The Relationship Between Patient Expectations and Functional Outcomes in Patients Undergoing Cartilage Repair of the Knee: A Mixed Methods Study.

CONTEXT: Patient expectations have been shown to be a major predictor of outcomes. Fulfilled expectations have been linked to increased patient satisfaction and rehabilitation adherence. Expectations may be influenced by a variety of factors, including patient characteristics, preoperative function, or disease characteristics. It is currently unknown what factors may influence patient expectations prior to cartilage repair of the knee, and to what degree. Furthermore, understanding the importance and values of those expectations for recovery using mixed methods has not previously been conducted in this patient population. The purpose of this mixed methods study is to examine and explore the relationships between patient expectations and functional outcome in patients undergoing cartilage repair of the knee. DESIGN: A mixed methods design was used. METHODS: Twenty-one patients scheduled to undergo cartilage repair of the knee were included. Participants completed the Hospital for Special Surgery Knee Surgery Expectations Survey and the Knee Injury and Osteoarthritis Outcome Score at their preoperative visit. Knee Injury and Osteoarthritis Outcome Scores were also obtained at 3 and 6 months postsurgery. A selected sample of 6 participants participated in semi-structured interviews 6 months postsurgery. Pearson correlation coefficients were used to determine relationships between expectations and functional outcome. RESULTS: Patients have moderate expectations for recovery, and these expectations were positively associated with preoperative pain, activities of daily living, and quality of life. Expectations also correlated with symptoms 3 months postsurgery, but there were no other significant correlations between preoperative expectations and postoperative function in the short term. Four qualitative themes emerged as participants described how previous recovery experiences shaped their expectations. CONCLUSIONS: Formalized patient and caregiver education, prehabilitation, and the use of psychological skills during rehabilitation may help to manage patient expectations and provide more focused and individualized care, thus improving outcomes.

Patient Experiences of Recovery After Autologous Chondrocyte Implantation: A Qualitative Study.

CONTEXT: The recovery process after autologous chondrocyte implantation (ACI) can be challenging for patients and clinicians alike due to significant functional limitations and a lengthy healing time. Understanding patients' experiences during the recovery process may assist clinicians in providing more individualized care. OBJECTIVE: To explore and describe patients' experiences during the recovery process after ACI. DESIGN: Qualitative study. SETTING: Orthopaedic clinic. PATIENTS OR OTHER PARTICIPANTS: Participants from a single orthopaedic practice who had undergone ACI within the previous 12 months were purposefully selected. DATA COLLECTION AND ANALYSIS: Volunteers participated in 1-on-1 semistructured interviews to describe their recovery experiences after ACI. Data were analyzed using the process of horizontalization. RESULTS: Seven patients (2 men, 5 women; age = 40.7 ± 7.5 years, time from surgery = 8.7 ± 4.2 months) participated. Four themes and 6 subthemes emerged from the data and suggested that the recovery process is a lengthy and emotional experience. Therapy provides optimism for the future but requires a collaborative effort among the patient, surgeon, rehabilitation provider, and patient's caregiver(s). Furthermore, patients expressed frustration that their expectations for recovery did not match the reality of the process, including greater dependence on caregivers than expected. CONCLUSIONS: Patients' expectations should be elicited before surgery and managed throughout the recovery process. Providing preoperative patient and caregiver education and encouraging preoperative rehabilitation can assist in managing expectations. Establishing realistic goals and expectations may improve rehabilitation adherence, encourage optimism for recovery, and improve outcomes in the long term.

Feasibility of conducting a web-based survey of patient-reported outcomes and rehabilitation progress.

BACKGROUND: Web-based surveys provide an efficient means to track clinical outcomes over time without the use of clinician time for additional paperwork. Our purpose was to determine the feasibility of utilizing web-based surveys to capture rehabilitation compliance and clinical outcomes among postoperative orthopedic patients. The study hypotheses were that (a) recruitment rate would be high (>90%), (b) patients receiving surveys every two weeks would demonstrate higher response rates than patients that receive surveys every four weeks, and (c) response rates would decrease over time. METHODS: The study deaign involved a longitudinal cohort. Surgical knee patients were recruited for study participation during their first post-operative visit (n = 59, 34.9 ± 12.0 years of age). Patients with Internet access, an available email address and willingness to participate were counter-balanced into groups to receive surveys either every two or four weeks for 24 weeks post-surgery. The surveys included questions related to rehabilitation and questions from standard patient-reported outcome measures. Outcome measures included recruitment rate (participants consented/patients approached), eligibility (participants with email/participants consented), willingness (willing participants/participants eligible), and response rate (percentage of surveys completed by willing participants). RESULTS: Fifty-nine patients were approached regarding participation. Recruitment rate was 98% (n = 58). Eligibility was 95% (n = 55), and willingness was 91% (n = 50). The average response rate was 42% across both groups. There was no difference in the median response rates between the two-week (50%, range 0-100%) and four-week groups (33%, range 0-100%; p = 0.55). CONCLUSIONS: Although patients report being willing and able to participate in a web-based survey, response rates failed to exceed 50% in both the two-week and four-week groups. Furthermore, response rates began to decrease after the first three months postoperatively. Therefore, supplementary data collection procedures may be necessary to meet established research quality standards.

SUSTAINED ISOMETRIC SHOULDER CONTRACTION ON MUSCULAR STRENGTH AND ENDURANCE: A RANDOMIZED CLINICAL TRIAL.

BACKGROUND: The Advanced Throwers Ten Exercise Program incorporates sustained isometric contractions in conjunction with dynamic shoulder movements. It has been suggested that incorporating isometric holds may facilitate greater increases in muscular strength and endurance. However, no objective evidence currently exists to support this claim. HYPOTHESIS/PURPOSE: The purpose of this research was to compare the effects of a sustained muscle contraction resistive training program (Advanced Throwers Ten Program) to a more traditional exercise training protocol to determine if increases in shoulder muscular strength and endurance occur in an otherwise healthy population. It was hypothesized that utilizing a sustained isometric hold during a shoulder scaption exercise from the Advanced Throwers Ten would produce greater increases in shoulder strength and endurance as compared to a traditional training program incorporating a isotonic scapular plane abduction (scaption) exercise. STUDY DESIGN: Randomized Clinical Trial. METHOD: Fifty healthy participants were enrolled in this study, of which 25 were randomized into the traditional training group (age: 26 ± 8, height:172 ± 10 cm, weight: 73 ± 13 kg, Marx Activity Scale: 11 ± 4) and 25 were randomized to the Advanced Throwers Ten group (age: 28 ± 9, height: 169 ± 23 cm, weight: 74 ± 16 kg, Marx Activity Scale: 11 ± 5). No pre-intervention differences existed between the groups (P>0.05). Arm endurance and strength data were collected pre and post intervention using a portable load cell (BTE Evaluator, Hanover, MD). Both within and between group analyses were done in order to investigate average torque (strength) and angular impulse (endurance) changes. RESULTS: The traditional and Advanced Throwers Ten groups both significantly improved torque and angular impulse on both the dominant and non-dominant arms by 10-14%. There were no differences in strength or endurance following the interventions between the two training groups (p>0.75). CONCLUSIONS: Both training approaches increased strength and endurance as the muscle loads were consistent between protocols indicating that either approach will have positive effects. LEVEL OF EVIDENCE: Level 2.

The role of rehabilitation following autologous chondrocyte implantation: a retrospective chart review.

PURPOSE/BACKGROUND: Clinical outcomes following autologous chondrocyte implantation (ACI) are influenced by multiple factors, including patient demographics, lesion characteristics, quality of the surgical repair, and post-operative rehabilitation. However, it is currently unknown what specific characteristics of rehabilitation have the greatest influence on clinical outcomes following ACI. The purpose of this study was to conduct a retrospective chart review of patients undergoing ACI with the intent to describe this patient population's demographics, clinical outcomes, and rehabilitation practices. This study aimed to assess the consistency of the documentation process relative to post-operative rehabilitation in order to provide information and guide initiatives for improving the quality of rehabilitation practices following ACI. METHODS: The medical records of patients treated for chondral defect(s) of the knee who subsequently underwent the ACI procedure were retrospectively reviewed. A systematic review of medical, surgical, and rehabilitation records was performed. In addition, patient-reported outcome measures (IKDC, WOMAC, Lysholm, SF-36) recorded pre-operatively, and 3, 6, and 12 months post-operatively were extracted from an existing database. RESULTS: 20 medical charts (35.9 ± 6.8 years; 9 male, 11 female) were systematically reviewed. The average IKDC, WOMAC, Lysholm, and SF-36 scores all improved from baseline to 3, 6 and 12 months post-operatively, with the greatest changes occurring at 6 and 12 months. There was inconsistent documentation relative to post-operative rehabilitation, including CPM use, weight-bearing progression, home-exercise compliance, and strength progressions. CONCLUSIONS: Due to variations in the documentation process, the authors were unable to determine what specific components of rehabilitation influence the recovery process. In order to further understand how rehabilitation practices influence outcomes following ACI, specific components of the rehabilitation process must be consistently and systematically documented over time. LEVEL OF EVIDENCE: 2C.
