“…This technique has recently been reported as a salvage procedure in conditions of severe OA of the trochlear groove due to patella luxation. There are few studies on the use of PGR, and no reports on custom-made PGR are available in the literature [55,56]. In a retrospective case series study, thirty-five dogs with patellar luxation in association with extreme patellofemoral OA had their femoral trochlear groove replaced with a PGR prosthesis (KYON AG, Zurich, Switzerland).…”

The successful clinical application of bone tissue engineering requires customized implants based on the receiver’s bone anatomy and defect characteristics. Three-dimensional (3D) printing in small animal orthopedics has recently emerged as a valuable approach in fabricating individualized implants for receiver-specific needs. In veterinary medicine, because of the wide range of dimensions and anatomical variances, receiver-specific diagnosis and therapy are even more critical. The ability to generate 3D anatomical models and customize orthopedic instruments, implants, and scaffolds are advantages of 3D printing in small animal orthopedics. Furthermore, this technology provides veterinary medicine with a powerful tool that improves performance, precision, and cost-effectiveness. Nonetheless, the individualized 3D-printed implants have benefited several complex orthopedic procedures in small animals, including joint replacement surgeries, critical size bone defects, tibial tuberosity advancement, patellar groove replacement, limb-sparing surgeries, and other complex orthopedic procedures. The main purpose of this review is to discuss the application of 3D printing in small animal orthopedics based on already published papers as well as the techniques and materials used to fabricate 3D-printed objects. Finally, the advantages, current limitations, and future directions of 3D printing in small animal orthopedics have been addressed.

“…4 Complications associated with PGR in dogs include prosthesis dislodgment, reoccurrence of patellar luxation, progression of the osteoarthritis, slippage of patella over the distal end of the prosthesis, inappropriate implant selection, and capsular thickening. 10,19 Although postoperative radiographs revealed thickening of the patella tendon, physical examination revealed no clinical signs associated with this. Further research incorporating a larger number of patients would be required to evaluate frequency and clinical significance of this finding.…”

The aim of this study was to report patellar groove replacement in a 6-year-old domestic short hair cat with chronic unilateral pelvic limb lameness and severe femoro-patellar osteoarthritis due to medial patellar luxation. This study is a case report. Computed tomographic scan of the affected limb revealed marked periarticular osteophytosis, medial trochlear ridge erosion, marked flattening of femoral trochlea, ectopic pseudo-trochlear groove, and medial patellar luxation. Femoral trochlear ostectomy with patellar groove replacement, release of the medial fibrocartilage, partial parasagittal patellectomy, and lateral tibial tuberosity were performed. Clinical review and radiographs performed 53 days post-surgery revealed no complications and substantial decrease in lameness. Thirteen months postoperatively the cat scored 2/72 on the Feline Musculoskeletal Pain Index questionnaire by the owner, indicating good mobility, minimal discomfort, and good quality of life. As far as the authors are aware, this is the first report of the use of patellar groove replacement in the management of feline medial patellar luxation. Patellar groove replacement, in combination with adjunctive procedures, resulted in a substantial improvement in lameness in this cat with chronic medial patellar luxation and severe femoro-patellar osteoarthritis.

“…Traditional techniques for bone reconstructions include tracheoplasty and tibial tuberosity transposition (Bosio et al, 2017;DeCamp, 2015;Von Pfeil & DeCamp, 2009;Wangdee et al, 2013). PGR is a new procedure already reported successfully for treating severe osteoarthritis (Dokic et al, 2015) and iatrogenic trochlear damage secondary to tracheoplasty (Kim et al, 2016); thus, the prosthesis was chosen as a result of the significant hypoplasia of the medial trochlear ridge present in the patient in question.…”

“…The most commonly employed treatments for MPL correction include tracheoplasty, tibial tuberosity transposition, imbrication of the lateral retinaculum (DeCamp, 2015;Von Pfeil & DeCamp, 2009), and trochlear sulcus replacement with prosthesis (Patellar Groove Replacement -PGR), the latter recently reported also for the treatment of severe osteoarthritis (Dokic et al, 2015) and iatrogenic trochlear injury (Kim et al, 2016).…”

Medial patella luxation is a condition resulting from congenital bone deformities that in the long term may result in rupture of the cranial cruciate ligament. These orthopedic ailments are responsible for much of the pelvic limb claudication in dogs and degenerative joint disease. Claudication and joint pain are the main clinical manifestations, and the diagnosis is confirmed by orthopedic examination for both conditions. The simultaneous treatment of these diseases is a challenge for the surgeon. This study reports on the association of trochlear sulcus replacement with prosthesis with modified plateau leveling osteotomy for simultaneous treatment of grade III medial patellar dislocation and cranial cruciate ligament rupture in dogs.
