Comparison of Restricted Versus Unrestricted Kinematic Alignment in 1ry TKA
A study testing Total knee arthroplasty in people with Osteoarthritis (OA) of the Knee and Total Knee Anthroplasty, run by Assiut University.
Trial summary
Knee osteoarthritis is a growing socioeconomic burden because of the ageing and obesity. By 2030, the majority of individuals undergoing knee arthroplasty in USA will be those younger than 65 years, with up to 1 million achieved annually. The definitive treatment for knee joint degeneration is total knee arthroplasty. Read more about this study

About this study
Official title: Comparison of Restricted Kinematic Alignment Versus Unrestricted Kinematic Alignment in Primary Total Knee Arthroplasty:- Randomized Controlled Trial
Knee osteoarthritis is a growing socioeconomic burden because of the ageing and obesity. By 2030, the majority of individuals undergoing knee arthroplasty in USA will be those younger than 65 years, with up to 1 million achieved annually.
The definitive treatment for knee joint degeneration is total knee arthroplasty.
Read the detailed description
Furthermore, the commonest technique is neutral mechanical alignment total knee arthroplasty. Latest studies have revealed that the mechanical alignment technique repeatedly causing substantial anatomical alterations with a widespread of complex collateral ligament imbalances, which are not repairable by collateral ligament release. Consequently, the total knee arthroplasty individuals walk with an abnormal gait, and they do not experience a normal knee joint. This may be one of the causes that up to 20% of total knee arthroplasty individuals are disappointed, and over 50% may have remaining symptoms.
Consequently, the conventional mechanical alignment technique has been recently challenged by a new alternative technique, namely unrestricted kinematic alignment proposed by Howell, as a possible solution to the high dissatisfaction following total knee arthroplasty, aiming at reproducing the constitutional tibiofemoral tridimensional alignment and knee laxity. It is almost a pure bone procedure with only exceptional collateral ligament release, which has been shown to reliably position knee components.
The restricted kinematic alignment protocol suggested by Vendittoli has been developed as an alternative to the unrestricted kinematic alignment for patients with an outlier or atypical knee anatomy. The restricted kinematic alignment is founded on five principles: hip-knee-ankle angle should be maintained within ± 3° postoperatively; a limitation to a maximum of 5° for lateral distal femoral angle and medial proximal tibial angle may be considered; restoration of collateral ligament balance should be achieved without the gap balancing technique; native femoral anatomy preservation is suggested over tibial one to maintain knee biomechanics; resurface resection must be accomplished on the unworn side with a thickness equivalent to the width of the implant;cut fine-tuning may be sought at the worn side.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Total knee arthroplastyProcedure or surgery
Also called Total knee replacement
Total knee arthroplasty (TKA) is a common orthopaedic surgery that involves replacing the articular surfaces (femoral condyles and tibial plateau) of the knee joint with smooth metal and highly cross-linked polyethylene plastic
| Study group | Role | What they receive |
|---|---|---|
| Unrestricted kinematic alignment | Experimental | reproducing the constitutional tibiofemoral tridimensional alignment and knee laxity. It is almost a pure bone procedure with only exceptional collateral ligament release, which has been shown to reliably position knee components. |
| Restricted kinematic alignment | Experimental | reproducing patient's constitutional knee anatomy within a safe range while avoiding extreme or pathological anatomies that have been demonstrated to exist. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Oxoford knee score
The Oxford Knee Score is a 12-item patient-reported outcomes specifically designed and developed to assess function and pain after total knee replacement arthroplasty. It is short, reproducible, valid and sensitive to clinically important changes.
Score each question from 0 to 4 with 4 being the best outcome. This method, when summed, produces overall scores running from 0 to 48 with 48 being the best outcome
Measured: 12 months
Secondary outcomes (2)
Knee Injury and Osteoarthritis Outcome Score
The Knee Injury and Osteoarthritis Outcome Score is a questionnaire designed to assess short and long-term patient-relevant outcomes following knee injury. The questionnaire is self-administered and assesses five outcomes: pain(9 items), symptoms(7 items), activities of daily living(17 items), sport and recreation function(5 items), and knee-related quality of life (4 items). The questionnaire meets basic criteria of outcome measures and can be used to evaluate the course of knee injury and treatment outcome.
A Likert scale is used and all items have five possible answer options scored from 0 (No problems) to 4 (Extreme problems) and each of the five scores is calculated as the sum of the items included.
Scores are transformed to a 0-100 scale, with zero representing extreme knee problems and 100 representing no knee problems as common in orthopaedic scales and generic measures. Scores between 0 and 100 represent the percentage of total possible score achieved.
Measured: 24 months
Forgotten Joint Score
The Forgotten Joint Score was designed to assess patient outcome in patients undergoing conservative or operative treatment of the knee. This questionnaire shows its strengths in patients with a good level of knee function and a low pain level. It has been designed specifically to reduce ceiling effects commonly associated with many patients reported outcome measures in this patient group, e.g. when assessing short- to mid-term results in total knee arthroplasty patients.
Every question is scored 1 (never) to 5 (mostly) according to the selected response categories. Thus, the raw score ranges from 12 to 60. The raw score is linearly transformed to a 0-100 scale and then reversed to obtain the final score.
Final score = 100 - ((sum(item01 to item12) - 12)/48*100) For the final 'Forgotten Joint Score -12' a high score indicates good outcome.
Measured: 24 months

Questions about this trial
What is this clinical trial studying?
A study testing Total knee arthroplasty in people with Osteoarthritis (OA) of the Knee and Total Knee Anthroplasty, run by Assiut University.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 19 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Yaser E Khalifa, Professor (+201005673622, yaserkhalifa@aun.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Oxoford knee score (time frame: 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06726993, which also lists 21 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Dec 2024.
