DOES PROXIMAL TIBIOFIBULAR JOINT MEDIATED PAIN MAKE PATIENTS UNHAPPY AFTER TOTAL KNEE ARTHROPLASTY IN KNEES WITH PRIMARY OSTEOARTHRITIS AND VARUS MALALIGNMENT?

Öz

OBJECTIVE: Presence of a clinical correlation has not been demonstrated between tibiofemoral joint (TFJ) and proximal tibiofibular joint (PTFJ) in knees with severe osteoarthritis. The purpose of this retrospective study is to clinically evaluate PTFJ in patients with total knee arthroplasty (TKA) performed for end-stage primary osteoarthritis with genu varum deformity.

MATERIALS AND METHODS: Patients with TKA performed for severe osteoarthritis with genu varum deformity were retrospectively evaluated. Relationships between PTFJ clinical examination findings and PTFJ type, hamstring tightness, and lateral joint line (LJL) tenderness were investigated using the chi-square test. Also, descriptive statistics were used.

RESULTS: Fifty-four patients (five male and 49 female; mean age 62.7 years; range 46-81 years) constituted the study group. Both knees were operated in 30 (55.6%) patients. Average follow-up period was 21.6 months (range 12-49 months). PTFJ tenderness, hamstring tightness, and LJL tenderness were established in six (7.1%), four (4.8%), and six (7.1%) knees, respectively. There were six (7.1%) knees with horizontal type PTFJ and 78 (92.9%) knees with oblique type PTFJ. PTFJ tenderness was determined in knees with oblique type PTFJ (chi-square test, p=0.000), knees with LJL tenderness (chi-square test, p=0.000), and knees with hamstring tightness (chi-square test, p=0.000).

CONCLUSIONS: PTFJ does not seem to be the exact source of lateral knee pain after TKA operations in knees with severe degenerative joint disease and varus malalignment. However, it should be considered that oblique-type PTFJ may have the potential to create pain in these knees

VARUS DİZİLİM BOZUKLUĞU VE PRİMER OSTEOARTROZLU DİZLERDE TOTAL DİZ PROTEZİ SONRASI PROKSİMAL TİBİOFİBULAR KAYNAKLI AĞRI HASTA MUTSUZLUĞUNA NEDEN Mİ?

AMAÇ: İleri evre gonartrozlarda proksimal tibiafibular eklem (PTFE) ile tibiofemoral eklem (TFE) arasındaki klinik ilişki daha önce gösterilmemiştir. Bu retrospektif çalışmanın amacı son evre gonartrozu olup diz protezi uygulanan genu varum deformiteli hastalarda PTFE’in klinik değerlendirmesidir.

GEREÇ VE YÖNTEM: İleri evre osteoartrozu olup diz protezi uygulanan genu varum deformiteli hastalar değerlendirmeye alındı. PTFE’in klinik muayene bulguları ile PTFE tipi, hamstring gerginliği, ve lateral eklem aralığı (LEA) hassasiyeti arasındaki ilişki ki-kare testi kullanılarak araştırıldı. Ayrıca tanımlayıcı istatistikte kullanıldı.

BULGULAR: Çalışma grubu (5 erkek ve 49 kadın; ortalama yaş 62.7 yıl; 46-81 arasında) elli dört hastadan oluş- maktadır. 30 hastanın (%55.6) her iki dizi ameliyat edildi. Ortalama takip süresi 21.6 ay (12-49 ay). PTFE hassasiyeti, hamstring gerginliği ve LEA hassasiyeti sırasıyla altı (%7.1), dört (%4.8), ve altı (%7.1) dizde tespit edildi. Altı dizde (%7.1) horizontal tip PTFE varken, yetmiş sekiz dizde (%92.9) oblik tip PTFE vardı. Oblik tip PTFE olan dizlerde PTFE hassasiyeti (ki-kare testi, p=0.000) , LEA hassasiyeti (ki-kare testi, p=0.000), hamstring gerginliği (ki-kare testi, p=0.000) tespit edildi.

SONUÇ: Varus dizilim kusuru olan ileri evre dejeneratif eklem hastalığı nedeniyle diz protezi yapılan hastalarda, PTFE’in ameliyat sonrası lateral diz ağrısının kaynağı olmadığı ortaya konmuştur. Bununla birlikte oblik tip PTFE bu dizlerde potansiyel ağrı kaynağı olabileceği düşünülebilir
