Use of Physical Therapy Following Total Knee Replacement Surgery: Implications of Orthopedic Surgeons' Ownership of Physical Therapy Services.

ABSTRACT:

Objective

To examine whether the course of physical therapy treatments received by patients who undergo total knee replacement (TKR) surgery differs depending on whether the orthopedic surgeon has a financial stake in physical therapy services.

Data

Sample of Medicare beneficiaries who underwent TKR surgery during the years 2007-2009.

Study design

We used regression analysis to evaluate the effect of physician self-referral on the following outcomes: (1) time from discharge to first physical therapy visit; (2) episode length; (3) number of physical therapy visits per episode; (4) number of physical therapy service units per episode; and (5) number of physical therapy services per episode expressed in relative value units.

Principal findings

TKR patients who underwent physical therapy treatment at a physician-owned clinic received on average twice as many physical therapy visits (8.3 more) than patients whose TKR surgery was performed by a orthopedic surgeon who did not self-refer physical therapy services (p < .001). Regression-adjusted results show that TKR patients treated at physician-owned clinics received almost nine fewer physical therapy service units during an episode compared with patients treated by nonself-referring providers (p < .001). In relative value units, this difference was 4 (p < .001). In contrast, episodes where the orthopedic surgeon owner does not profit from physical therapy services rendered to the patient look virtually identical to episodes where the TKR surgery was performed by a surgeon nonowner.

Conclusions

Physical therapists not involved with physician-owned clinics saw patients for fewer visits, but the composition of physical therapy services rendered during each visit included more individualized therapeutic exercises.

Project description:BackgroundIn older adults facing knee arthroplasty, the ability to resume downhill skiing postoperatively is unclear. This study aimed to determine the perspectives of Alberta orthopedic surgeons and senior residents regarding downhill skiing after total knee arthroplasty (TKA) or unicompartmental knee arthroplasty (UKA).MethodsIn May 2019, a Web-based survey was sent through the Alberta Orthopaedic Society to poll orthopedic surgeons performing arthroplasty and senior orthopedic residents (postgraduate year 4 or 5) in Alberta regarding the permissibility of downhill skiing after TKA or UKA. The survey also elicited information regarding under which conditions or restrictions, if any, surgeons would allow patients to return to downhill skiing, whether these recommendations were evidence based, and whether surgeons had seen complications from downhill skiing in their patients who had undergone knee arthroplasty.ResultsOf the 41 respondents, 21 (51%) were full-time fellowship-trained orthopedic surgeons, 15 (37%) were specialists with some arthroplasty in their practice, and 5 (12%) were orthopedic residents. Ten of 40 respondents (25%) would allow unrestricted downhill skiing after TKA, and 1 (2%) would not allow any skiing at all. The remaining 29 (72%) indicated that they might allow downhill skiing under specific conditions, with the top 3 being limitations on speed and intensity (29 [71%]), return of full range of motion and strength in the operative knee (26 [63%]), and years of downhill ski experience (23 [56%]). Fourteen respondents (34%) would allow unrestricted downhill skiing after UKA, and 27 (66%) would allow skiing with the same top 3 conditions as for TKA. Thirty-two respondents (78%) reported that their decisions were not evidence based, and 35 (85%) had never seen complications from downhill skiing after TKA or UKA.ConclusionAlberta orthopedic surgeons and senior residents are cautious regarding skiing after knee arthroplasty. The majority reported that their restrictions were not evidence based, which indicates the need for further investigation to develop an approach for surgeons to consistently and safely address return to downhill skiing after TKA or UKA.

Project description:ImportanceMany individuals who undergo total knee replacement (TKR) become long-term opioid users after TKR. Associations of physical therapy (PT) interventions before or after TKR with long-term use of opioids are not known.ObjectivesTo evaluate associations of PT interventions before and after TKR with long-term opioid use after TKR.Design, setting, and participantsThis cohort study used data from the OptumLabs Data Warehouse on 67 322 individuals aged 40 years or older who underwent TKR from January 1, 2001, to December 31, 2016, stratified by history of opioid use. The analyses for the study included data from January 1, 1999, to December 31, 2018.ExposuresAny PT interventions within 90 days before or after TKR, post-TKR PT dose as number of sessions (ie, 1-5, 6-12, and ≥13 sessions), post-TKR PT timing as number of days to initiation of care (ie, <30 days, 31-60 days, or 61-90 days after TKR), and post-TKR PT type (ie, active vs passive).Main outcomes and measuresThe association of pre- and post-TKR PT with risk of long-term opioid use occurring more than 90 days after TKR was assessed using logistic regression while adjusting for confounders, including age, sex, race and ethnicity (Asian, Black, Hispanic, or White), obesity, type of insurance, geographical location, and physical and mental health comorbidities.ResultsA total of 38 408 opioid-naive individuals (21 336 women [55.6%]; mean [SD] age, 66.2 [9.2] years) and 28 914 opioid-experienced individuals (18 426 women [63.7%]; mean [SD] age, 64.4 [9.3] years) were included. Receipt of any PT before TKR was associated with lower odds of long-term opioid use in the opioid-naive (adjusted odds ratio [aOR], 0.75 [95% CI, 0.60-0.95]) and opioid-experienced (aOR, 0.75 [95% CI, 0.70-0.80]) cohorts. Receipt of any post-TKR PT was associated with lower odds of long-term use of opioids in the opioid-experienced cohort (aOR, 0.75 [95% CI, 0.70-0.79]). Compared with 1 to 5 sessions of PT after TKR, 6 to 12 sessions (aOR, 0.82 [95% CI, 0.75-0.90]) and 13 or more sessions (aOR, 0.71 [95% CI, 0.65-0.77) were associated with lower odds in the opioid-experienced cohort. Compared with initiation of PT within 30 days after TKR, initiation 31 to 60 days or 61 to 90 days after TKR were associated with greater odds in the opioid-naive (31-60 days: aOR, 1.45 [95% CI, 1.19-1.77]; 61-90 days: aOR, 2.15 [95% CI, 1.43-3.22]) and opioid-experienced (31-60 days: aOR, 1.10 [95% CI, 1.02-1.18]; 61-90 days: aOR, 1.32 [95% CI, 1.12-1.55]) cohorts. Compared with passive PT, active PT was not associated with long-term opioid use in the opioid-naive (aOR, 1.00 [95% CI, 0.81-1.24]) or opioid-experienced (aOR, 0.99 [95% CI, 0.92-1.07]) cohorts.Conclusions and relevanceThis cohort study suggests that receipt of PT intervention before and after TKR, receipt of 6 or more sessions of PT care after TKR, and initiation of PT care within 30 days after TKR were associated with lower odds of long-term opioid use. These findings suggest that PT may help reduce the risk of long-term opioid use after TKR.

Project description:BackgroundTotal hip or knee arthroplasties (THA/TKA) show favorable long-term effects, yet the recovery process may take weeks to months. Physical therapy (PT) following discharge from hospital is an effective intervention to enhance this recovery process. To investigate the relation between recovery and postoperative PT usage, including the presence of comorbidities, 6 months after THA/TKA.MethodsMulticenter, observational study in primary THA/TKA patients who completed preoperative and 6 months postoperative assessments. The assessments included questions on PT use (yes/no and duration; long term use defined as ≥ 12 weeks), comorbidities (musculoskeletal, non-musculoskeletal, sensory comorbidities and frequency of comorbidities). Recovery was assessed with the HOOS/KOOS on all 5 subdomains. Logistic regression with long term PT as outcome was performed adjusted for confounding including an interaction term (comorbidity*HOOS/KOOS-subdomain).ResultsIn total, 1289 THA and 1333 TKA patients were included, of whom 95% received postoperative PT, 56% and 67% received postoperative PT ≥ 12 weeks respectively. In both THA and TKA group, less improvement on all HOOS/KOOS domain scores was associated with ≥ 12 weeks of postoperative PT (range Odds Ratios 0.97-0.99). In the THA group the impact of recovery was smaller in patient with comorbidities as non- musculoskeletal comorbidities modified all associations between recovery and postoperative PT duration (Odds Ratios range 1.01-1.05). Musculoskeletal comorbidities modified the associations between Function-in-Daily-Living-and Sport-and-recreation recovery and postoperative PT. Sensory comorbidities only had an effect on Sport-and-recreation recovery and postoperative PT. Also the frequency of comorbidities modified the relation between Function-in-Daily-Living, pain and symptoms recovery and postoperative PT. In the TKA group comorbidity did not modify the associations.ConclusionWorse recovery was associated with longer duration of postoperative PT suggesting that PT provision is in line with patients' needs. The impact of physical recovery on the use of long-term postoperative PT was smaller in THA patients with comorbidities.Trial registrationRegistered in the Dutch Trial Registry on March 13, 2012.

Project description:BACKGROUND: There is a lack of high quality evidence concerning the efficacy of total knee arthroplasty (TKA). According to international evidence-based guidelines, treatment of knee osteoarthritis (KOA) should include patient education, exercise and weight loss. Insoles and pharmacological treatment can be included as supplementary treatments. If the combination of these non-surgical treatment modalities is ineffective, TKA may be indicated. The purpose of this randomised controlled trial is to examine whether TKA provides further improvement in pain, function and quality of life in addition to optimised non-surgical treatment in patients with KOA defined as definite radiographic OA and up to moderate pain. METHODS/DESIGN: The study will be conducted in The North Denmark Region. 100 participants with radiographic KOA (K-L grade ?2) and mean pain during the previous week of ? 60 mm (0-100, best to worst scale) who are considered eligible for TKA by an orthopaedic surgeon will be included. The treatment will consist of 12 weeks of optimised non-surgical treatment consisting of patient education, exercise, diet, insoles, analgesics and/or NSAIDs. Patients will be randomised to either receiving or not receiving a TKA in addition to the optimised non-surgical treatment. The primary outcome will be the change from baseline to 12 months on the Knee Injury and Osteoarthritis Outcome Score (KOOS)(4) defined as the average score for the subscale scores for pain, symptoms, activities of daily living, and quality of life. Secondary outcomes include the five individual KOOS subscale scores, EQ-5D, pain on a 100 mm Visual Analogue Scale, self-efficacy, pain pressure thresholds, and isometric knee flexion and knee extension strength. DISCUSSION: This is the first randomised controlled trial to investigate the efficacy of TKA as an adjunct treatment to optimised non-surgical treatment in patients with KOA. The results will significantly contribute to evidence-based recommendations for the treatment of patients with KOA. TRIAL REGISTRATION: Clinicaltrials.gov reference: NCT01410409.
