ABSTRACT
OBJECTIVE@#To observe the clinical efficacy of intercondylar fossa plasty in preventing intercondylar fossa impingement syndrome after high tibial osteotomy.@*METHODS@#From August 2018 to August 2020, 84 patients with inverted knee osteoarthritis were treated by arthroscopy combined with high tibial osteotomy, and were divided into two groups with 42 cases in each group according to different surgical methods. In the intercondylar fossa plasty group, there were 13 males and 29 females, age ranged from 52 to 67 years old with an average of(58.27±4.32) years old, and arthroscopic intercondylar fossa plasty was performed first, and then high tibial osteotomy. In the arthroscopic cleansing group, 16 males and 26 females, age ranged from 50 to 71 years old with an average of (59.02±5.14) years old, underwent arthroscopic cleansing and then high tibial osteotomy. Postoperative treatment was evaluated using visual analogue scale(VAS), hospital for special surgery (HSS) score for the knee, and the occurrence of intercondylar percussa impingement.@*RESULTS@#All 84 patients were followed up, the duration ranged from 12 to 18 months with an average of (14.1±1.6) months. The VAS and HSS score of knee joint at 6, 12 and 18 months after surgery were significantly improved compared with preoperative period, and there was no significant difference between the two groups (P>0.05), but the incidence of intercondylar fossa index and intercondylar fossa impact between the two groups was significantly compared 18 months after surgery (P<0.05).@*CONCLUSION@#Intercondylar fossa plasty can effectively prevent the incidence of intercondylar fossa impact after high tibial osteotomy, and has a more significant effect on postoperative knee pain and function improvement.

Objective To compare the effect and safety of arthroscopic debridement enmbined with intercondylar fossa angioplasty in the elder with knee osteoarthritis.Methods Six-eight elderly with knee osteoarthritis were selected from June 2012 to December 2014 in this hospital and they were averagely and randomly divided into group A and B.Patients in group A were given arthroscopic debridement,while in group B were given and arthroscopic debridement,intercondylar fossa angioplasty.The levels of VAS scores,Lysholm scores,WOMAC scores and joint range of motion were measured and compared between the two groups after 3 months,6 months and 12 months of operation.The adverse events of the two groups were supervised and compared as well.Results All elder in the two groups had apparently decreasing in VAS scores and WOMAC scores (P＜0.05) after operation.Compared with group A,patients in group B had lower levels of VAS scores and WOMAC scores(P＜0.05) at 12 months after operation.The level of Lysholm score was significantly increased in the two groups after treatment(P＜0.05),while group B had a higher level at 12 months after treatment than group A (P＜0.05).The joint range of motion in the two groups were improved after treatment(P＜0.05).The elder patients in group B had better joint range of motion than group A at 6 and 12 months after operation (P＜0.05).Early postoperative swelling in the joints was the adverse event after operation,but there was no statistically difference between two groups.Conclusion The combination of arthroscopic debridement and intercondylar fossa angioplasty is effective to release knee pain,increase the clinical efficacy and improve the knee function.
ABSTRACT
Determinaram-se os índices de largura da fossa intercondilar (FI), após transecção do ligamento cruzado cranial em nove cães adultos submetidos à estabilização articular com retalho de fáscia lata. Os joelhos foram alocados em dois grupos, sendo o joelho direito (GI) submetido à incisuroplastia troclear (ITR) e posterior estabilização articular, e o joelho esquerdo submetido somente à substituição ligamentar (GC). Cada grupo foi dividido em três subgrupos correspondentes aos momentos de eutanásia aos 30, 90 e 180 dias de pós-operatório. Os índices de largura da FI foram determinados, macroscópica e radiograficamente, pela mensuração da abertura cranial da FI nos terços cranial, médio e caudal, e indexados em relação à largura epicondilar. Observou-se aumento significativo dos índices macroscópicos e radiográficos nas articulações do GI, sendo estes estatisticamente diferentes daqueles das articulações de GC. Não foi observada estenose intercondilar nos joelhos de GC após a estabilização articular. Conclui-se que a estabilização articular com retalho de fáscia lata preveniu a estenose da fossa intercondilar, e que a ITR promoveu o alargamento permanente dessa estrutura.
Intercondylar fossa width indexes (IFWI) were determined in nine adult dogs submitted to intercondylar notchplasty (IN) after transection of the cranial cruciate ligament (CCL) followed by a fascial strip stabilization. The right stifle was submitted to IN followed by fascial strip reconstruction of the CCL (GI) while in the left stifle IN was not performed (GC). Each group was then divided into three subgroups which corresponded to time of euthanasia at 30, 90 and 180 days after surgery. IFWI were determined, both macroscopically and radiographically, by measuring the cranial outlet of the intercondylar fossa in relation to the epicondylar width. A significant increase was observed in indexes of GI following IN, and these differed from indexes of GC throughout the evaluation period. It was concluded that articular repair using a fascia strip prevented stenosis of the intercondylar fossa, and that IN caused a permanent widening of it.
