“…These findings are consistent with other studies. [6][7][8][9] Τhe influence of avascular necrosis of the femoral head in comparison with idiopathic osteoarthritis (OA) on the survival of THR remains controversial. 4,19 Furthermore, the long-term survival of THR in males, and in young, active patients who usually have higher demands, remains a challenge for orthopaedic surgeons.…”

“…Several studies have reported the influence of various factors related to the patient (diagnosis, demographics, postoperative activity level) and surgical technique on THR survival. [3][4][5][6][7][8][9] However, to the best of our knowledge, there is no study examining the ability of a surgeon to predict the longevity of a THR, based on these factors.…”

Introduction: The purpose of this study was to examine the ability of a surgeon to predict survival of a total hip replacement (THR) based on the patient’s diagnosis, demographics, postoperative activity level and the surgical technique. Methods: 4 experienced hip surgeons were asked to predict the longevity of 131 Charnley THRs, performed by the senior author (GH) 22–35 years ago, by providing them with pre- and postoperative radiographs, and data concerning patient’s diagnosis, demographics, postoperative activity level and the surgical technique. This process was repeated 3 months later. Results: There was only a slight agreement between the majority of the predictions and actual outcome. The inter-observer agreement was also slight and intra-observer agreement ranged from slight to moderate. Conclusion: We confirmed that surgeons are unable to determine the life expectancy of the implants of a THR, based on the aforementioned data, because there are other non-identified factors that affect the survivorship of a THR. For this reason, regular follow-up remains the safest way to evaluate patients’ clinical picture and the evolution of radiographic changes, if there are any, in order to accurately advise patients and decide on the appropriate time for revision.

“…It should be stressed that studies with short follow-up cannot possibly be used to forecast the long-term outcome of joint replacement. Only extended follow-up studies of more than 20 years, which currently reach 40 years (2, 37), can provide this information (38). Obviously, these studies include a large proportion of censored cases, mainly due to death, that leads to biased KM survival estimations and comparisons between studies.…”

“…The method of implant fixation in total hip replacement (THR) continues to be a topic of controversy among orthopaedic surgeons. For many years, the cemented Charnley low friction arthroplasty (LFA) was considered as the gold standard (1, 2). Later, the introduction of the theory of the “cement disease” (3), although never proved, and the hypothesis that the proportion of good results with cemented THR decreased with time, led the orthopaedic community to use uncemented devices (4-13).…”

“…The purpose of the present study was to review (i) the long-term outcome of 287 cemented Charnley LFAs performed by 1 surgeon (GH), 20 to 42 years ago, in patients 60 years of age and older, using both the KM and the CI methods, and (ii) to compare the estimations of the 2 statistical methods. Part of the material (41% of the hips) has been previously published (2).…”

We concluded that fixation of implants with cement in older patients had satisfactory long-term results and can serve as a benchmark with which to compare newer fixation methods (hybrid and uncemented) and materials. However, KM method, in studies that include older population with long-term follow-up, may significantly overestimate the risk of revision and clinicians could consider using besides the cumulative incidence of competing risk method.
