Tiny camera could make knee surgery less painful

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * • Clinical diagnosis of: Meniscal tears (Medial or Lateral) suitable for partial meniscectomy or simple repair; Chondral lesions / Chondromalacia (ICRS Grade 1-3); Loose bodies; Synovitis requiring synovectomy; Cyclops lesion (post-ACL reconstruction). * Age: 18 to 65 years at time of surgery. * Imaging: Pre-operative MRI performed within 6 months of the surgery date. And an X-ray showing no fractures. * Consent: Willingness and ability to provide informed consent and attend follow-up visits. Exclusion Criteria: * • Instability: Concomitant ACL, PCL, or multi-ligament injury requiring reconstruction (reconstruction cannot be performed solely with NanoScope). * Osteoarthritis: Advanced Osteoarthritis defined as Kellgren-Lawrence Grade 3 or 4 (bone-on-bone) on pre-operative weight-bearing radiographs. * Complex Pathology: Complex meniscal tears requiring repair techniques strictly requiring standard instrumentation (e.g., large bucket-handle tears requiring inside-out/outside-in sutures). * Infection: Active local or systemic infection. * BMI: Body Mass Index \> 40 (due to potential visualization difficulties with the 1.9mm system in deep soft tissue). * Previous Surgery: Revision meniscal repair on the affected compartment (unless simple debridement). * Legal/WCB: Patients involved in active litigation or Workers Compensation Board (WCB) claims. * Language: Unable to speak, read, or understand English (preventing completion of PROMs). * Pregnancy: at the time of surgery. * Mental Health: Conditions that preclude informed consent and follow-up (e.g. mental capacity, impaired judgment and/or memory, severe mood episodes, dementia, etc). * Major illness: Life expectancy \<1yr or unacceptably high surgery risk). Intra-operative exclusions: Final assessment of eligibility will be made intra-operatively and include: * Arthritis: If grade 3 or 4 chondral damage (exposed bone) is discovered intra-operatively that was not evident on radiographs, the patient may be excluded from the per-protocol analysis but retained for safety analysis. * Technique Failure (Crossover): If a patient randomized to the NanoScope Group has pathology that cannot be adequately visualized or treated with the needle system (e.g., tight compartment, excessive bleeding, or inability to access pathology), the surgeon will convert to Conventional Arthroscopy. These patients will be considered "enrolled" and analyzed in their original randomized group (Intention-to-Treat principle), but the case will be documented as a "Failure of Technique".
