Comparison of Proprioception for HTO (High Tibial Osteotomy) and UKA (Unicompartmantal Knee Arthroplasty)
- Conditions
- Knee Osteoarthritis
- Interventions
- Other: Examination of propriception
- Registration Number

- Brief Summary
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.
- Detailed 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.

Group Intervention Description High Tibial Osteotomy Examination of propriception patients who were diagnosed with medial gonarthrosis and underwent HTO surgery Unicompartmantal Knee Arthroplasty Examination of propriception patients who were diagnosed with medial gonarthrosis and underwent UKA surgery
- Primary Outcome Measures
Name Time Method Romberg Test Day 1 The patient is asked to stand in an upright position with his feet open at shoulder level and his arms free at the sides. The patient, who does not receive any support, is asked to stand first with his eyes open and then with his eyes closed. While the patient is standing still, the time until the moment when his balance is disturbed is recorded.
- Secondary Outcome Measures
Name Time Method Single Leg Stance Test Day 1 It is used to evaluate static posture and balance control. The patient should stand unaided on one leg from the moment when the other foot leaves the floor until the time when the foot touches the floor again or the arms leave the hips.
5-times Sit to Stand Test Day 1 It is used to assess the functional strength of the lower extremities, transitional movements, balance and the risk of falls. Participants are evaluated by sitting on a back-supported chair five times and holding it for a while while getting up.
change from baseline Gait Analyzer for symmetry at 8 weeks (%) Day 1 It is a smartphone-based application for analyzing walking parameters in real time. It can measure walking speed, step duration, step length, cadence and symmetry.
change from baseline Gait Analyzer for step time at 8 weeks (sec) Day 1 It is a smartphone-based application for analyzing walking parameters in real time. It can measure walking speed, step duration, step length, cadence and symmetry.
Knee Society Score Day 1 The system is divided into a knee score, which assesses only the knee joint itself, and functional scores, which assesses the patient's ability to walk and climb stairs. As a result of the dual rating system, the problem of decreasing knee scores associated with patient weakness is eliminated.
WOMAC Day 1 It is a scale that evaluates the disability associated with these conditions in hip and/or knee osteoarthritis. It consists of three parts: pain, stiffness and physical function. It contains a total of 24 substances.
change from baseline Gait Analyzer for walking speed at 8 weeks (m/sec) Day 1 It is a smartphone-based application for analyzing walking parameters in real time. It can measure walking speed, step duration, step length, cadence and symmetry.
change from baseline Gait Analyzer for step lenght at 8 weeks (m) Day 1 It is a smartphone-based application for analyzing walking parameters in real time. It can measure walking speed, step duration, step length, cadence and symmetry.
change from baseline Gait Analyzer for cadance at 8 weeks (step/min) Day 1 It is a smartphone-based application for analyzing walking parameters in real time. It can measure walking speed, step duration, step length, cadence and symmetry.
