Total knee replacement surgery for knee osteoarthritis has increased tremendously during the past few decades. But still, 15-19% of the patients are not satisfied with the surgical outcome. Therefore, alternative ways of aligning a TKR have gained interest. The principle of strict KA is to restore the native joint line of the knee by positioning the femoral and tibial components in such a way so as to attain the pre-arthritic state and to maintain the balance of knee through the entire range of motion and three-dimensional correction— coronal, sagittal, rotational. Narayanasamy Ragunanthan et al have designed their technique of personalized kinematic TKR with conventional instruments. This is the first mid-term survivorship analysis that has been done among the Indian population. It has been published in ‘Indian journal of orthopedics.’ A prospective study was done on the patients treated for knee osteoarthritis by a single surgeon in a single center. All the 124 knees (102 patients) were operated by our technique of personalized kinematic TKR where the thickness of distal femoral and tibial cuts was calculated by measuring cartilage and bone wear and calipered resection technique was carried out with conventional instruments. Key findings of the study: • In the study, all the patients (except one) were followed-up for a mean duration of 5.8 years (range 5–7.5 years). • Out of 102 patients, 32 were men and 70 were women. Out of 102 patients, 80 had undergone unilateral and 22 had undergone bilateral total knee arthroplasty • Oxford Knee Score increased from 25.82 ± 6.01 preoperatively to 45.14 ± 5.98 postoperatively and FJS improved from 14.53 ± 4.06 preoperatively to 93.14 ± 12.21 at 1-year follow-up and none of the patients underwent revision surgery. The authors concluded that – “this prospective study shows that personalized kinematic total knee arthroplasty in the Indian population results in high satisfaction rates as well as good clinical outcomes with no revisions at minimum 5-year follow-up.” Further reading: Mid-term Survivorship Analysis of Personalized Kinematic Total Knee Arthroplasty: A Single-Surgeon and Single-Centre Prospective Study Among the Indian Population Narayanasamy Ragunanthan et al Indian Journal of Orthopaedics (2025) 59:937–944 https://doi.org/10.1007/s43465-025-01384-8
