Editorial Commentary: Combined High Tibial Osteotomy and Anterior Cruciate Ligament Reconstruction Yield Good Results With Unknown Effect of the Cartilage Restoration Procedure.

Realignment of the knee with high tibial osteotomy combined with anterior cruciate ligament reconstruction for a varus-deformed, anterior cruciate ligament-deficient knee yields improved International Knee Documentation Committee functional outcomes at 1 and 5 years, with cartilage restoration shown by second-look arthroscopy at 1 to 2 years. The effect of the cartilage restoration technique is still unknown, and recent literature poses a challenge to its need when realignment surgery is performed.
