Objective To explore the clinical efficacy of arthroscopy for habitual patellar dislocation(HPD)in children.Methods From July 2015 to July 2021,retrospective review was conducted for 20 HPD children.There were 8 boys and 12 girls with an age range of(5.8-15)year.According to different surgical approaches,they were assigned into two groups of arthroscopy(n=9 with 10 knees)and open(n=11 with 12 knees).Lateral release,medial contraction and patellar ligament semitendinous transfer were performed.Two groups were compared in terms of basic clinical profiles,imaging examinations and Lysholm score of knee.Re-suits During an average follow-up period of 24(18-36)month,there was no wound infection or other compli-cations.Redislocation(n=1)occurred in open group.Two groups were similar in basic profiles(P＞0.05).Operative duration of arthroscopy and open groups was[95.5(94.3,97.8)vs.99.0(95.0,111.3)min],blood loss[(23.00±5.89)vs.(50.83±8.21)ml],incision length[(6.60±0.70)vs.(13.50±2.39)cm],length of hospital stay[7.0(7.0,9.0)vs.9.0(7.0,10.0)day],time to full weight bearing[(8.70± 0.95)vs.(10.58±2.02)week],normal knee activity[(65.50±6.43)vs.(75.83.00±11.25)day]and postoperative Lysholm score of knee[95.00(92.75,95.25)vs.90.00(86.25,94.25)].And there were sig-nificant inter-group statistical differences(P＜0.05).No significant difference existed in patellofemoral fitting angle[(-8.2±1.75)vs.(-8.5±2.32)degree]or lateral patellofemoral angle[(6.80±1.87)vs.(7.17 ±1.64)degree].Conclusions For HPD,arthroscopic lateral release,medial contraction and patellar liga-ment semitendinous transfer is superior to traditional incision.It offers a smaller incision,shorter operative dura-tion,minimal intraoperative hemorrhage,shorter hospitalization stay and faster recovery of knee function.There is no redislocation.
