Longitudinal Physical Fitness Data for Hip Osteoarthritis Patients After Surgery

Seventy-eight older hip osteoarthritis patients were assessed for physical fitness and activity before and after total hip arthroplasty. The dataset includes longitudinal measurements from two preoperative time points and 4-month and 1-year postoperative follow-ups. The study was published by Karger via figshare in 2026.

Use Cases

• Model the relationship between preoperative fitness measures like Timed Up and Go and 1-year postoperative step count using regression.
• Predict 1-year Six-Minute Walk Test distance from baseline demographics (age, gender) and preoperative strength tests.
• Analyze temporal patterns in moderate-to-vigorous physical activity and daily step count across four measurement time points.
• Classify patients based on recovery level using features like VO₂peak, leg strength changes, and step height asymmetry.

Strengths

• Longitudinal design with up to four measurement time points per patient.
• Objective physical activity data from hip-worn triaxial accelerometers.
• Assesses 24 distinct physical fitness parameters with demonstrated test-retest reliability.

Limitations

• Small cohort of 78 patients, with attrition reducing follow-up groups to 57 and 48 patients.
• Dataset is very small (29.4 KB), likely containing summary results rather than raw patient-level data.
• Cohort is geographically unspecified and has a high proportion (81%) of female participants, limiting generalizability.
