What this Trial Is About
Achilles tendon rupture is common, yet the value of popliteal nerve block for postoperative pain control during surgical repair remains uncertain. Despite widespread use, evidence supporting its analgesic effectiveness is limited, and both popliteal nerve block and Achilles tendon repair carry risks of nerve injury. This randomized, placebo-controlled trial will evaluate whether adding a popliteal nerve block to standard systemic analgesia improves postoperative pain and reduces opioid use in patients undergoing acute Achilles tendon rupture repair. Secondary outcomes will examine the incidence and impact of nerve complications on recovery, including return to physical activity and functional performance.
