Closing wedge HTO is a realignment surgery around the upper tibia (shinbone) to change how forces pass through the knee. It removes a wedge-shaped piece of bone and closes the gap to shift the leg’s alignment. It is most commonly used for knee pain related to uneven loading in the medial (inner) compartment of the knee. It is one type of high tibial osteotomy (HTO) used in knee preservation care.

Opening wedge HTO is a knee realignment surgery that changes how weight is distributed across the knee joint. It involves creating a controlled “opening” on the upper tibia (shinbone) to shift the leg’s alignment. It is commonly used for knee pain related to uneven joint loading, especially in varus (bow-legged) alignment. The goal is typically to preserve the patient’s own knee joint rather than replace it.

HTO most commonly refers to **high tibial osteotomy**. It is a **knee realignment surgery** that changes how body weight travels through the knee joint. It is most often used for **knee pain related to uneven load and early arthritis**, especially on one side of the knee. It is commonly discussed in orthopedics, sports medicine, and knee preservation care.

High tibial osteotomy is a knee-alignment surgery that reshapes the upper tibia (shinbone) near the knee. It is commonly used to shift weight away from a worn or painful side of the knee joint. The goal is to reduce symptoms and improve function by changing how forces pass through the knee. It is most often discussed in the setting of one-sided (compartmental) knee arthritis or malalignment.

Cartilage repair is a set of treatments designed to address damage to joint cartilage. It aims to reduce symptoms and improve function by restoring or replacing injured cartilage surfaces. It is most commonly discussed for the knee, but it can apply to other joints as well. It may involve rehabilitation, injections, or surgery depending on the lesion and the patient.

Subchondroplasty is a minimally invasive orthopedic procedure used to treat certain painful problems in the bone just under joint cartilage. It is most commonly discussed in relation to the knee. It typically involves injecting a bone substitute material into areas of damaged subchondral bone. It is often performed alongside arthroscopy to evaluate the inside of the joint.

Biocartilage augmentation is a cartilage-repair technique that adds a cartilage-based scaffold to a joint surface defect. It is most commonly used in the knee to support treatment of small, focal areas of damaged articular cartilage. It is typically performed as an adjunct to a marrow-stimulation procedure (such as microfracture) during arthroscopy.

Chondral resurfacing is a group of treatments that aim to restore or replace damaged joint cartilage. It is most commonly discussed for the knee, especially after injury or wear-related cartilage breakdown. The goal is to improve the joint surface where cartilage has become rough, thinned, or missing. It is used in sports medicine and orthopedic practice to manage focal cartilage defects and related symptoms.

Chondroplasty is a surgical technique used to smooth and stabilize damaged joint cartilage. It is most commonly performed arthroscopically (through small incisions) in the knee. The goal is to reduce irritation from rough or unstable cartilage surfaces. It is often done during the same procedure as other knee arthroscopy treatments.

Matrix-induced ACI is a surgical cartilage repair technique that uses a patient’s own cartilage cells on a scaffold. It is commonly used for focal cartilage defects in the knee. The goal is to restore a smoother joint surface where cartilage has been damaged. It is typically discussed in sports medicine and orthopedic cartilage restoration care.
