Abstract

Athletic injuries are commonly implicated in the development of early osteoarthritic (EOA) changes in the knee. These changes have a significant impact on athletic performance, and therefore the early detection of EOA is paramount. The objective of the study is to assess the impact of different interventions on individuals with EOA, particularly focusing on recreational athletes. The study aims to evaluate the effectiveness of three treatment groups in improving various aspects related to knee EOA, including pain, range of motion, strength, and function. A study was undertaken with 48 recreational athletes with EOA who were assigned to one of three groups by the referring orthopedic surgeon: collagen (Col), exercise (Ex), or collagen and exercise (ColEx) groups. All the participants received their respective group-based intervention for 12 weeks. Visual analog scale (VAS), knee flexion range of motion (ROM) knee flexors and extensors strength, and KOOS were assessed at baseline, and after 4 weeks, 8 weeks, and 12 weeks of intervention. VAS for activity improved in all treatment groups, with no difference between groups. The between-group analysis for knee ROM revealed a significant difference (p = 0.022) in the Col vs. Ex group at 12 weeks. The knee flexor and extensor strength and the KOOS scores improved considerably in the Ex and the ColEx group (p < 0.05) at 12 weeks. Exercise therapy improved pain, strength and function in subjects with EOA, whereas the association of collagen seems to have accentuated the effects of exercise in bringing about clinical improvements.
