Joint preservation procedures: osteotomies about the knee.

Osteotomies around the knee are an effective method for preserving the knee joint by correcting overall alignment. Although osteotomies have historically been used in treatment of knee pathology, they have recently regained a renewed interest as a treatment strategy for alignment correction, ligamentous stability, and cartilage preservation. Osteotomies are a powerful way to correct alignment in both the sagittal and coronal plane to preserve and/or protect the cartilage in the medial, lateral, and patellofemoral compartments of the knee and improve the ligamentous stability of the knee.

Technical Tips and Tricks for Knee Osteotomy.

Osteotomies around the knee have a variety of indications, including pain reduction, functional improvement, knee joint stabilization, and articular cartilage preservation. Thorough preoperative planning is essential, including a determination of the precise location of any deformity (proximal tibia, distal femur, or both). High tibial osteotomies and distal femoral osteotomies can be performed in isolation, or jointly in the form of a double-level osteotomy, for correction of coronal and/or sagittal deformity of the knee.

Comparison of Revision and Redislocation Rates After First-Time Anterior Shoulder Instability Between Subluxators and Dislocators: A Midterm Outcome Study.

Purpose: To compare revision and redislocation rates as well as patient-reported outcomes (PROs) between subluxators and dislocators after a first-time anterior shoulder instability event.

Soft tissue mass resembling myxochondroid metaplasia in Achilles tendon.

The Achilles tendon is the strongest and largest tendon in the human body, composed of the distal confluence of the gastrocnemius and soleus muscles and may also include the plantaris longus tendons. Despite its tremendous strength, it is frequently injured. Soft tissue tumors or tumor-like conditions of Achilles tendon are much less common in comparison to traumatic and infectious/inflammatory lesions.

Primary Anterior Cruciate Ligament Injury: Extrinsic and Intrinsic Risk Factors.

Anterior cruciate ligament (ACL) injuries continue to increase in incidence despite extensive research into prevention strategies. Many extrinsic and intrinsic risk factors for sustaining ACL injuries have been identified and continue to be investigated. Extrinsic risk factors for ACL injury relate to the athlete's environment, such as the shoe-surface interaction, weather conditions, and sport played.
