Inclusion criteria
1. Male and female subjects 50 years of age or older and less than 85 years of age (\>50 and \<85 years) who are candidates for primary cemented total knee replacement based on physical examination and medical history, including diagnosis of severe knee pain and disability due to at least one of the following causes: * to. Primary or secondary osteoarthritis * b. Collagen disorders and/or avascular necrosis of femoral condyle * c. Moderate valgus, varus or flexion deformities (HKA between ± 10°, flexion contracture \<10°) - 2. Patients consent and able to complete scheduled study procedures and follow-up assessments. 3. Patients informed about the nature of the study who signed the "informed consent" approved by the ethics committee.
Exclusion criteria
* Simultaneous participation in other studies * Patients not capable of understanding and wanting and therefore unable to sign the informed consent * Patients who have already undergone hip or ankle arthroplasty, previous osteotomy, with severe axial deformities or suffering from rheumatoid arthritis, diabetes or neuromuscular diseases.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Knee Society Score | at baseline (day 0) | Two sections, one evaluating the patient's function and one for his clinical conditions, overall score goes from 0 to 100 |
| Western Ontario and McMaster Universities Arthritis Index | at baseline (day 0) | The test evaluates main aspects of arthritis such as pain, stiffness articulation and functionality. The score goes from 0 to 96 |
| Knee injury and Osteoarthritis Outcome Score | at baseline (day 0) | The KOOS holds five separately scored subscales: Pain, other Symptoms, Function in daily living (ADL), Function in Sport and Recreation (Sport/Rec), and knee-related Quality of Life (QOL). the score goes from 0 to 100 |
| 36-Item Short Form Health Survey | at baseline (day 0) | is a valid and reliable tool for measuring health outcomes in patients with musculoskeletal pain, but its sensitivity to clinical changes in patients with specific disorders may be limited, rated on a scale of 0 to 100, with 0 and 100 being minimum and maximum possible scores. |
| Forgotten joint score | at baseline (day 0) | a 12-question patient-reported outcomes measure created to measure a patient's awareness of their artificial joint |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Radiographic evaluation of prosthetic femoral component positioning | 5 days after index surgery | measurement of prosthetic femoral component alignment according to femoral mechanical axis |
