Abstract
Purpose
Prior to undergoing a cartilage restoration procedure of the knee, such as osteochondral allograft (OCA), osteochondral autograft (OAT), or autologous chondrocyte implantation (ACI), a diagnostic scope is often performed to evaluate the knee joint and characterize the cartilage damage. After diagnostic arthroscopy, a subset of patients experiences substantial relief and elects not to undergo a cartilage procedure. This study aims to identify factors which may be associated with successful outcomes after diagnostic arthroscopy.
Methods and Materials
99 patients scheduled to undergo diagnostic arthroscopy for cartilage evaluation, OCA, or ACI between May 2017 and March 2019 and were prospectively enrolled and age, BMI, procedure, size and location of lesion were collected. KOOS, IKDC and Marx were also collected pre-operatively as well as at 6-weeks, 6-months, and 1-year post-operatively. Patient demographics and lesion characteristics were compared between those who underwent only a diagnostic arthroscopy and those who underwent a cartilage restoration procedure.
Results
52 patients underwent only diagnostic arthroscopy (average age 32.48±9.55 years, BMI 28.21±5.72, 53.4% male). Average total lesion area was 4.29±3.22cm2. Average number of lesions was 1.4±0.71. 47 patients underwent cartilage restoration procedure (average age 34.04±8.17 years, BMI 28.08±4.95, 49.0% male). Average total lesion area was 4.98±2.37cm2. Average number of lesions was 1.40±0.64. No significant difference in total lesion area (p=0.22), number of lesions (p=0.97), sex (p=0.88), age (p=0.39) or BMI (0.92) was found between the two groups. In the diagnostic arthroscopy group, 28 (53.8%) had isolated patellofemoral cartilage damage, significantly more than the 15 (31.9%) in the cartilage procedure group that had isolated patellofemoral cartilage damage (p=0.02) .
Conclusion
While basic patient demographics and lesion size are not significantly different between those undergoing diagnostic arthroscopy alone and those electing to undergo cartilage restoration procedure, those with isolated patellofemoral cartilage damage are less likely to continue to a cartilage restoration procedure.
