An observational study in Total Hip Arthroplasty (THA), Hemiarthroplasty and Osteoarthritis (OA) of the Hip, sponsored by TIPMED Medical Device Manufacturing Ltd. Co.. Recruiting at 4 sites in Turkey (Türkiye). Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-06-16.
Sponsored by TIPMED Medical Device Manufacturing Ltd. Co. · Observational
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.
2,974 studies on the registry are indexed under Osteoarthritis; 438 are open to participants now.
This study's planned enrollment of 101 is close to the median of 100 across 601 observational studies indexed under Osteoarthritis.

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.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

A single prospective cohort of adult patients tracked during routine clinical practice who have undergone primary hip arthroplasty (either total hip arthroplasty or partial hemiarthroplasty) using the Tipmed™ Primary Hip Prosthesis System (including cemented or uncemented stem options based on standard surgical indications).
Device: Tipmed™ Primary Hip Prosthesis System
Post-market utilization of the commercially available Tipmed™ Primary Hip Prosthesis System during routine orthopedic care. Device components include various configurations such as cemented or uncemented stems (anatomic or square cross-section), acetabular cups, bipolar cups, and titanium metal shells fitted according to standard clinical routine and patient anatomy. No investigational or non-routine interventions are performed as part of this observational registry.
Functional Joint Performance via Harris Hip Score (HHS) at 24 Months
The proportion of participants achieving "Excellent" (≥ 90 points) or "Good" (80-89 points) clinical performance based on the Harris Hip Score (HHS) will be evaluated. The HHS is a clinician-administered tool that quantitatively scores hip function across domains including pain, function, functional activities, absence of deformity, and range of motion (ROM), with a total score ranging from 0 (worst possible outcome) to 100 (best possible outcome).
Time frame: 24 months post-operatively.
Incidence of Adverse Events (AEs) and Serious Adverse Events (SAEs)
Continuous monitoring, documentation, and cumulative tracking of the incidence of all adverse events (AEs) and serious adverse events (SAEs) occurring throughout the study period, regardless of their causal relationship to the investigational medical device or surgical procedure. Events will be systematically classified by severity (mild, moderate, severe), outcome, and causality pattern.
Time frame: From the signing of informed consent up to 24 months post-operatively.
Incidence of Clinical Complications
Evaluation of the rate, frequency, and types of all complications recorded throughout the study period. This includes intraoperative complications captured retrospectively from surgical medical records (such as femoral or acetabular fractures, vascular injuries, and nerve lesions) as well as longitudinal complications documented during the follow-up phase (such as joint dislocation, aseptic loosening, implant breakage, or deep and superficial surgical site infections) associated with the routine clinical utilization of the Tipmed™ Primary Hip Prosthesis System.
Time frame: From the time of signing the informed consent form up to 24 months post-operatively.
Longitudinal Changes in Hip Functioning via Harris Hip Score (HHS)
Periodic monitoring of absolute HHS tracking metrics and category shifts to determine the trajectory of functional recovery over time. The total HHS ranges from 0 (worst possible outcome) to 100 (best possible outcome) and is categorized as follows: Excellent (90-100); Good (80-89); Fair (70-79); Poor (60-69); and Very Poor (\<60). Transition tables will be generated utilizing these classifications to map longitudinal shifts from the retrospectively captured pre-operative baseline value (extracted from patient medical charts) across all prospective post-operative follow-up intervals.
Time frame: Retrospective pre-operative baseline, and prospective assessments at 6 weeks, 3, 6, 12, 18, and 24 months post-operatively.
Plan to share: No — Individual Participant Data (IPD) will not be shared publicly due to the strict confidentiality requirements, personal data protection legislation (KVKK Law No.6698), and commercial intellectual property rights policies of the sponsor.

Of 82 industry-sponsored observational studies under Osteoarthritis, half reached primary completion within 93 months of starting (the median), counting those still running; a quarter within 43 and three quarters within 184. This study's planned 57 months is below that.
Counting every sponsor, half of 228 studies reached it within 57 months; a quarter within 21 and three quarters within 141.
