The philosophy of functional alignment has been proposed as a patient-specific philosophy of alignment with the intention to restore native knee kinematics, and intraoperative sensor technology has offered objective, real-time measurement of loads in the mediolateral compartments. There is little evidence on the integrated clinical outcome of functional alignment TKA with intraoperative sensors.\n\nPurpose: To compare clinical, functional, and biomechanical outcomes of functional alignment TKA with sensor guidance intraoperative in patients with primary knee osteoarthritis.\n\nMaterials and Methods: A prospective cohort study with 50 patients undergoing primary unilateral TKA using the principles of functional alignment and intraoperative pressure-sensing technology was used. The intraoperative medial and lateral compartment loads were measured as pre- and post-balancing. Clinical outcomes, including Knee Society Score (KSS), Visual Analogue Scale (VAS), range of motion, radiographic alignment, complication rates, and patient satisfaction, were assessed pre-operatively and at 6 months post-operatively. Statistical analysis was performed using a paired t-test and descriptive statistics, with P &lt; 0.05 considered significant.\n\nFindings: Patients had poor knee performance (KSS-knee 42.6 \u00b1 8.9; KSS-function 39.8 \u00b1 9.4) and a high pain level (VAS 7.6 \u00b1 1.1) pre-operatively. Significant mediolateral load imbalance at the start of the procedure (extension: 16.8 \u00b1 6.2 lbs; 90\u00b0 flexion: 10.9 \u00b1 5.1 lbs) was significantly decreased after sensor-guided adjustments (extension: 2.5 \u00b1 1.6 lbs; 90\u00b0 flexion: 1.9 \u00b1 1.4 lbs). KSS-knee (86.3 \u00b1 7.4), KSS-function (82.1 \u00b1 8.2), and VAS pain scales (1.8 \u00b1 0.9) recorded significant improvements (P &lt; 0.001) at 6 months post-operatively, and range of motion (118.6 \u00b1 9.8) was improved (P &lt; 0.001). In 88% of patients, acceptable limb positioning within the range of 3\u00b0 of the neutral position was possible. The overall patient satisfaction was 92, and the rate of complication was low, and no revision was made.\n\nConclusion: The TKA with intraoperative sensor technology functional alignment led to effective soft-tissue positioning, a strong functional outcome, great pain management, and high patient satisfaction, which appears to be a promising personalised approach for TKA.\n\nKeywords: Functional alignment, intraoperative sensors, patient-reported outcomes, soft-tissue balance, total knee arthroplasty.<\/jats:p>","DOI":"10.13107\/jocr.2026.v16.i07.7756","type":"journal-article","created":{"date-parts":[[2026,7,10]],"date-time":"2026-07-10T10:26:52Z","timestamp":1783679212000},"page":"585-591","update-policy":"https:\/\/doi.org\/10.13107\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Clinical Outcomes of Functional Alignment Total Knee Arthroplasty using Intraoperative Sensors: A Prospective Cohort Study"],"prefix":"10.13107","volume":"16","author":[{"given":"Ankit Kumar","family":"Garg","sequence":"first","affiliation":[{"name":"Department of Orthopaedics, ITSA Hospitals, Raipur, Chhattisgarh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shobhit","family":"Shobhit","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Pandit Deen Dayal Upadhyaya Hospital, Moradabad, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed Saleh","family":"Al Saifi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, 21 September University for Medicine and Applied Sciences, Sanaa, Yemen"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mrudul","family":"Kyada","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, GMERS Medical College, Vadnagar, Gujarat, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pritam","family":"Rahaman","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Institute of Post-Graduate Medical Education and Research and Seth Sukhlal Karnani Memorial Hospital, Kolkata, West Bengal, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gourab","family":"Biswas","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Max Superspeciality Hospital, New Delhi, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"5271","published-online":{"date-parts":[[2026]]},"container-title":["Journal of Orthopaedic Case Reports"],"original-title":[],"deposited":{"date-parts":[[2026,8,7]],"date-time":"2026-08-07T04:44:02Z","timestamp":1786077842000},"score":1,"resource":{"primary":{"URL":"https:\/\/jocr.co.in\/wp\/2026\/07\/clinical-outcomes-of-functional-alignment-total-knee-arthroplasty-using-intraoperative-sensors-a-prospective-cohort-study\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":0,"journal-issue":{"issue":"7","published-online":{"date-parts":[[2026]]},"published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.13107\/jocr.2026.v16.i07.7756","relation":{},"ISSN":["2321-3817"],"issn-type":[{"value":"2321-3817","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026]]},"assertion":[{"value":"Research Article","name":"content_type","label":"Content Type"},{"value":"Yes","name":"crosschecked","label":"CrossChecked"},{"value":"Yes","name":"peer_reviewed","label":"Peer Reviewed"},{"value":"10.13107\/jocr.2026.v16.i07.7756","name":"published","label":"Published"},{"value":"Creative Commons Attribution","name":"license","label":"License","explanation":{"URL":"https:\/\/creativecommons.org\/licenses\/by\/4.0"},"group":{"name":"rights","label":"Rights"}}]}}
