Abstract
Objective:To investigate the short-term clinical efficacy and surgical techniques of minimally invasive unicondylar knee arthroplasty in the treatment of knee osteoarthritis.Method:18 cases of severe lesions in the medial compartment of the knee joint osteoarthritis in our department were retrospective analyzed from April 2014 to March 2016.All patients were given minimally invasive unicondylar knee arthroplasty,the operation time, intraoperative blood loss,preoperative and postoperative hemoglobin levels,postoperative incision infection, knee joint prosthesis loosening,sinking,periprosthetic fracture,anterior knee pain,knee flexion and varus deformity correction were recorded.The function of knee joint was evaluated by HSS knee function score before and after operation.Result:All patients were followed up for 6-23 months,average 14.6 months.Medial knee pain relief,in addition to 1 case joint infection occurred,no cases of prosthesis loosening, sinking,periprosthetic fracture and anterior knee joint pain happen.Preoperative knee flexion angle of 100°-110°,postoperative of 120°-135°;preoperative varus angle of 0°-9° and postoperative was 0°-3°;preoperative HSS score were 70 points, postoperative were 93 points,good rate of 94%.The operative time was 60-100 min,average(82.00±5.62)min, intraoperative blood loss was 80-260 mL,average (150.00±40.67)mL,preoperative hemoglobin was 115-132 g/L,mean 124.3 g/L,postoperative was 106-127 g/L,average 118.2 g/L.Before and after operation, the patients of observation indexes were compared with each other,the differences were statistically significant (P<0.05).Conclusion:Minimally invasive knee unicondylar arthroplasty for knee joint medial compartment osteoarthritis patients with small surgical trauma,short operation time,less bleeding, postoperative recessive less blood loss,flexion contracture and deformity correction retained bone mass,less complication in strictly controlled use of indication,it is a good choice.关键词
