Good enough for a service connection?

Yes, your documented PHA complaints of knee and back pain are a strong foundational element to establish service connection, but they are not sufficient alone; you must build a complete claim by satisfying the three key elements defined in 38 CFR 3.303: (1) a current diagnosed disability, (2) evidence of an in-service event or aggravation, and (3) a medical nexus linking the two. Your PHAs directly satisfy the second element by providing contemporaneous evidence of symptoms during service, which is crucial as established in cases like *Buchanan v. Nicholson* where consistent complaints in service records were deemed compelling. Your personal statement detailing the physical demands of your job can further support the in-service aggravation. However, the critical missing piece is a formal, current diagnosis for your knees (e.g., degenerative arthritis likely rated under Diagnostic Code 5003) and back (e.g., lumbosacral strain under Diagnostic Code 5237) from a medical professional, along with a nexus opinion—preferably from a VA or private physician—stating it is "at least as likely as not" that your current conditions are related to your service and physical duties (*DeLuca v. Brown*). Your actionable next steps are: 1) Obtain current diagnoses via VA or private medical exams, 2) Secure a nexus letter from a treating physician, 3) File a fully developed claim (FDC) with your service PHAs, personal statement, buddy statements, and all medical evidence, specifically citing 38 CFR 4.130 for mental health if applicable, but for musculoskeletal issues, reference the relevant musculoskeletal diagnostic codes in 38 CFR Part 4, Schedule for Rating Disabilities. This structured approach significantly increases your likelihood of a grant.
