroscopy is a safe and complementary approach to traditional distal FPJ arthroscopy that could be helpful for inspection and removal of free fragments/debris/fibrin located in the SPP, for OCD lesions extending proximally, and fracture(s) involving the proximal aspect of the patella.

The research article details a study on arthroscopic surgery of the suprapatellar pouch (SPP) in horses. The study is aimed at describing the surgical approach, anatomy involved, and reporting the study’s clinical experience in this field.
Research Methodology
- The study was both experimental and clinical in nature, involving cadaveric equine hind limbs and live horses. The process was carried out in two methods – experimental study and retrospective clinical study.
- In the experimental study, four femoropatellar joints (FPJ) were dissected or injected with latex to record surface landmarks and understand the topographic anatomy.
- Furthermore, arthroscopic exploration of 20 SPP from 10 horse cadavers was performed and described, followed by dissection.
- In the clinical retrospective study, the medical records of horses that underwent FPJ arthroscopy were reviewed. Specifically, cases requiring the utilization of SPP portals were analyzed.
Results of the Study
- The research identified the optimal arthroscopic portal to conduct the surgery was about 10 cm lateral to the longitudinal patellar axis and 2 cm proximal to the patellar base, in the intermuscular septum between the biceps femoris and vastus lateralis muscles.
- This particular approach allowed for the arthroscopic observation of structures located proximally in the FPJ. It also facilitated surgical access to the SPP.
- Additional SPP arthroscopic and instrument suprapatellar portals were used in 5 of 25 horses to complete lavage/debridement in conditions like Osteochondritis Dissecans (OCD) and Septic Arthritis.
Conclusions of the Study
- Suprapatellar arthroscopy provided an improved arthroscopic observation of structures located proximally in the FPJ and eased surgical access to the SPP.
- SPP arthroscopy was deemed a safe and complementary approach to traditional distal FPJ arthroscopy. It was found useful in inspection and removal of free debris and fibrin located in the SPP, for OCD lesions extending proximally, and fracture(s) involving the proximal aspect of the patella.
