About

Osteoarthritis of the knee (KOA), a common degenerative joint disease, affects a significant part of the world's population. Although it can hold all the compartments in the knee joint, isolated medial compartment involvement has been reported in about 85% of individuals diagnosed with KOA.

In the management of degenerative medial gonarthrosis; symptomatic relief and provide orthopaedic surgeons with the aim to slow down the progression of Total Knee Arthroplasty (TKA) unikompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO) is used. In recent years, HTO and UKA have been preferred more frequently among these surgical methods due to a number of advantages they provide for patients.

As a result of the orthopedic surgeries performed, interventions are made on bone and joint structures and problems may occur in the proprioceptive inputs provided by the body. In UKA, a new joint structure is created by changing the bone structure and removing the tibial plateau, while in HTO, the existing bone structure is preserved and a positional change is created. Thus, while it is expected that the proprioceptive response to be different between the two surgeries, no studies have been found in the literature on this issue. Accordingly, the purpose of this study is to compare the effects of HTO and UKA surgeries applied to individuals diagnosed with medial gonarthrosis on the proprioception of patients and to examine the effects of HTO and UKA surgeries on patients diagnosed with medial gonarthrosis.

H0: There is no difference between the surgical methods applied when the proprioception of patients with HTO and UKA surgeries planned for individuals with medial gonarthrosis is considered.

H1: There is a difference between the surgical methods applied when the proprioception of patients with HTO and UKA surgeries planned for individuals with medial gonarthrosis are considered.

Full description

Volunteer participants who have been diagnosed with medial gonarthrosis and have varus deformity and have undergone surgery will be included. The surgical groups will be divided into two categories: HTO and UKA. Evaluations of the participants in terms of proprioception will be made. A voluntary consent form will be obtained from the participants.

Enrollment: 50 estimated patients

Sex: All

Ages: 50 to 65 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Undergoing surgery at the age of 50-65
• Performing unilateral UKA or HTO surgery
• Moderate medial knee arthrosis on pre-op X-ray
• Presence of mild varus deformity in the pre-op period
• Should be BMI<30

Exclusion criteria

• Regular exercise at least 3 days a week, 150 minutes, moderate intensity
• Having undergone revision surgery
• The presence of any other orthopedic problems/problems and surgery
• Concomitant of a common rheumatological disease
• Presence of neurological problems/problems
• Having visual and auditory problems at a level that prevents communication
