This is a multicenter, prospective, observational, post-market clinical follow-up (PMCF) study designed to evaluate the safety and clinical performance of the Tipmed™ Primary Hip Prosthesis System in adult subjects undergoing primary hip arthroplasty. The study aims to gather real-world clinical evidence on the 24-month post-operative safety profile, potential complications, and functional outcomes of the device during routine clinical practice.

This prospective, observational, PMCF study evaluates the short-to-medium-term safety and efficacy data of the Tipmed™ Primary Hip Prosthesis System in patients undergoing primary hip arthroplasty (total or partial) across 4 clinical centers in Turkey. A total of 101 eligible participants will be enrolled in accordance with the pre-defined inclusion and exclusion criteria. Pre-operative demographic details, medical history, and surgical parameters will be captured retrospectively from patient medical charts. Following the baseline surgical procedure, subjects will undergo a 24-month clinical follow-up period consisting of 6 routine post-operative assessment windows: at 6 weeks, 3 months, 6 months, 12 months, 18 months, and 24 months. At each longitudinal visit, investigators will complete a study-specific Case Report Form (CRF) to document objective clinical indicators. Clinical performance and joint functionality will be quantitatively monitored utilizing the Harris Hip Score (HHS). Safety endpoints will be continuously evaluated by identifying, classifying, and reporting any adverse events (AEs), serious adverse events (SAEs), implant-related complications (such as dislocation, aseptic loosening, or infection), and hardware deficiencies. Radiological findings (implant orientation, migration, osteointegration) and laboratory indicators (such as C-Reactive Protein and Sedimentation Rate) will be documented when available as part of standard medical surveillance.

Demographic characteristics, clinical parameters, and efficacy/safety outcomes will be summarized using descriptive statistics. Stratified analyses will be conducted based on the specific type of primary surgical intervention. Separate subgroup analyses will be executed for study participants who undergo partial hip arthroplasty (hemiarthroplasty) to isolate and evaluate their outcomes independently from the patients treated with total hip arthroplasty. Categorical variables across these subgroups will be compared using the Chi-square test or Fisher's exact test, as appropriate.

Inclusion Criteria:

• Individuals aged 18 years and older,
• Male or female participants,
• Subjects who have undergone Primary Hip Arthroplasty (either total or partial) for any indication,
• Subjects in whose surgical procedure the Tipmed™ Primary Hip Prosthesis System components were utilized.
• Subjects who are not legally restricted (e.g., military personnel, convicts, or individuals under legal guardianship).
• Subjects who have voluntarily signed the written Informed Consent Form (ICF).

Exclusion Criteria:

• Subjects currently participating in any other interventional clinical trial.

The study population comprises adult patients aged 18 years and older, of both sexes, who have undergone primary hip arthroplasty (either total or partial) at participating multi-center orthopedic clinics. The cohort specifically represents individuals whose surgical treatment involved the standard clinical implantation of the Tipmed™ Primary Hip Prosthesis System component options. Eligible individuals who are legally competent and provide written informed consent to allow their routine post-operative clinical, laboratory, and radiographic data to be documented will be consecutively enrolled.
