Orthopedic Vet Veterinary Orthopedic PGR Instrument Set

Professional Veterinary Orthopedic Implant & Instrument System
The PGR Patellar Groove Replacement Set is a premium veterinary orthopedic solution designed to address severe patellofemoral instability, trochlear dysplasia, end‑stage osteoarthritis, and failed revision surgeries in dogs and cats. Engineered with anatomical precision, biocompatible materials, and low‑friction bearing surfaces, this system restores normal patellar tracking, eliminates luxation, reduces pain, and supports long‑term stifle joint function for small animals.Professional Veterinary Orthopedic Implant & Instrument System

This complete surgical set includes anatomical PGR implants, porous base plates, specialized surgical instruments, and trial fitting components to enable accurate, reproducible implantation.
Materials: Surgical‑grade titanium alloy (Ti‑6Al‑4V ELI) / high‑strength medical stainless steel; articular surface with ADLC (Amorphous Diamond‑Like Carbon) coating
Sizes: Full range #1–#10 to fit toy breeds, small/medium breeds, large/giant breeds, and felines
Structure: Two‑piece design (porous base plate + articular groove prosthesis) for stable fixation and optimal bone ingrowth
Sterilization: Compatible with steam autoclave (134°C)
Core Functions
Reconstruct Damaged Trochlear Groove
Replaces shallow, deformed, worn, or arthritic femoral trochlear grooves with a stable, deep anatomical track to prevent patellar luxation.
Low‑Friction Articular Surface
ADLC coating delivers ultra‑low friction (μ≈0.05) to minimize wear, heat generation, and cartilage damage, restoring smooth patellar gliding.
Immediate & Long‑Lasting Stability
Porous base plate promotes rapid osseointegration for secure biological fixation, reducing implant loosening risk.
Correct Severe Instability
Ideal for cases where trochleoplasty, sulcoplasty, or soft‑tissue repair alone cannot achieve sufficient stability.
Revision Surgery Compatibility
Effectively addresses failed previous patellar stabilization procedures and post‑surgical complications.

Indications

Grade III–IV medial or lateral patellar luxation in dogs and cats
Severe congenital trochlear dysplasia (shallow, flattened, or absent groove)
End‑stage patellofemoral osteoarthritis with cartilage loss
Failed prior patellar surgery (revision cases)
Large/giant breed dogs with insufficient stability from conventional techniques
Post‑traumatic trochlear groove deformity or bone defectGrade III–IV medial or lateral patellar luxation in dogs and cats
Severe congenital trochlear dysplasia (shallow, flattened, or absent groove)
End‑stage patellofemoral osteoarthritis with cartilage loss
Failed prior patellar surgery (revision cases)
Large/giant breed dogs with insufficient stability from conventional techniques
Post‑traumatic trochlear groove deformity or bone defect

1. Patient Preparation & Anesthesia
Administer general anesthesia, position the patient in lateral recumbency, prepare and drape the affected stifle joint aseptically.
2. Surgical Exposure
Make a craniolateral parapatellar incision, elevate soft tissues, open the joint capsule, and expose the distal femur and patella. Inspect cruciate ligaments, menisci, and articular surfaces for concurrent injuries.
3. Bone Bed Preparation
Resect the damaged trochlear groove to create a flat, clean bone surface. Use specialized instruments to contour the distal femur for accurate base plate fitting.
4. Trial Implantation
Select appropriate‑sized base plate and PGR prosthesis using trial components. Verify fit, patellar tracking, and joint range of motion.
5. Implant Fixation
Secure the porous base plate to the femur with locking or cortical screws. Attach the articular PGR prosthesis firmly onto the base plate.
6. Alignment & Stability Adjustment
Perform supplementary procedures as needed:
Tibial tuberosity transposition (TTT)
Medial/lateral retinacular imbrication and release
Joint capsule repair
Confirm full‑range knee motion with stable, centered patellar tracking.
7. Irrigation & Closure
Copious lavage of the joint cavity. Layer closure of joint capsule, fascia, subcutaneous tissue, and skin. Apply sterile dressing.
Intraoperative Notes
Protect neurovascular structures and cruciate ligaments during exposure.
Use constant sterile saline irrigation to reduce thermal necrosis from bone reaming/sawing.
Ensure precise implant alignment to avoid abnormal tracking or impingement.
Confirm rigid screw fixation; avoid intra‑articular screw penetration.
Test stability through full flexion–extension before closure.
Postoperative Care & Precautions
Restricted Activity
Strict cage rest and controlled leash walking only for 8–12 weeks. Prohibit running, jumping, climbing stairs, and free roaming.
Pain Management & Medication
Administer antibiotics, analgesics, anti‑inflammatories, and joint supplements (glucosamine, chondroitin) as directed.
Wound Care
Keep the incision clean and dry. Use an Elizabethan collar to prevent licking/chewing. Suture removal at 10–14 days.
Rehabilitation
Gradual passive range‑of‑motion (PROM) exercises to maintain joint mobility. Physiotherapy may improve muscle strength and recovery.
Follow‑up Examinations
Postoperative radiographs at 2, 6, and 12 weeks to evaluate bone ingrowth, implant position, and healing progress.
Activity Resumption
Return to normal activity only after radiographic confirmation of complete bone integration and veterinary clearance.1. Patient Preparation & Anesthesia
