Clinical Trial Summary

This clinical study aims at evaluating clinical, radiographic, patient-reported outcomes of total knee arthroplasty with Physica TT Tibial Plate in combination with Physica Porous KR or Physica Porous PS up to 2 years after surgery, in order to assess the performance of the devices. Furthermore, ithe objective is to collect short-term survivorship of the implant and the incidence of early complications.

Eligibility

Inclusion Criteria:

1. Male or female of any race requiring a total knee replacement (TKR) and suitable for receiving Physica Porous KR or Physica Porous PS femoral component in combination with Physica TT Tibial Plate.

2. Age = 18 years old.

3. Candidate for primary total knee replacement when clinical indications based on physical examination and medical history include one or more of the following

conditions:

1. Non-inflammatory degenerative joint disease like knee osteoarthritis, post traumatic knee arthritis

2. Inflammatory degenerative joint disease like rheumatoid arthritis

3. Any other medical reason for which the investigator deems the subject as a possible candidate for total knee replacement.

4. Patient has well-preserved and well-functioning collateral ligaments and one of the

following conditions:

1. Absent or not-functioning posterior cruciate ligament and severe antero-posterior instability of the knee joint (for Physica Porous PS)

2. Undamaged and functional posterior cruciate ligament (for Physica Porous KR)

5. Patient is able to understand the conditions of the study, to comply with the prescribed rehabilitation as well as willing to perform all scheduled follow-up visits.

6. Patient signed the study-specific informed consent form approved by the ethics committee before study activities

Exclusion Criteria:

1. Severe instability of the knee joint secondary to the absence of collateral ligament integrity and/or function. Only for Physica Porous KR: important joint instability and deficiency of posterior cruciate ligament.

2. Any active or suspected infection (local or systemic) or previous history of infection that may affect the prosthetic joint.

3. Previous partial knee replacement (unicompartmental, bicompartmental or patellofemoral joint replacement), patellectomy, high tibial osteotomy.

4. Significant bone loss on femoral or tibial joint side.

5. Affected by malignant cancer with life expectancy less than 2 years or where cancer treatment might affect the normal postoperative course.

6. Known incompatibility or allergy to the product materials, and/or metal hypersensitivity to implant materials.

7. Septicaemia.

8. Persistent acute or chronic osteomyelitis.

9. Open epiphyses (immature patient with active bone growth).

10. Necrotic bone

11. Arterial vascular insufficiency or nerve diseases of the lower limbs severe enough to interfere with the study evaluation.

12. Compromised bone stock due to disease, infection or prior implantation that cannot provide adequate support and/or fixation to the prosthesis.

13. Systemic or metabolic disorders leading to progressive bone deterioration, which may impair fixation and stability of the implant.

14. Any concomitant disease and dependency that might affect the performance of the implanted prosthesis.

15. Any clinically major pathology based on clinical medical history or any medical intervention or reason that the Investigator feels may affect the study evaluation.

16. Neurological or musculoskeletal disorder or disease that may adversely affect gait, functional recovery and evaluation.

17. Neuromuscular or neurosensory deficit that would hamper the performance assessment of the device.

18. Any psychiatric illness that would prevent comprehension of the details and nature of the study.

19. Simultaneously taking part in another surgical intervention study or pain management study that may affect with clinical study outcomes.

20. Female patient who is pregnant, nursing, or planning a pregnancy.

21. Important osteoporosis, haemophilic disease.

22. Internistic problems with high risk for surgery.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Knee Society Score (KSS) equal or greater than "Good" (score = 70) 2 years after surgery	0-100 scale. Scores rating from 80 to 100 are considered excellent, between 70 and 79 good, between 60 and 69 fair, and less than 60 poor	2 years after surgery
Secondary	Changes in Range of Motion over time up to 2 years after surgery		From preoperative to 2 years after surgery
Secondary	Changes in Oxford Knee Score (OKS) over time up to 2 years after surgery.	Overall score from 0 to 48, with 48 being the best outcome	From preoperative to 2 years after surgery
Secondary	Changes in Forgotten Joint Score (FJS) over time up to 2 years after surgery.	Overall score from 0 to 100, with 100 being the best outcome	From preoperative to 2 years after surgery
Secondary	Changes in Visual Analogue Scale (VAS) Pain over time up to 2 years after surgery.	100 mm line, with 0 mm being best outcome (no pain) and 100 mm worst outcome (very severe pain)	From preoperative to 2 years after surgery
Secondary	Radiographic implant evaluation and stability assessment from postoperative (baseline) over time up to 2 years after surgery	The treated knee is analyzed postoperatively based on anteroposterior and lateral x-rays view of the knee. The following parametner are evaluated: Presence of radiolucent lines; Presence of osteolysis; Presence of loosening; Presence of heterotopic ossification; Presence of periprosthetic fractures	From preoperative to 2 years after surgery
