Does Surgical Approach Matter in Arthroplasty? A Surgeon's Perspective from Exposure to Execution

Introduction: Orthopedic surgeons often debate approach as though the incision itself determines outcome: Direct anterior versus posterior total hip arthroplasty (THA), or medial parapatellar versus quadriceps-preserving total knee arthroplasty (TKA). In practice, the approach is the operating platform on which every subsequent decision is made. It determines visualization, retraction, soft-tissue release, component access, the ease of restoring biomechanics, and the surgeon's ability to manage difficulty. In direct anterior THA, the skin incision is rarely the limiting step; femoral mobilization is. In direct anterior approach THA, a reproducible supine workflow, controlled capsular and peri-femoral release, appropriate leg positioning, fluoroscopic verification, and a willingness to enlarge or extend exposure when required are more important than preserving the label of "minimally invasive." Our recent experience in younger, osteonecrosis-dominant Indian cohorts also supports a pragmatic rather than dogmatic approach to capsular management and emphasizes the importance of surgeon experience and standardized technique. In TKA, the same principle applies differently: The arthrotomy matters, but the final reconstruction is determined more by bone resection, alignment philosophy, gap balance, and soft-tissue preservation. Robotic assistance makes these variables measurable and reproducible, but it cannot rescue poor exposure or replace surgical judgment. In our robotic workflow, we favor a bounded, phenotype-respecting strategy that minimizes bone resection and soft-tissue release while balancing gaps rather than forcing every knee to neutral mechanical alignment. Current evidence suggests that such functional alignment strategies can reduce releases, although consistent superiority in patient-reported outcomes remains unproven. Surgical approach therefore matters - not because one named approach is universally best, but because it sets the biological and mechanical conditions, in which a safe, accurate, and reproducible reconstruction must be achieved.
