Introduction: Conservative management is advisable for acute primary traumatic patella dislocation (PTPD). Surgical treatment reserved osteochondral fractures (OCF), medial patello femoral ligament (MPFL) avulsion/tear, compound injuries, and any underlying bony abnormalities requiring correction. MPFL repair (at avulsed site) or reconstruction along with correction in PTPD controversial. The purpose of this study to evaluate stability after fixation OCF without performing reconstruction, even the presence abnormalities. Material Methods: This a retrospective eight patients who had injury presented between 2016 2019. Pre-operative X-rays MRI were done assess status MPFL, identify calculate Insall-Salvati index, Tibial Tuberosity-Trochlear groove distance Trochlear dysplasia. All underwent surgery by open approach bioabsorbable pins suture material. was neither repaired at site nor reconstructed no corrections done. Results: Average size fragments 15*7 mm all involving facet patella. Lysholm score improved significantly from 32.8 94.8 Kujala 49.1 96 end 6 months. None patient instability till latest follow-up, average follow-up period 4.5 years (3–6 years). Clinically, apprehension test negative cases full ROM. Post-operative imaging including X-ray showed complete healing healing/regeneration same pre-existing if present preoperatively. Conclusion: shows excellent knee function union abnormality. Hence, OCF, there need repair/reconstruct correct pathology, only required.
