Needle Arthroscopy vs Conventional Arthroscopy in Knees

This is a pilot randomized controlled trial will have 54 participants. The purpose of this study is to compare two surgical techniques to determine the differences in postoperative pain and early recovery in patients between 18-65 years old with simple knee pathologies including meniscal tear, chondral lesions, and loose bodies. Patient-reported outcomes and operative efficiency will be also compared. The two surgical techniques we are comparing are: 1. NanoScope™ Needle Arthroscopy for the affected knee 2. Conventional Arthroscopy for the affected knee Patients will be randomized pre-operatively but final eligibility will be confirmed intra-operatively. The study assessors and data analysts will be blinded to the treatment group via limited access to surgical records and post-operative imaging. If patients consent to participate they will be asked to come to research visits at baseline (pre-operatively), at 2-weeks, 6-weeks, and 3-month post-operatively to complete a set of questionnaires including a demographic form, SANE score, IKDC Subjective, and the EQ-5D VAS Pain, Pain and Medication Logbook will be completed from the day of surgery until day 14, and a Rehabilitation Log will assess "Return to Activity/Work". A clinical assessment will include: Range of motion, effusion, and joint line tenderness. A pre-operative X-ray and MRI will be collected as standard of care. Patients will be remunerated with a maximum of $160 if they come to all research visits.

Impact of Bone-Marrow Aspirate Injections in Knee Arthroscopy

This study will examine whether using bone marrow aspirate (BMA) during knee arthroscopy surgery can improve patient outcomes. The investigators will enroll 50 patients who need knee arthroscopy surgery for meniscus injuries or cartilage damage. Like flipping a coin, patients will be randomly assigned to one of two groups of 25 patients each. One group will receive standard arthroscopic surgery plus an injection of bone marrow aspirate, while the other group will receive standard surgery plus a saline (salt water) injection. During surgery, for patients in the treatment group, approximately 4mL (less than one teaspoon) of bone marrow will be taken from their hip bone using a special needle system. A small amount (1mL) will be sent to the laboratory for testing. Patients will be followed for 12 months after surgery and will complete questionnaires about their pain levels and knee function at several time points: before surgery, 2 weeks, 6 weeks, 3 months, 6 months, and 12 months after surgery. These questionnaires will ask about pain, daily activities, and overall improvement.

Mid- and Long-term Evaluation of the Results of Patients Undergoing Spinal Cord Stimulation With Microfractures + BST CarGel in the Treatment of Patellofemoral Chondral Lesions of the Knee

The study consists of 3 phases (Identification of eligible patients, follow-up by telephone or telemedicine platform and the collection of study-specific clinical data of enrolled patients): * Identification by trained medical personnel of subjects who meet the study inclusion criteria. * Once the patient's Informed Consent has been obtained, the study-specific questionnaires will be submitted. * Clinical score data will be collected from the questionnaires conducted at mid- and long-term follow-up of patients enrolled in the study. The data collected during the long-term follow-up will be used to evaluate the time course of the results obtained after treatment of osteochondral lesions of the patellar cartilage by spinal cord stimulation with microfractures
