      We reviewed our experience with total knee arthroplasties performed between 1977 and 1992 in patients who were fifty-five years old or less to determine the appropriate management for younger patients who have severe osteoarthrosis. One hundred and fourteen knee replacements were performed in eighty-eight patients who were an average of fifty-one years old (range, twenty-two to fifty-five years old). All of the operations were performed by one of the two senior ones of us (J. N. I. or W. ...

      One hundred thirty five patients with osteoarthritis who underwent total knee arthroplasty (TKA) were evaluated to determine whether specific pre- and postoperative variables were correlated with the postoperative range of motion. Age, sex, pre- and postoperative range of motion, pre- and postoperative Knee Society scores, intraoperative patellar thickness before and after resurfacing, pre- and postoperative radiographic patellar height (as determined by the Insall-Salvati and ...

      The long-term results of use of the posterior stabilized total knee prosthesis were evaluated with regard to clinical performance, survival of the implant, polyethylene wear, osteolysis, and loosening. One hundred and twenty patients had 165 primary total knee arthroplasties, with insertion of a posterior stabilized total knee prosthesis with a metal-backed tibial component with cement, between March 1981 and March 1983. Thirty-seven patients (fifty-three knees) subsequently died, five ...

      Flexion and extension gap heights were measured in 50 consecutive primary posterior-stabilized total knee arthroplasties (TKAs) to determine whether posterior cruciate ligament (PCL) release or re-establishment of the posterior condylar recess increased gap width. After PCL release, a slight symmetrical increase was noted in both gaps. In extension, gap width increased on average 1.3 mm and 1 mm in the medial and lateral compartments, respectively. The same pattern was observed in ...

      The purpose of the current study was to review results of primary constrained condylar knee arthroplasty in elderly patients with genu valgum deformity. The hypotheses were: (1) constraint has no adverse effects in elderly patients; (2) treating deformity with a constrained condylar knee prosthesis in lieu of lateral ligament release avoids morbidity, particularly peroneal nerve palsy and flexion instability; and (3) press-fit noncemented stem extensions enhance fixation of the cemented ...

      The current study analyzed subjects having a total knee arthroplasty to determine the incidence of condylar lift-off and correlate lift-off with the alignment of the femoral component with respect to the transepicondylar axis. Twenty-five subjects, implanted with a posterior stabilized total knee prosthesis, were asked to do weightbearing deep knee bends while under fluoroscopic surveillance. The two-dimensional fluoroscopic images were converted into three-dimensional images using a ...

      The survivorship method of analysis was used to compare the failure rate and overall success of 2629 cemented primary total knee arthroplasties during a 22-year period by the senior surgeon. There were 215 Total Condylar prostheses with a polyethylene tibia, 265 of the Posterior Stabilized type with an all polyethylene tibia, 2036 Posterior Stabilized with a metal backed tibial component, 49 Posterior Stabilized with modular augmented components, and 64 with the Constrained Condylar ...

      The 10-year results of primary total knee arthroplasty in patients who were obese were evaluated. In a 2-year period, 120 patients had 165 primary, posterior stabilized, cemented total knee replacements with metal backed tibial components. After exclusions, 56 patients (73 knees) were available for study. Twenty-two patients (32 knees) were classified as obese, and 34 patients (41 knees) were classified as nonobese. At 10 years followup, patients who were obese had lower Knee Society ...

      We evaluated the utility and safety of arthroscopy for diagnosing and treating symptoms in problematic total knee replacements. From 1988 to 1995, 40 arthroscopies were performed on 38 patients with an average age of 68.4 years. The average onset of symptoms post knee replacement was 33.7 months (range 1 month to 15 years), and the average duration of symptoms prior to arthroscopy was 15.6 months (range 1 month to 5 years). Presenting symptoms included pain in 73%, catching or soft ...

      From 1974 to 1986, 1430 cemented primary total knee arthroplasties were available for analysis. These included 224 total condylar prostheses with a polyethylene tibial component, 289 posterior stabilized prostheses with a polyethylene tibial component, and 917 posterior stabilized prostheses with a metal-backed tibial component. There were 12 failures in the total condylar series including three infections (one early and two late), five loose tibial components, two loose femoral and ...

      We reviewed the results of seventy-six revision total knee replacements, performed between 1980 and 1988 on the Knee Service at The Hospital for Special Surgery, in seventy-four patients. Sixty-five patients (sixty-seven knees; 88 percent) had a complete clinical examination and radiographic evaluation, and nine patients (nine knees; 12 percent) were only interviewed by telephone. Survivorship analysis was performed for all patients. The average duration of follow-up was three years and ...

      Fourteen patients with a posterior-stabilized prosthesis in one knee and a posterior cruciate-retaining prosthesis in the contralateral knee and both scoring good or excellent on the Hospital for Special Surgery (HSS) knee scale were evaluated by isokinetic muscle testing and comprehensive gait analysis at a mean follow-up of 98 months after arthroplasty. The average HSS knee score (93 points) and the average Knee Society score (94 points) were the same for the cruciate-retaining and ...
