Detailed Description

This prospective, multi-center, observational, Post-Market Clinical Follow-Up (PMCF) study evaluates the short-to-medium-term safety and efficacy data of the Tipmed™ Revision Hip Prosthesis System in adult patients undergoing revision hip arthroplasty (total or partial) across participating clinical centers in Turkey. A total of 35 eligible participants will be enrolled in accordance with the pre-defined inclusion and exclusion criteria. Pre-operative demographic details, comprehensive medical history, previous arthroplasty data, and specific indications for revision surgery (such as aseptic loosening, infection, dislocation, or periprosthetic fractures) will be captured retrospectively from patient medical charts. Following the baseline revision 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 and survival indicators. Clinical performance and joint functionality profiles 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 (including re-revision rates, dislocation, aseptic loosening, infection, or nerve/vascular injuries), and hardware deficiencies. Radiological findings (implant positioning, component orientation, migration, osteointegration, and status of acetabular/femoral bone loss) and laboratory indicators (such as C-Reactive Protein and Sedimentation Rate) will be documented when available as part of standard medical surveillance.

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

Tıpmed™ Revision Hip Prosthesis
A single prospective, multi-center, non-interventional cohort of adult patients tracked during routine clinical practice who have undergone revision hip arthroplasty using the Tıpmed™ Revision Hip Prosthesis System. Patients are enrolled following revision surgery indicated for clinical complications such as aseptic loosening, periprosthetic infection, joint instability, dislocation, or periprosthetic fractures. The cohort captures real-world clinical data based on standard orthopedic indications without any study-mandated modifications to the routine surgical choice.
Device: Tıpmed™ Revision Hip Prosthesis System
Post-market evaluation of the commercially available, CE-marked Tıpmed™ Revision Hip Prosthesis System during routine revision orthopedic care. Surgeon-directed device configurations are utilized based on patient-specific bone loss and anatomy, incorporating various mono-block or modular femoral stems, modular femoral body components, and femoral necks. Acetabular reconstruction elements encompass various configurations including acetabular cups, bipolar cups, and titanium metal shells with modular inserts, paired with dedicated bone-anchoring options such as acetabular rings, reinforcement cages, and anatomical rings based on standard clinical routine. In strict adherence to the prospective observational design of this registry, no investigational, experimental, or non-routine surgical interventions are performed.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Functional Joint Performance via Harris Hip Score (HHS) at 24 Months
Time Frame: 24 months post-operatively
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 to demonstrate device efficacy. 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).
24 months post-operatively
Incidence of Adverse Events (AEs) and Serious Adverse Events (SAEs)
Time Frame: From the signing of informed consent up to 24 months post-operatively.
Continuous monitoring, documentation, and cumulative tracking of the incidence and frequency of all adverse events (AEs) and serious adverse events (SAEs) occurring throughout the study surveillance period, regardless of their causal relationship to the investigational revision medical device or surgical procedure. Events will be systematically classified by intensity/severity (mild, moderate, severe), outcome characteristics, and causality relationship pattern.
From the signing of informed consent up to 24 months post-operatively.
Incidence of Clinical Complications
Time Frame: From the time of signing the informed consent form up to 24 months post-operatively.
Evaluation of the rate, frequency, and types of all clinical complications recorded throughout the study. This includes intraoperative complications captured retrospectively from surgical medical charts (such as femoral or acetabular perforation/fractures, vascular injuries, and nerve lesions including peroneal or sciatic nerve injuries) as well as longitudinal complications documented during the prospective follow-up phase (such as joint dislocation, aseptic loosening, implant failure/breakage, deep or superficial surgical site infections, and subsequent re-revision/reoperation rates) associated with the routine clinical utilization of the Tıpmed™ Revision Hip Prosthesis System.
From the time of signing the informed consent form up to 24 months post-operatively.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Longitudinal Changes in Hip Functioning via Harris Hip Score (HHS)
Time Frame: Retrospective pre-operative baseline, and prospective assessments at 6 weeks, 3, 6, 12, 18, and 24 months post-operatively.
Periodic monitoring of absolute HHS tracking metrics and category shifts to determine the prospective 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.
Retrospective pre-operative baseline, and prospective assessments at 6 weeks, 3, 6, 12, 18, and 24 months post-operatively.
