Malalignment and Overload Syndromes
Anterior knee pain is one of the most common complaints that orthopedic surgeons evaluate patients for. Several conditions can cause anterior knee pain including imbalance between the quadriceps and hamstrings, patellofemoral instability, chondral wear on patella or trochlea, and lateral retinacular tightness. Fixed lateral patellar tilt due to excessive lateral retinacular tightness can result in overload of the lateral patellofemoral joint, leading to chondral degeneration and pain. Although nonsurgical treatment can frequently alleviate symptoms in the short term, patients presenting with chondral damage secondary to overload often require surgical intervention to obtain long-lasting pain relief and functional improvement. This treatment comes in the form of a tibial tubercle osteotomy with or without other concomitant procedures. This chapter will discuss the pathogenesis, diagnosis, surgical treatment, complications, and outcomes of lateral patella and trochlea overload treated with tibial tubercle osteotomy (TTO).
