“…In the latest reports, the use of navigation, the different types of inserts (fixed-bearing / rotating platform) and the different surgical approaches (modified subvastus / medial parapatellar ) have no influence the flexion angle after total knee arthroplasty [7][8][9]. What is the factor that improves flexion angle after the total knee arthroplasty?…”

The Dual Bearing Knee (DBK) prosthesis is a new concept which has a mobile-bearing insert. In May 2001, the posterior femoral condyle design of the DBK was changed to become smaller and there was a posterior shift in the base of the insert dish (Hi-Flex). Between 1998 and 2004, 371 DBKs (112 Hi-Flex and 220 Standard) were performed by one surgical team. There was a significant difference in postoperative flexion angle between the Hi-Flex and Standard DBKs (117.0°and 111.3°; p=0.001). The delta flexion angle in the Hi-Flex (−2.4°) was significantly increased compared with that in the Standard DBK (−9.6°) (p=0.001). In the Hi-Flex DBK, the postoperative flexion angle (5.7°) and the delta flexion angle (7.2°) were significantly larger than for the Standard DBK (p<0.001). These results suggest that the flexion is greater for a design with smaller posterior condyle prosthesis and with a posterior shift in the base of the insert dish in CR mobilebearing TKA.

“…Similar improvements in pain score from 14.1 to 49.3 and 6.9 to 42.6 has been previously reported with TKA. 7,10 Average range of movement in our study preoperatively was 91.9 degrees of flexion which increased to 111.6 degrees postoperatively with an improvement of 20.5 degrees. Similar benefits in range of movements were obtained in most of the previous studies.…”

“…There were 15 (50%) female patients and 15 (50%) male patients in our study which is in contrast to most of the previous studies in which there was predominance of female patients (Table 1). [5][6][7][8][9][10][11] Our patients were younger than those in most of the previous studies except one. [5][6][7][8][9][10][11] Most of the indications for TKA in our study were due to osteoarthritis (37 knees) and rheumatoid arthritis (5 knees).…”

Background: The incidence of arthritis is rising in India due to increase in the proportion of ageing population and obesity. Cruciate retaining total knee arthroplasty (TKA) is a promising mode of treatment for end stage arthritis, with excellent functional outcome. Hence, we have evaluated the functional outcome of posterior cruciate ligament retaining TKA and the problems related to the procedure at our institute.Methods: This prospective study was conducted on 30 patients who underwent posterior cruciate ligament retaining primary TKA at a tertiary health care centre between December 2012 and May 2014. Patients were evaluated using Knee society score (knee score and function score) at regular follow up visits.Results: The study included TKA for 42 knees in 30 patients. Indications for TKA were osteoarthritis in 37 knees and rheumatoid arthritis in 5 knees. The average follow-up period was 24 weeks. All the 42 knees had poor knee score (<60) and poor functional score (<60) preoperatively. Postoperatively 37 knees had excellent (80-100) and 5 knees had good knee score (70-79) whereas 22 patients had excellent (80-100), 5 patients had good (70-79), 2 patients had fair (60-69) and 1 patient had poor functional score (<60). Conclusions: Our study demonstrates that posterior cruciate retaining TKA is a reliable procedure with excellent functional outcome, pain relief and early return of patients to their daily activities. Posterior cruciate retaining TKA provided excellent knee society score and functional score in majority of patients.

ÖzetAmaç: Bu çalışmada farklı markalarda total diz protezi uygulanmış hastaların ameliyat sonrası hareket açıklığının değerlendirilmesi ve çeşitlilik gösteren protez tiplerinden hangisi ya da hangilerinin en iyi sonucu verdiğinin tespit edilmesi amaçlandı. Gereç ve Yöntem: Nisan 2005 ile eylül 2007 yılları arasında gonartroz tanısı primer total diz artroplastisi uygulanan 225 hastadan takibi yapılan 180 tanesi (139 kadın, 41erkek. Ort. Yaş: 65 dağılım 51-82) ça-lışmaya alındı. Bütün hastalarda gonartroz nedeni primer osteoartrit idi. Sekonder osteoartriti olan hastalar çalışmaya alınmadı. Bütün hastalar aynı cerrahi teknik ile ameliyat edildi ve aynı rehabilitasyon protokolü uygulandı. Patella hiçbir hastada değiştirilmedi. Arka çapraz bağ olguların bir kısmın-da korundu bir kısmında kesildi. Hastalarda toplam 7 farklı protez 16 alt grup kullanıldı. Bütün ölçümler aynı cerrah tarafından yapıldı. Ortalama takip süre-si 31 ay (24-49ay) idi. Bulgular: Hastalar ameliyat öncesi ve sonrası hareket açıklıkları alt gruplara ayrılmadan ana ticari markalara göre değerlendirildi-ğinde, rotaglide® ve LCS® diz protezlerinde ameliyat sonrası hareket açıklı-ğında azalma gözlenirken, maxim ve kinemax protezlerde hareket açıklığı değişmemiş olup diğer incelenen markalarda hareket açıklığı artmıştır.İstatis-tiksel olarak nexgen ve scorpio protezlerde ameliyat sonrası fleksiyon derecesinde artış anlamlı olarak değerlendirilmiştir (p<0.001). Hastalar; protezin mekanik özelliklerine göre sınıflandırıldığında ise bağkesen protezler ve mobil protezlerde ameliyat sonrası hareket açıklığında anlamlı artış bulunmuş-tur (p<0.001).Hiperflex, fix ve bağ koruyan protezlerde ise hareket açıklığında anlamlı artış saptanmamıştır ( p>0.001). Tartışma: Sonuç olarak farklı protez tipleri arasında fleksiyon dereceleri farklı çıksada en yüksek değerlere sahip olan son üç protez ile en düşük değerlere sahip protezler arasında 10 o fark olduğu saptandı. Hareket açıklığındaki değişiklikler istatiksel olarak fark yaratsada alınan sonuçlar klinik olarak anlamsız görünmektedir. All patients underwent to primary total knee arthroplasty. Primary osteoartrhritis is the reason of gonarthrosis. The patients with secondary osteoartrhritis were excluded from the study. All the patients were operated by the same surgical team and rehabilitated after surgery. Patella didnt change any patient. PCL was protected in some of the patients and cut some of patients. Totally seven type prosthesis in 16 subgroup were applied to the patients. All measurement were done by the same surgeon. Average follow up period was 31 months (24-49 months). Results: Patients without subgrouping were tested according to the range of motion before and after surgery to the type of the prosthesis trademark. Range of motion was decreased with the usage of Rotaglide and LCS® type of prosthesis. Range of motion didnt change with the usage of Maxim and Kinemax type. The range of motion increased in the other trademark of prosthesis. Flexion angle was increased statistically significant with nexge...
