Title: Personalized Total Knee Arthroplasty: Computer-Assisted Navigation vs. Robotic Assistance (CAN-ARD). Summary: Knee osteoarthritis is frequently treated with Total Knee Arthroplasty (TKA). However, approximately 20% of patients remain dissatisfied following the procedure. This study aims to compare two surgical assistance technologies designed to improve prosthetic placement accuracy: Computer-Assisted Navigation (CAN) and Robotic-Arm Assistance (RA). The primary objective is to determine if there is a significant difference in functional outcomes and the "forgotten joint" sensation (measured by the Forgotten Joint Score - FJS) between patients operated on with robotic assistance versus those with traditional navigation at 3, 12, and 24 months post-surgery. The study's hypothesis is that there is no major clinical difference between these two techniques when applied within a personalized alignment strategy.

Pudendal neuralgia (PN) is a chronic nerve compression syndrome causing neuropathic pain. Treatment includes medication, infiltration and decompressive surgery. Medicinal treatment involves the use of drugs that have proved effective in other areas, such as shingles or diabetes. There is no consensus on the molecules to be used for pudendal nerve infiltration (PNTI), and less than half of patients experience short-term relief. The only risk factor for failure is the duration of pain. Our study proposes to compare the usual treatment with a placebo, as no type of infiltration has been compared with a placebo.

The goal of this clinical trial is to evaluate the efficacy of a posterior perineal block performed under neurostimulation at 1 month after local anesthetic infiltration in the treatment of chronic idiopathic ano-perineal pain. The main questions aims to answer are : 1. The efficacy of a posterior perineal block performed under neurostimulation on pain 1 month after local anesthetic infiltration in the treatment of chronic idiopathic ano-perineal pain. 2. The rate of maintenance at 3 months of a positive response to the first infiltration. 3. The pain-free rate at 1 month after the first infiltration. 4. Evolution of quality of life and pain impact between inclusion and one month after the first infiltration. 5. Changes in anxiety and depressive disorders associated with pain between inclusion and one month after the first infiltration. 6. The evolution of symptoms related to central sensitization (both somatic and emotional) between inclusion and one month after the first infiltration. Participants will : * be managed with a posterior perineal block of lidocaine or saline solution under neurostimulation. * complete a questionnaire on pain, anxiety and depression at inclusion and one month after injection of the research product (lidocaine or saline solution). Researchers will compare between the two treatment arms (lidocaine versus saline solution) to see the rate of patients with a reduction of at least 3 points on a visual analog pain scale between inclusion and 1 month after the first injection.

Management of prosthetic joint infections (PJI) is a challenging task. These infections include different clinical and microbiological settings calling upon various treatment strategies according to infection type (acute or chronic), bone quality, the involved micro-organism and the patient's general condition and willing. Treatment of PJI combines surgery and prolonged antibiotic therapy. In some patients with a high operative risk prolonged suppressive antibiotic therapy can be used. Lack of large prospective studies motivated the conception of this cohort with a long term follow up, regardless to PJI management procedures.

CHIMOVIP is a study to determine the best therapeutic strategy in patient with ovarian advanced cancer.
