Objective: To emphasize the signifi cance of Biomechanical Concepts in Orthopaedics. Design: Prospective study. Sett ing & duration of study: Th is study was carried out in Department of Orthopedic Surgery of Hamdard University Hospital Karachi from 1st October 2010 to 30th September 2013. Material & Methods: 791 patients were included in this study. All these patients were treated on the principles of biomechanics which included the management of fracture shaft s of long bones by internal intramedullary fi xation namely inter-locking nails, rigid internal fi xation by AO plates etc, treating Congenital Talipes Equino Varus (CTEV) using Ponsett i technique, management of anterior cruciate ligament injuries by applying bone-tendon-bone graft and using the optimum tensile force during recovery phase. Results: Out of 791 patients 58% were male while 42% were female. Th e age ranged from neonate to 70 years. 56 % of the patients were suff ered from soft tissue injuries while 32% of the patients had fracture. 7% of the patients had CTEV. 5% of the patients had cruciate ligament injuries. Success rate is found 92% in this study which is nearly the same i.e 96% as result of researches conducted internationally so we second the facts and fi gures of international researches. Discussion: Biomechanical Concepts in Orthopaedics are found highly signifi cant. Th eir clinical applications have provided advantages not only to the surgeon but also to the patients. Biomechanical techniques are found much more eff ective as compared to non Biomechanical techniques used for above mentioned injuries. Th e fi eld of Biomechanics should be continued to progress with its importance in orthopaedic surgery so that they remain updated with science behind these procedures. Seminars and symposiums should be carried out to generate awareness about Biomechanical techniques for under graduate and post graduate. Th e results are found 92% successfully in this study. Conclusion: It is concluded that Biomechanical Concepts in Orthopaedics are highly essential for orthopaedic surgeons in order to appreciate the mechanism of musculoskeletal system.
