Selected reading
Medial stabilization.
16 papers on bearing geometry, measured motion, and clinical outcomes. Reviews may include the primary studies listed here.
Motion · Moonot et al. · 2009Tibiofemoral kinematic analysis of knee flexion for a medial pivot knee
Fluoroscopy · 13 patients / 15 knees
Medial-centered motion during lunge and kneeling, with less tibial rotation than reported for native knees.
Small, activity-specific series; no comparative patient-outcome claim.
Read published paper ↗Outcomes · Scott & Gray · 2022Outcomes are Better With a Medial-Stabilized vs a Posterior-Stabilized Total Knee Implanted With Kinematic Alignment
Randomized trial · 200 patients · KA · 2 years
MS had greater maximum flexion (132° vs 124°) and a higher Forgotten Joint Score (68.3 vs 58.3).
Single center and specific implant systems. Not every enrollee completed every two-year measure; results do not isolate the polyethylene alone.
Read published paper ↗Motion · Alesi et al. · 2022No kinematical difference between ultra-congruent and medial-congruent total knee arthroplasty when implanted with mechanical alignment
Dynamic RSA · 8 MC / 8 UC · MA
No detected difference in medial-pivot behavior during sit-to-stand; clinical flexion was greater with MC.
Small sample; absence of a detected difference is not proof of equivalence.
Read published paper ↗Outcomes · Hoskins et al. · 2022Medial Pivot Designs Versus Conventional Bearing Types in Primary Total Knee Arthroplasty: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
Systematic review · 8 randomized trials · 725 knees
Pooled MP-versus-PS comparisons found no clear advantage in measured clinical outcomes.
One high-risk-of-bias trial excluded from pooling; insufficient randomized evidence for other bearing comparisons.
Read published paper ↗Overview · Romano et al. · 2025Medial Congruent and Medial Pivot Inserts in Total Knee Arthroplasty: A Scoping Review
Scoping review · 39 articles · 6,143 TKAs
Generally favorable outcomes with both MC and MP constructs; terminology and surgical approaches vary.
Heterogeneous evidence does not establish equivalence, a universal PCL strategy, or comparative longevity.
Read published paper ↗Motion · Nelson-Tranum et al. · 2025Implant design may influence knee flexor activation patterns during stair ascent and descent
Biomechanics and EMG · 52 patients · 1 year
Greater medial AP constraint was associated with lower biceps femoris activation during stair tasks.
Muscle activation is not proof of easier stairs, reduced fatigue, or superior patient outcomes.
Read published paper ↗Outcomes · French et al. · 2020A Single Surgeon Series Comparing the Outcomes of a Cruciate Retaining and Medially Stabilized Total Knee Arthroplasty Using Kinematic Alignment Principles
Prospective comparison · 90 patients · KA · 1 year
Higher FJS and selected quality-of-life scores with MS; most other measures were comparable.
Small, nonrandomized, single-surgeon comparison with short follow-up.
Read published paper ↗Outcomes · Jones et al. · 2023Better flexion and early recovery with medial-stabilized vs single-radius total knee arthroplasty with kinematic alignment: Two-year clinical results
Retrospective cohort comparison · 210 patients · KA
MS had greater flexion from six months to two years and selected early pain advantages.
Comparison across separate trials, not a direct randomized comparison. The MS cohort overlaps the Scott–Gray trial.
Read published paper ↗Outcomes · Chang et al. · 2021A Prospective Randomized Controlled Trial Comparing Medial-Pivot versus Posterior-Stabilized Total Knee Arthroplasty
Randomized trial · 88 patients · 2 years
No detected differences in ROM or measured patient-reported outcomes between MP and PS.
Findings apply to the studied devices and follow-up; no significant difference does not establish equivalence.
Read published paper ↗Motion · Tsubosaka et al. · 2021Mid-flexion stability in the anteroposterior plane is achieved with a medial congruent insert in cruciate-retaining total knee arthroplasty for varus osteoarthritis
Intraoperative comparison · 30 varus OA knees · CR-TKA
MC reduced AP translation under manual stress at 45° compared with CR inserts. Varus–valgus laxity was comparable.
Intraoperative mechanics, not evidence that MC prevents long-term clinical instability.
Read published paper ↗Motion · Kaneda et al. · 2022Kinematically Aligned Total Knee Arthroplasty Using Medial Pivot Knee Prosthesis Enhances Medial Pivot Motion
Comparative kinematics · 13 knees / 9 patients · 1 year
KA knees showed greater lateral posterior travel and femoral external rotation than MA knees with the studied MP implant.
Exploratory: 8 KA and 5 MA knees. Does not establish clinical superiority.
Read published paper ↗Outcomes · Tso et al. · 2021Clinical and Patient-Reported Outcomes of Medial Stabilized Versus Non-Medial Stabilized Prostheses in Total Knee Arthroplasty: A Systematic Review and Meta-Analysis
Systematic review · 21 studies / 13 pooled
FJS favored MS by 13.83 points, just below the review’s chosen clinical-importance threshold of 14; other differences were absent or not clinically important.
Thresholds and study populations vary; statistical significance alone is not clinical importance.
Read published paper ↗Outcomes · Frye et al. · 2021A Medial Congruent Polyethylene Offers Satisfactory Early Outcomes and Patient Satisfaction in Total Knee Arthroplasty
Retrospective cohort · 327 TKAs · 1 year
MC improved selected early pain, FJS, and satisfaction measures; KOOS/PROMIS and MC-versus-PS satisfaction were similar.
Observational, short-term evidence; does not establish a universal satisfaction advantage.
Read published paper ↗Motion · Schütz et al. · 2019Kinematic Evaluation of the GMK Sphere Implant During Gait Activities: A Dynamic Videofluoroscopy Study
Dynamic fluoroscopy · 3 groups of 10 patients
The studied Sphere construct limited medial AP excursion while permitting lateral travel and axial rotation.
Selected good-outcome patients and specific devices; industry-supported study.
Read published paper ↗Motion · Delman et al. · 2021The posterolateral upslope of a low-conforming insert blocks the medial pivot during a deep knee bend in TKA: a comparative analysis of two implants with different insert conformities
Bilateral comparison · 25 patients · KA
The medial ball-in-socket/flat lateral construct maintained a medial pivot. A posterolateral upslope was proposed to explain different motion with the low-conforming CR construct.
Different implant systems, PCL management, and follow-up. No difference in median patient-reported outcomes.
Read published paper ↗Motion · Gray et al. · 2020Comparison of posterior-stabilized, cruciate-retaining, and medial-stabilized knee implant motion during gait
Randomized implant groups · gait imaging · 74 patients
MS showed less AP drawer/paradoxical translation and a medial center of rotation.
All three implant designs still differed from healthy knees. Motion is not a patient-outcome measure.
