High tibial osteotomy is an efficient treatment for medial compartment osteoarthritis of the knee; its used for middle aged patients with high activity levels and can delay the need for total arthroplasty.

The results of total knee arthroplasty after failed high tibial osteotomy are controversies; several authors reported inferior outcomes, but others have concluded that tibial osteotomy doesn't bias following total arthroplasty. The aim of this study was to evaluate the results of failed high tibial osteotomy subsequently converted to total knee arthroplasty and compare the results to group of patients underwere primary arthroplasty; the authors evaluate some of technical problems that a previous high tibial osteotomy can generate, like scar tissue, patellar tendon shortening and changes of proximal tibial anatomy.

Methods: 50 total knee arthroplasty performed after a previous closed wedge osteotomy were matched with 50 patients operated with a primary knee prosthesis for osteoarthritis. The time from a proximal tibial osteotomy to a prosthesis operation was in mean eight years.

Results: the Knee Society clinical and radiographic score system and W.O.M.A.C. evaluation were used to evaluate knees before surgery and at each follow up (average 5 years).

At an average of five years follow up, the clinical results of total knee arthroplasty after high tibial osteotomy were similar to those of primary knee prosthesis.

Discussion: in our study revision of failed proximal tibial osteotomy appears to have more technical difficulties but with overall outcomes that remain comparable at results after primary total knee arthroplasty, so tibial osteotomy is considered a valid option in younger and very active patients with unicompartmental arthritis.

Introduction: A prospective study was done to compare the early clinical, radiographic outcomes between the Scorpio CR and Scorpio Flex CR primary total knee replacement.

Methods: 130 Scorpio CR and 40 Scorpio Flex CR were implanted. Patients were prospectively evaluated with a mean follow-up of 3,9 years (2–8 years). Knee Society Score, W.O.M.A.C., range of motion and knee pain was compared. Patients age, level of activity, BMI, were criteria selection for implant of Scorpio Flex CR.

Results: There was more pain in Scorpio CR group, mean flexion was greater in Scorpio Flex CR (112 vs 108); Knee Society score and WOMAC was better in Scorpio Flex CR group.

Conclusion: The Scorpio Flex CR new design may be allow the significant increase in Knee Society score and the better ROM in Scorpio Flex CR group.

Obesity is strongly linked to osteoarthritis; can affect the outcome of total knee arthroplasty and can increase the load on the components with reduction of the implant’s survivorship.

The purpose of this study is to compare clinical and radiographic outcomes in obese (defined as BMI > 30) and non obese patients.

The Knee Society scoring system and WOMAC was used to evaluate the knees preoperately and at latest follow up.

With a follow up ranging from 1 to 5 years, Knee Society score and WOMAC for the patients who were obese were lower than non obese patients.

Non progressive radiolucent lines were located adjacent to the tibial component in the group of obese patients, but without clinical significance.

Introduction: Quality of life is becoming in the last years an essential element of evaluation of treatments. The aimof this prospective cohort study is to assess the quality of life and the speciþc patient perspective on knee replacement. A pre- and post-operative patient-oriented study was conducted on patients operated on knee replacement for symptomatic knee arthritis to measure their quality of life. Material and Methods: There were 50 patients, mean age 71.3 (5.1 SD) years, affected by knee arthritis. The SF-36 questionnaire (ofþcial Italian version) and Oxford validated Italian version questionnaire (OKQ) were administered preoperatively and post-operatively (at 2 years of follow-up Ð SD 1.5). The results were compared within and with those of an age-matched and sex healthy sample (n=351) published in Literature. The appropriated statistical analysis was used on results data. Results: The SF-36 domain scores for the pre- and post-operative data were respectively the following: PF 32.50±24.43 and 50,81±27.21; RF 13.63±28.58 and 63.09±47.18; BP 14.47±11.44 and 50.45±28.61; GH 55.08±15.36 and 56.71±20.29; VT 44.77±15.77 and 58.19±16.84; SF 55.08±25.15 and 71.81±25.60; RE 42.00±46.31 and 65.09±40.14; MH 58.72±16.85 and 61.71±20.14; PCS 27.00±6.22 and 38.71±9.51; MCS 46.13±11.10 and 47.76±9.43. The OKQ respectively 47.00±7.86 and 27.72±10.66. Appropriated statistical tests were performed. Conclusions: Knee replacement signiþcantly improve patientsñ perception of their own health. Moreover the patient-oriented speciþc measure give results really reassuring on knee replacement results. A better knowledge of the health status changes induced by knee replacement might help further deþne the indications to surgery and cost-beneþt relationship.
