This study investigates the influence of sexual counseling using the PLISSIT model on various aspects of patients undergoing hip replacement. The PLISSIT model is employed to guide the counseling process. The research aims to assess how this counseling intervention affects sexual function, quality of life, and overall comfort for these patients. By addressing these factors, the study seeks to shed light on potential improvements in the well-being and experiences of individuals who have undergone hip replacement surgery.

To ensure the proper functioning of the body's systems and the fulfillment of an individual's needs, sufficient movement function is necessary. Decreased movement function, which is crucial for numerous physiological processes, negatively affects overall health status and vital functions. The hip joint is subjected to stress from activities such as walking, running, climbing stairs, lifting weights, and squatting throughout the day. Additionally, conditions like osteoarthritis and rheumatoid arthritis, which emerge with aging, lead to structural and functional abnormalities in the hip joint.

The severe pain and limited movement resulting from issues in the hip joint adversely impact daily life activities, diminishing quality of life. To alleviate pain, improve movement restrictions, and enhance quality of life, Total Hip Arthroplasty (THA) is one of the treatment options. Presently, due to advancements in surgical techniques and materials, THA has become a widely employed method. Literature also indicates increased comfort levels and improved quality of life for individuals after surgery.

One significant component of overall quality of life and general health is a healthy sexual function. Pain and movement limitations in the hip joint also negatively influence individuals' sexual lives. Stiffness, restricted movement, and severe pain in the hip joint lead individuals to be concerned about initiating sexual activity. Studies have shown that after Total Hip Arthroplasty, most patients experience an increase in sexual activity. With the elimination of pain and movement restrictions, individuals engage more comfortably in sexual activities.

However, despite the positive effects of total hip replacement, patients tend to avoid sexual activity due to factors like delayed wound healing, dislocation, joint noises, and uncertainty about resuming sexual relations. Individuals who cannot perform their sexual functions in a healthy manner are negatively affected both physically and psychologically. Moreover, the inability to experience a healthy sexual life, an integral part of marriage and intimate relationships, disrupts the connection between partners. Engaging in sexual activity at the wrong time or in inappropriate positions after surgery can increase the risk of dislocation and reoperation.

Due to all these reasons, the post-operative recovery process and patient comfort are adversely affected. Therefore, in the nursing care provided during the rehabilitation process after total hip replacement, individuals' sexual functions should not be overlooked. Collecting data on patients' sexual functions post-surgery and offering sexual counseling based on their needs are necessary. Detecting and resolving sexual issues are crucial for an effective and expedited post-operative rehabilitation and recovery process. This approach will contribute to the improvement of individuals' physical, social, and psychological health, leading to increased quality of life and comfort levels.

The use of models is highly important in evaluating and resolving individuals' sexual health. The utilization of the PLISSIT model is recommended in providing sexual counseling to healthcare professionals due to its ease of use and systematic approach. The PLISSIT model, developed by Annon in 1976 to guide the resolution of sexual issues, was revised by Taylor and Davis in 2006. The model consists of four stages: P-Permission, LI-Limited Information, SS-Specific Suggestions, and IT-Intensive Therapy.

P (Permission) - Permission: Boundaries for what individuals can and cannot discuss regarding sexuality should be established. In cases where these boundaries are not defined, individuals may not know what they should discuss. In this stage, nurses should allow patients to express their concerns about sexuality and sexual health and encourage them to do so.

LI (Limited Information) - Limited Information: The interventions in this stage aim to inform individuals about sexual matters. This stage involves reviewing the individual's knowledge about sexuality, discussing the effects of the disease and treatments on sexual function, providing information about these effects, and addressing concerns. Providing accurate information helps individuals cope more easily with their concerns about sexuality.

SS (Specific Suggestions) - Specific Suggestions: This stage includes providing individuals/spouses with specific information and recommendations for a more fulfilling sexual life. It is particularly effective for arousal and orgasm disorders and dyspareunia. The recommendations to be made depend on the sexual problem information obtained from the individual. Detailed recommendations such as different positions, interventions, and lubricants can be suggested to individuals with sexual problems.

IT (Intensive Therapy) - Intensive Therapy: This stage is the final stage of the PLISSIT model. If the first three stages of the model are unsuccessful, the intensive therapy stage is employed. The counselor needs to be an expert who has received additional training or should refer the individual to an appropriate unit to provide intensive therapy.

In the literature, it is generally observed that sexual counseling based on the PLISSIT model is provided to women experiencing sexual dysfunction due to reasons such as pregnancy, postpartum, hysterectomy, and mastectomy. Although studies have been conducted worldwide and in our country regarding sexual function after total hip replacement surgery, no study has been found that specifically provides sexual counseling based on the PLISSIT model.

Inclusion Criteria:
