Background and Purpose: The most common joint disorder in the United States is osteoarthritis (OA). Knee OA occurs in 10% men and 13% in women aged 60 years or older. Hip instability is commonly defined as hip joint unsteadiness that may cause pain. Joint restrictions and lack of hip strength may be associated with these two conditions. However, there is limited literature on hip strengthening and mobilizations on positive outcomes with hip instability. Therefore, the purpose of this case report was to utilize hip strengthening and mobilizations interventions on a patient with hip instability and knee OA. Case Description: The patient was a 71-year-old male who presented with radiating hip and knee pain. Lower extremity myotomes, range of motion (ROM), the Lower Extremity Functional Scale (LEFS), Single Limb Stance Test (SLST), and Plumb line test were used to evaluate improvements. Interventions implemented included lower extremity strengthening, stretching, manual therapy, and balance training. Outcomes: The patient attended 11 visits over 6 weeks. LEFS improved from 47/80 to 53/80 and SLST on the right leg with eyes open from 7 seconds to 10 seconds. Discussion: Although the patient showed relatively small improvements, he reported a reduction in difficulty and pain during his work and daily living activities throughout the 6-week rehabilitation process. The patient was educated on his posture and proper body mechanics, which may have contributed to his reduction in radiating hip and knee pain. Utilizing hip strengthening and mobilization interventions for treatment of hip instability and knee OA may have positive outcomes but requires further investigation. Future research should focus on lower extremity strengthening and manual therapy for knee OA and hip instability.
