Clinical outcomes of retrograde tibial plateau osteochondral autologous transplantation under arthroscopy for knee chondral injuries
Objective:To investigate the clinical effectiveness of retrograde tibial plateau osteochondral autologous transplantation surgery(OATS)under arthroscopy for knee chondral injuries.Methods:A retrospective analysis was conducted on the clinical data of 10 patients with knee tibial plateau chondral injuries treated with retrograde tibial plateau OATS under arthroscopy at the First Affiliated Hospital of Jinzhou Medical University from September 2017 to June 2022.The knee function of the patients was evaluated by the Lysholm score and the pain levels were assessed by the visual analogue scale(VAS).The preoperative and postoperative knee functions and pain levels were compared.Postoperative complications were recorded.Results:The patients were followed up for 12 to 28 months.At 3 months post-surgery,the Lysholm score significantly increased,and VAS score significantly decreased from preoperative levels(all P<0.05).At 6 months post-surgery,the Lysholm score was significantly higher than both preoperatively and 3 months postoperatively,with VAS score being lower than preoperative and 3 months postoperatively(all P<0.05).At 12 months post-surgery,the Lysholm score remained significantly higher than that at both pre-and 6 months post-surgery,with VAS scores significantly lower than that at both pre-and 6 months post-surgery(all P<0.05).No postoperative complications such as incisional or intra-articular infection,thrombosis,or graft extrusion were observed.Conclusions:Retrograde tibial plateau OATS under arthroscopy effectively alleviates pain and improves knee joint function in patients with knee chondral injuries,with favorable clinical outcomes,and is recommended for wider clinical application.
