Objectives: The current study investigated the effects of an eight week multimodal knee care intervention (MKCI) program on the intensity of knee pain (IKP), knee functional ability (KFA), pain free knee extension strength (P-KES), pain free single leg functional strength (P-SLS), pain free double leg functional strength (PDLS) and the quality of professional weightlifting (QOPL) among elite weightlifters. Methods: A total of eleven national Olympic weightlifters with knee pain (age: 21.55 ± 3.91 years, height: 161.09 ± 11.14 cm, and weight: 69.18 ± 15.99 kg) participated in a within subject, repeated measures, single blinded, self-controlled comparative study for a total period of 16 weeks. The first four weeks of the study was set as a self-controlled phase whereas the MKCI was started at the fourth week and continued over for a period of another eight weeks until 12th week. The IKP, KFA, P-KES, P-SLS and P-DLS and QOPL were measured repeatedly at first week (pre-baseline), fourth week (pre-intervention), 12th week (post-intervention) and 16th week (follow-up). Wilcoxon signed rank test and Friedman test were used to analyze the study measures. Results: The IKP, KFA, P-KES, P-SLS and P-DLS significantly improved by 16th week when compared to fourth week (P < 0.05). The KSC improved significantly by 12th week and 16th week (P < 0.05). The QOPL showed a trend of improvement over the study period. Conclusions: MKCI was a feasible program which showed positive effects in improving IKP, KFA, P-KES, P-SLS, P-DLS and KSC among elite weightlifters with knee pain.
