“…The literature search resulted in 5,290 hits for the survival review and 56 studies were included, with a total of 20.599 patients; see Figure 1 (Goldberg et al 1988, Laskin 1990, Samuelson et al 1990, Wright et al 1990, Moran et al 1991, Grewal et al 1992, Ranawat et al 1993, 1994, Rinonapoli et al 1994, Weir et al 1996, Knight et al 1997, Scott 1997, Ansari et al 1998, Hsu et al 1998, Ewald et al 1999, Mont et al 1999, Buehler et al 2000, Emerson et al 2000, Robertsson et al 2000, Stukenborg-Colsman et al 2000, Berger et al 2001a,b Faraj et al 2001, Gill et al 2001, Khaw et al 2001, Schroder et al 2001, Sextro et al 2001, Fetzer et al 2002, Forster et al 2002, Khaw et al 2002, Worland et al 2002, Mayman et al 2003, Goldberg et al 2004, Arora et al 2005, Bozic et al 2005, Campbell et al 2006, Clayton et al 2006, Gioe et al 2006, Lachiewicz et al 2006, Vessely et al 2006, Bertin 2007, Kim et al 2007, Rodricks et al 2007, Zaki et al 2007, Anderson et al 2008, Chana et al 2008, Dalury et al 2008, Parsch et al 2008, Ritter et al 2008, Santini et al 2008, Smith et al 2008).

Early migration of tibial components is associated with late revision

Purpose We performed two parallel systematic reviews and meta-analyses to determine the association between early migration of tibial components and late aseptic revision.Methods One review comprised early migration data from radiostereometric analysis (RSA) studies, while the other focused on revision rates for aseptic loosening from long-term survival studies. Thresholds for acceptable and unacceptable migration were determined according to that of several national joint registries: < 5% revision at 10 years.Results Following an elaborate literature search, 50 studies (involving 847 total knee prostheses (TKPs)) were included in the RSA review and 56 studies (20,599 TKPs) were included in the survival review. The results showed that for every mm increase in migration there was an 8% increase in revision rate, which remained after correction for age, sex, diagnosis, hospital type, continent, and study quality. Consequently, migration up to 0.5 mm was considered acceptable during the first postoperative year, while migration of 1.6 mm or more was unacceptable. TKPs with migration of between 0.5 and 1.6 mm were considered to be at risk of having revision rates higher than 5% at 10 years.Interpretation There was a clinically relevant association between early migration of TKPs and late revision for loosening. The proposed migration thresholds can be implemented in a phased, evidence-based introduction of new types of knee prostheses, since they allow early detection of high-risk TKPs while exposing only a small number of patients.

“…By contrast, TKA is only indicated in 12% of cases of posttraumatic osteoarthrosis (POA) in Germany [6]. In published retrospective studies, this percentage is between 0% and 6% [2,[7][8][9][10][11][12][13][14][15][16][17]. Changes in leisure activities undertaken by younger patients and the increasing popularity of sports that carry a high risk of injury have led to an increase in the incidence of POA [18,19].…”

European Journal of Trauma Ab stractBackground: The incidence of posttraumatic osteoarthrosis, especially in younger patients, increases. In different studies total knee arthroplasty (TKA) is only indicated in 0-12% of cases of posttraumatic osteoarthrosis, because most authors feel that the indication for TKA in younger patients should be narrowly restricted. The most common indications for TKA include primary idiopathic osteoarthrosis and rheumatoid arthritis predominantly in patients > 60 years. Patients and Methods: In this prospective study a total of 188 patients with 197 TKAs were compared. 92 patients (93 TKAs) had a posttraumatic osteoarthrosis, 96 patients (104 TKAs) a nontraumatic osteoarthrosis. All patients received the same modular tricompartmental TKA in uncemented technique regarding femoral and tibial component. The patella was always cemented. All operations were performed by a group of six surgeons in a standardized operating technique. Results: The evaluation of the study parameters included three components: patient questionnaire (pain, patient satisfaction, ability to walk, range of motion, workplace situation), clinical evaluation (Knee Society Clinical Rating Score), conventional X-ray, and CT evaluation (axial alignment, radiolucent lines, bone defects). Conclusion: In light of the results obtained in this study, TKA implantation appears to be a valid primary treatment option in young patients with posttraumatic arthrosis. Even though the results for nearly all parameters were poorer in the posttraumatic osteoarthrosis group, the condition of these patients still improved significantly following TKA.

To substantiate the validity and relevance of the mobile-bearing knee prosthesis design compared to the fixed-bearing design, concerning the clinical outcome, this review was conducted. Articles published in 6 major orthopaedic journals were screened. Only randomized controlled trials, which investigate the clinical outcome, were included. The clinical outcome parameters of each study were analysed. Despite the numerous quantities of publications in orthopaedic literature, we could conclude, that only a few of them are randomized controlled trials. Although better kinematics of mobile-bearing knee prosthesis designs compared to fixed-bearing knee prosthesis designs are reported, no superiority of one of the bearing designs concerning clinical outcome could be revealed. Because no superiority of one of the designs concerning revision rate, survival and outcome can be found, the cheaper one should be the one to be recommended. For this reason, we advise that further research, comparing the costs and cost-benefit of mobile-bearing compared to fixed-bearing knee prosthesis designs, should be performed.

Ten-year survival of the cemented Freeman-Samuelson primary knee arthroplasty

Abstract: We report a ten-year rate of survival of 96% for the cemented Freeman-Samuelson knee arthroplasty in patients from the Swedish Knee Registry and the Royal London Hospital with revision for aseptic loosening as the criterion for failure.
